+* Endpoint for adding targets now returns the correct id
+* CLI now correctly errors and doesn't error when sending requests
+* Fixed possible infinite loop when removing old build images
+* Check whether build image still exists before starting build
+* Don't run makepkg `prepare()` function twice
+* Don't buffer stdout in Docker containers
+
+## [0.4.0](https://git.rustybever.be/vieter-v/vieter/src/tag/0.4.0)
+
+### Added
+
+* Server port can now be configured
+* Targets now have a 'kind' field describing whether it's a Git repository or a
+  URL to a PKGBUILD
+* Targets with kind 'url' can provide a direct URL to a PKGBUILD instead of
+  providing a Git repository
+* CLI commands for searching the AUR & directly adding packages
+* HTTP routes for removing packages, arch-repos & repos
+* All endpoints serving files now support HTTP byte range requests
+* Better CLI UX
+    * When adding targets, the ID of the created target is returned
+    * The `-r` flag only shows raw data of action
+        * When adding a target, only ID is shown and not surrounding text
+        * Tabled output returns a tab-separated list (easy to script using
+          `cut`)
+
+### Changed
+
+* Moved all API routes under `/v1` namespace
+* Renamed `vieter repos` to `vieter targets`
+* Renamed `/api/v1/repos` namespace to `/api/v1/targets`
+* Branch name for 'git' targets is now optional; if not provided, the
+  repository will be cloned with the default branch
+* Build containers now explicitely set the PATH variable
+* Refactor of web framework
+* API endpoints now return id of newly created entries
+* Repo POST requests now return information on published package
+* `api` can no longer be used as a repository name
+* CLI client now allows setting values to an empty value
+
+### Removed
+
+* md5 hashes are no longer calculated for packages
+
+## [0.3.0](https://git.rustybever.be/vieter-v/vieter/src/tag/0.3.0)
+
+Nothing besides bumping the versions.
+
+## [0.3.0-rc.1](https://git.rustybever.be/vieter-v/vieter/src/tag/0.3.0-rc.1)
+
+### Added
+
+* Database migrations
+* Improved GitRepo & BuildLog API
+    * Pagination using `limit` & `offset` query params
+    * GitRepo: filter by repo
+    * BuildLog: filter by start & end date, repo, exit code & arch
+* CLI flags to take advantage of above API improvements
+* Added CLI command to generate all man pages
+* PKGBUILDs now install man pages
+* Hosted CLI man pages ([vieter(1)](https://rustybever.be/man/vieter/vieter.1.html))
+* Proper HTTP API docs ([link](https://rustybever.be/docs/vieter/api/))
+
+### Changed
+
+* Packages from target repo are available during builds
+    * This can be used as a basic way to support AUR dependencies, by adding
+      the dependencies to the same repository
+* Every build now updates its packages first instead of solely relying on the
+  updated builder image
+* Build logs now show commands being executed
+
+### Fixed
+
+* `POST /api/logs` now correctly uses epoch timestamps instead of strings
+
+## [0.3.0-alpha.2](https://git.rustybever.be/vieter-v/vieter/src/tag/0.3.0-alpha.2)
+
+### Added
+
+* Web API for adding & querying build logs
+* CLI commands to access build logs API
+* Cron build logs are uploaded to above API
+* Proper ASCII table output in CLI
+* `vieter repos build id` command to run builds locally
+
+### Removed
+
+* `vieter build` command
+    * This command was used alongside cron for periodic builds, but this has
+      been replaced by `vieter cron`
+
+### Changed
+
+* `vieter build` command now only builds a single repository & uploads the
+  build logs
+* Official Arch packages are now split between `vieter` & `vieter-git`
+    * `vieter` is the latest release
+    * `vieter-git` is the latest commit on the dev branch
+* Full refactor of Docker socket code
+
+## [0.3.0-alpha.1](https://git.rustybever.be/vieter-v/vieter/src/tag/0.3.0-alpha.1)
+
+### Changed
+
+* Switched from compiler fork to fully vanilla compiler mirror
+* `download_dir`, `repos_file` & `repos_dir` config values have been replaced
+  with `data_dir`
+* Storage of metadata (e.g. Git repositories) is now done using Sqlite
+
+### Added
+
+* Implemented own cron daemon for builder
+    * Build schedule can be configured globally or individually per repository
+* Added CLI command to show detailed information per repo
+
+### Fixed
+
+* Binary no longer panics when an env var is missing
+
+## [0.2.0](https://git.rustybever.be/vieter-v/vieter/src/tag/0.2.0)
+
+### Changed
+
+* Better config system
+    * Support for both a config file & environment variables
+    * Each env var can now be provided from a file by appending it with `_FILE`
+      & passing the path to the file as value
+* Revamped web framework
+    * All routes now return proper JSON where applicable & the correct status
+      codes
+
+### Added
+
+* Very basic build system
+    * Build is triggered by separate cron container
+    * Packages build on cron container's system
+    * A HEAD request is used to determine whether a package should be rebuilt
+      or not
+    * Hardcoded planning of builds
+    * Builds are sequential
+* API for managing Git repositories to build
+* CLI to list, add & remove Git repos to build
+* Published packages on my Vieter instance
+* Support for multiple repositories
+* Support for multiple architectures per repository
+
+### Fixed
+
+* Each package can now only have one version in the repository at once
+  (required by Pacman)
+* Packages with unknown fields in .PKGINFO are now allowed
+* Old packages are now properly removed
+
+## [0.1.0](https://git.rustybever.be/vieter-v/vieter/src/tag/0.1.0)
 
 ### Changed
 
 * Improved logging

 # Vieter
 
-Vieter is a re-implementation of the Pieter project. The goal is to create a
+I host documentation for Vieter over at https://rustybever.be/docs/vieter/. API
-simple PKGBUILD-based build system, combined with a self-hosted Arch
+documentation for the current codebase can be found at
-repository. This would allow me to periodically re-build AUR packages (or
+https://rustybever.be/api-docs/vieter/.
-PKGBUILDs I created myself), & make sure I never have to compile anything on my
+
-own systems, making my updates a lot quicker.
+For more information, questions or just a chat, there's
+[#vieter:rustybever.be](https://matrix.to/#/#vieter:rustybever.be) on Matrix!
+
+## Overview
+
+Vieter is a restart of the Pieter project. The goal is to create a simple,
+lightweight self-hostable Arch repository server, paired with a system that
+periodically builds & publishes select Arch packages. This would allow me to
+build AUR packages (or PKGBUILDs I created myself) "in the cloud" & make sure I
+never have to compile anything on my own systems, making my updates a lot
+quicker.
 
 ## Why V?
 
 I chose [V](https://vlang.io/) as I've been very intrigued by this language for
 a while now. I wanted a fast language that I could code while relaxing, without
 having to exert too much mental effort & V seemed like the right choice for
-that.
+that. Sadly, this didn't quite turn out the way I expected, but I'm sticking
-
+with it anyways ;p
-### Custom Compiler
-
-Currently, this program only works with a very slightly modified version of the
-V standard library, and therefore the compiler. The changes that are made to
-the standard V release can be found in the [patches](/patches) directory. You
-can obtain this modified version of the compiler by running `make v`, which
-will download, patch & build the compiler. Afterwards, all make commands that
-require the V compiler will use this new binary.
 
 ## Features
 
-The project will consist of a server-agent model, where one or more builder
+* Arch repository server
-nodes can register with the server. These agents communicate with the Docker
+    * Support for multiple repositories & multiple architectures
-daemon to start builds, which are then uploaded to the server's repository. The
+    * Endpoints for publishing new packages
-server also allows for non-agents to upload packages, as long as they have the
+    * API for managing repositories to build
-required secrets. This allows me to also develop non-git packages, such as my
+* Build system
-terminal, & upload them to the servers using CI.
+    * Periodic rebuilding of packages
+    * Prevent unnecessary rebuilds
 
-## Directory Structure
+## Building
 
-The data directory consists of three main directories:
+Besides a V installer, Vieter also requires the following libraries to work:
 
-* `downloads` - This is where packages are initially downloaded. Because vieter
+* libarchive
-  moves files from this folder to the `pkgs` folder, these two folders should
+* openssl
-  best be on the same drive
+* sqlite3
-* `pkgs` - This is where approved package files are stored.
+
-* `repos` - Each repository gets a subfolder here. The subfolder contains the
+Vieter also depends on some external V modules which you can install using `cd
-  uncompressed contents of the db file.
+src && v install`. Make sure to keep these dependencies up to date using `v
-    * Each repo subdirectory contains the compressed db & files archive for the
+update`.
-      repository, alongside a directory called `files` which contains the
+
-      uncompressed contents.
+### Compiler
+
+V is developed using a specific compiler commit that is usually updated
+whenever a new version is released. Information on this can be found in the
+[tools](https://git.rustybever.be/vieter-v/tools) repository.
+
+## Contributing
+
+If you wish to contribute to the project, please take note of the following:
+
+* Rebase instead of merging whenever possible, e.g. when updating your branch
+  with the dev branch.
+* Please follow the
+  [Conventional Commits](https://www.conventionalcommits.org/) style for your
+  commit messages.
+
+### Writing documentation
+
+The `docs` directory contains a Hugo site consisting of all user &
+administrator documentation. `docs/api` on the other hand is a
+[Slate](https://github.com/slatedocs/slate) project describing the HTTP web
+API.
+
+To modify the Hugo documentation, you'll need to install Hugo. Afterwards, you
+can use the following commands inside the `docs` directory:
+
+```sh
+# Build the documentation
+hugo
+
+# Host an auto-refreshing web server with the documentation. Important to note
+# is that the files will be at `http://localhost:1313/docs/vieter` instead of
+# just `http://localhost:1313/`
+hugo server
+```
+
+For the Slate docs, I personally just start a docker container:
+
+```sh
+docker run \
+    --rm \
+    -p 4567:4567 \
+    --name slate \
+    -v $(pwd)/docs/api/source:/srv/slate/source slatedocs/slate serve
+```
+
+This will make the Slate docs available at http://localhost:4567. Sadly, this
+server doesn't auto-refresh, so you'll have to manually refresh your browser
+every time you make a change.

+# Repository
+
+Besides providing a RESTful API, the Vieter server is also a Pacman-compatible
+repository server. This section describes the various routes that make this
+possible.
+
+## Get a package archive or database file
+
+```shell
+curl -L https://example.com/bur/x86_64/tuxedo-keyboard-3.0.10-1-x86_64.pkg.tar.zst
+```
+
+This endpoint is really the entire repository. It serves both the package
+archives & the database files for a specific arch-repo. It has three different
+behaviors, depending on `filename`:
+
+* If the file extension is one of `.db`, `.files`, `.db.tar.gz` or
+  `.files.tar.gz`, it tries to serve the requested database file.
+* If the filename contains `.pkg`, it serves the package file.
+* Otherwise, it assumes `filename` is the name & version of a package inside
+  the repository (e.g. `vieter-0.3.0_alpha.2-1`) & serves that package's `desc`
+  file from inside the database archive.
+
+<aside class="notice">
+
+The final option might sound a little strange, but it's used by the build
+system to determine whether a package needs to be rebuilt.
+
+</aside>
+
+### HTTP Request
+
+`GET /:repo/:arch/:filename`
+
+### URL Parameters
+
+Parameter | Description
+--------- | -----------
+repo | Repository containing the package
+arch | Arch-repo containing the package
+filename | actual filename to request
+
+## Check whether file exists
+
+```shell
+curl -L https://example.com/bur/x86_64/tuxedo-keyboard-3.0.10-1-x86_64.pkg.tar.zst
+```
+
+The above request can also be performed as a HEAD request. The behavior is the
+same, except no data is returned besides an error 404 if the file doesn't exist
+& an error 200 otherwise.
+
+### HTTP Request
+
+`GET /:repo/:arch/:filename`
+
+### URL Parameters
+
+Parameter | Description
+--------- | -----------
+repo | Repository containing the package
+arch | Arch-repo containing the package
+filename | actual filename to request
+
+## Publish package
+
+<aside class="notice">

+  -XPOST \
+  -T tuxedo-keyboard-3.0.10-1-x86_64.pkg.tar.zst \
+  https://example.com/some-repo/publish
+```
+
+This endpoint allows you to publish a new package archive to a given repo.
+
+If the package's architecture is not `any`, it is added to that specific
+arch-repo. Otherwise, it is added to the configured default architecture & any
+other already present arch-repos.
+
+### HTTP Request
+
+`POST /:repo/publish`

+### URL Parameters
+

+`DELETE /:repo/:arch/:pkg`
+
+### URL Parameters
+
+Parameter | Description
+--------- | -----------
+repo | Repository to delete package from

+
+Welcome to the Vieter API documentation! Here, you can find everything related
+to interacting with Vieter's HTTP API.
+
+# Authentication
+
+```shell
+curl -H 'X-Api-Key: secret' https://example.com/api/some/path
+```
+
+> Don't forget to replace `secret` with your Vieter instance's secret.
+
+Authentication is done by passing the HTTP header `X-Api-Key: secret` along
+with each request, where `secret` is replaced with your Vieter server's
+configured secret.

+ * jQuery Highlight plugin
+ *
+ * Based on highlight v3 by Johann Burkard
+ * http://johannburkard.de/blog/programming/javascript/highlight-javascript-text-higlighting-jquery-plugin.html
+ *
+ * Code a little bit refactored and cleaned (in my humble opinion).
+ * Most important changes:
+ *  - has an option to highlight only entire words (wordsOnly - false by default),
+ *  - has an option to be case sensitive (caseSensitive - false by default)
+ *  - highlight element tag and class names can be specified in options
+ *
+ * Usage:
+ *   // wrap every occurrance of text 'lorem' in content
+ *   // with <span class='highlight'> (default options)
+ *   $('#content').highlight('lorem');
+ *
+ *   // search for and highlight more terms at once
+ *   // so you can save some time on traversing DOM
+ *   $('#content').highlight(['lorem', 'ipsum']);
+ *   $('#content').highlight('lorem ipsum');
+ *
+ *   // search only for entire word 'lorem'

+# Vieter
+
+{{< hint warning >}}
+**Important**  
+Because this project is still in heavy development, this documentation tries to
+follow the development branch & not the latest release. This means that the
+documentation might not be relevant anymore for the latest release.
+{{< /hint >}}
+
+## Overview
+
+Vieter consists of two main parts, namely an implementation of an Arch
+repository server & a scheduling system to periodically build Pacman packages &
+publish them to a repository.
+
+{{< hint info >}}
+**Note**  
+While I mention Vieter being an "Arch" repository server, it works with any
+distribution that uses Pacman as the package manager. I do recommend using a
+base docker image for your distribution if you wish to use the build system as
+well.
+{{< /hint >}}
+
+### Why?
+
+Vieter is my personal solution to a problem I've been facing for months:
+extremely long AUR package build times. I run EndeavourOS on both my laptops,
+one of which being a rather old MacBook Air. I really like being a beta-tester
+for projects & run development builds for multiple packages (nheko,
+newsflash...). Because of this, I have to regularly re-build these packages in
+order to stay up to date with development. However, these builds can take a
+really long time on the old MacBook. This project is a solution to that
+problem: instead of building the packages locally, I can build them
+automatically in the cloud & just download them whenever I update my system!
+Thanks to this solution, I'm able to shave 10-15 minutes off my update times,
+just from not having to compile everything every time there's an update.
+
+Besides this, it's also just really useful to have a repository server that you
+control & can upload your own packages to. For example, I package my st
+terminal using a CI pipeline & upload it to my repository!
+
+### Why V?
+
+I had been interested in learning V for a couple of months ever since I
+stumbled upon it by accident. It looked like a promising language & turned out
+to be very fun to use! It's fast & easy to learn, & it's a nice contrast with
+my usual Rust-based projects, which tend to get quite complex.
+
+I recommend checking out their [homepage](https://vlang.io/)!
+
+### What's with the name?
+
+Before deciding to write this project in V, I wrote a prototype in Python,
+called [Pieter](https://git.rustybever.be/Chewing_Bever/pieter). The name
+Pieter came from Pieter Post, the Dutch name for [Postname
+Pat](https://en.wikipedia.org/wiki/Postman_Pat). The idea was that the server
+"delivered packages", & a good friend of mine suggested the name. When I
+decided to switch over to Vieter, I changed the P (for Python) to a V, it
+seemed fitting.

+# Configuration
+
+By default, all vieter commands try to read in the TOML file `~/.vieterrc` for
+configuration. The location of this file can be changed by using the `-f` flag.
+
+If the above file doesn't exist or you wish to override some of its settings,
+configuration is also possible using environment variables. Every variable in
+the config file has a respective environment variable of the following form:
+say the variable is called `api_key`, then the respective environment variable
+would be `VIETER_API_KEY`. In essence, it's the variable in uppercase prepended
+with `VIETER_`.
+
+If a variable is both present in the config file & as an environment variable,
+the value in the environment variable is used.
+
+{{< hint info >}}
+**Note**
+All environment variables can also be provided from a file by appending them
+with `_FILE`. This for example allows you to provide the API key from a Docker
+secrets file.
+{{< /hint >}}
+
+## Commands
+
+The first argument passed to Vieter determines which command you wish to use.
+Each of these can contain subcommands (e.g. `vieter targets list`), but all
+subcommands will use the same configuration. Below you can find the
+configuration variable required for each command.
+
+### `vieter server`
+
+* `port`: HTTP port to run on
+    * Default: `8000`
+* `log_level`: log verbosity level. Value should be one of `FATAL`, `ERROR`,
+  `WARN`, `INFO` or `DEBUG`.
+    * Default: `WARN`
+* `pkg_dir`:  where Vieter should store the actual package archives.
+* `data_dir`: where Vieter stores the repositories, log file & database.
+* `api_key`: the API key to use when authenticating requests.
+* `default_arch`: this setting serves two main purposes:
+    * Packages with architecture `any` are always added to this architecture.
+      This prevents the server from being confused when an `any` package is
+      published as the very first package for a repository.
+    * Targets added without an `arch` value use this value instead.
+* `global_schedule`: build schedule for any target that does not have a
+  schedule defined. For information about this syntax, see
+  [here](/usage/builds/schedule).
+    * Default: `0 3` (3AM every night)
+* `base_image`: Docker image to use when building a package. Any Pacman-based
+  distro image should work, as long as `/etc/pacman.conf` is used &
+  `base-devel` exists in the repositories. Make sure that the image supports
+  the architecture of your cron daemon.
+    * Default: `archlinux:base-devel` (only works on `x86_64`). If you require
+      `aarch64` support, consider using
+      [`menci/archlinuxarm:base-devel`](https://hub.docker.com/r/menci/archlinuxarm)
+      ([GitHub](https://github.com/Menci/docker-archlinuxarm)). This is the
+      image used for the Vieter CI builds.
+* `max_log_age`: maximum age of logs (in days). Logs older than this will get
+  cleaned by the log removal daemon. If set to zero, no logs are ever removed.
+  The age of logs is determined by the time the build was started.
+    * Default: `0`
+* `log_removal_schedule`: cron schedule defining when to clean old logs.
+    * Default: `0 0` (every day at midnight)
+
+### `vieter cron`
+
+* `log_level`: log verbosity level. Value should be one of `FATAL`, `ERROR`,
+  `WARN`, `INFO` or `DEBUG`.
+    * Default: `WARN`
+* `log_file`: log file to write logs to.
+    * Default: `vieter.log` (in `data_dir`)
+* `address`: *public* URL of the Vieter repository server to build for. From
+  this server the list of Git repositories is retrieved. All built packages are
+  published to this server.
+* `api_key`: API key of the above server.
+* `data_dir`: directory to store log file in.
+* `base_image`: Docker image to use when building a package. Any Pacman-based
+  distro image should work, as long as `/etc/pacman.conf` is used &
+  `base-devel` exists in the repositories. Make sure that the image supports
+  the architecture of your cron daemon.
+    * Default: `archlinux:base-devel` (only works on `x86_64`). If you require
+      `aarch64` support, consider using
+      [`menci/archlinuxarm:base-devel`](https://hub.docker.com/r/menci/archlinuxarm)
+      ([GitHub](https://github.com/Menci/docker-archlinuxarm)). This is the image
+      used for the Vieter CI builds.
+* `max_concurrent_builds`: how many builds to run at the same time.
+    * Default: `1`
+* `api_update_frequency`: how frequently (in minutes) to poll the Vieter
+  repository server for a new list of Git repositories to build.
+    * Default: `15`
+* `image_rebuild_frequency`: Vieter periodically builds a builder image using
+  the configured base image. This makes sure build containers do not have to
+  download a lot of packages when updating their system. This setting defines
+  how frequently (in minutes) to rebuild this builder image.
+    * Default: `1440` (every 24 hours)
+* `global_schedule`: build schedule for any Git repository that does not have a
+  schedule defined. For information about this syntax, see
+  [here](/usage/builds/schedule).
+    * Default: `0 3` (3AM every night)
+
+### `vieter logs`
+
+* `api_key`: the API key to use when authenticating requests.
+* `address`: Base URL of your Vieter instance, e.g. https://example.com
+
+### `vieter targets`
+
+* `api_key`: the API key to use when authenticating requests.
+* `address`: Base URL of your Vieter instance, e.g. https://example.com
+* `base_image`: image to use when building a package using `vieter targets
+  build`.
+    * Default: `archlinux:base-devel`
+
+### `vieter agent`
+
+* `log_level`: log verbosity level. Value should be one of `FATAL`, `ERROR`,
+  `WARN`, `INFO` or `DEBUG`.
+    * Default: `WARN`
+* `address`: *public* URL of the Vieter repository server to build for. From
+  this server jobs are retrieved. All built packages are published to this
+  server.
+* `api_key`: API key of the above server.
+* `data_dir`: directory to store log file in.
+* `max_concurrent_builds`: how many builds to run at the same time.
+    * Default: `1`
+* `polling_frequency`: how often (in seconds) to poll the server for new
+  builds. Note that the agent might poll more frequently when it's actively
+  processing builds.
+* `image_rebuild_frequency`: Vieter periodically builds images that are then
+  used as a basis for running build containers. This is to prevent each build
+  from downloading an entire repository worth of dependencies. This setting
+  defines how frequently (in minutes) to rebuild these images.
+    * Default: `1440` (every 24 hours)
+* `arch`: architecture for which this agent should pull down builds (e.g.
+  `x86_64`)

+# Installation
+
+Vieter consists of a single binary, akin to busybox. The binary's behavior is
+determined by its CLI arguments, e.g. `vieter server` starts the repository
+server.
+
+All installation solutions can be configured the same way,
+as described [here](/configuration).
+
+## Docker
+
+Docker images are published to the
+[`chewingbever/vieter`](https://hub.docker.com/r/chewingbever/vieter) Docker
+Hub repository. You can either pull a release tag (e.g.
+`chewingbever/vieter:0.1.0-rc1`), or pull the `chewingbever/vieter:dev` tag.
+The latter is updated every time a new commit is pushed to the development
+branch. This branch will be the most up to date, but does not give any
+guarantees about stability, so beware!
+
+Thanks to the single-binary design of Vieter, this image can be used both for
+the repository server, the cron daemon and the agent.
+
+Below is a minimal compose file to set up both the repository server & a build
+agent:
+
+```yaml
+version: '3'
+
+services:
+  server:
+    image: 'chewingbever/vieter:0.5.0-rc.1'
+    restart: 'always'
+
+    environment:
+      - 'VIETER_API_KEY=secret'
+      - 'VIETER_DEFAULT_ARCH=x86_64'
+    volumes:
+      - 'data:/data'
+
+  cron:
+    image: 'chewingbever/vieter:0.5.0-rc.1'
+    restart: 'always'
+    # Required to connect to the Docker daemon
+    user: root
+    command: 'vieter agent'
+
+    environment:
+      - 'VIETER_API_KEY=secret'
+      # MUST be public URL of Vieter repository
+      - 'VIETER_ADDRESS=https://example.com'
+      # Architecture for which the agent builds
+      - 'VIETER_ARCH=x86_64'
+      - 'VIETER_MAX_CONCURRENT_BUILDS=2'
+    volumes:
+      - '/var/run/docker.sock:/var/run/docker.sock'
+
+volumes:
+  data:
+```
+
+If you do not require the build system, the repository server can be used
+independently as well.
+
+Of course, Vieter allows a lot more configuration than this. This compose file
+is meant as a starting point for setting up your installation.
+
+{{< hint info >}}
+**Note**  
+Builds are executed on the agent's system using the host's Docker daemon. An
+agent for a specific `arch` will only build packages for that specific
+architecture. Therefore, if you wish to build packages for both `x86_64` &
+`aarch64`, you'll have to deploy two agents, one on each architecture.
+Afterwards, any Git repositories enabled for those two architectures will build
+on both.
+{{< /hint >}}
+
+## Binary
+
+On the
+[releases](https://git.rustybever.be/vieter-v/vieter/releases)
+page, you can find statically compiled binaries for all
+released versions. This is the same binary as used inside
+the Docker images.
+
+## Arch
+
+I publish both development & release versions of Vieter to my personal
+repository, https://arch.r8r.be. Packages are available for `x86_64` &
+`aarch64`. To use the repository, add the following to your `pacman.conf`:
+
+```
+[vieter]
+Server = https://arch.r8r.be/$repo/$arch
+SigLevel = Optional
+```
+
+Afterwards, you can update your system & install the `vieter` package for the
+latest official release or `vieter-git` for the latest development release.
+
+### AUR
+
+If you prefer building the packages locally (or on your own Vieter instance),
+there's the [`vieter`](https://aur.archlinux.org/packages/vieter) &
+[`vieter-git`](https://aur.archlinux.org/packages/vieter-git) packages on the
+AUR. These packages build using the `vlang` compiler package, so I can't
+guarantee that a compiler update won't temporarily break them.
+
+## Building from source
+
+The project [README](https://git.rustybever.be/vieter-v/vieter#building)
+contains instructions for building Vieter from source.

+# Building packages
+
+The automatic build system is what makes Vieter very useful as a replacement
+for an AUR helper. It can perodically build packages & publish them to your
+personal Vieter repository server, removing the need to build the packages
+locally.
+
+## Adding builds
+
+Before the cron system can start building your package, you need to add its
+info to the system. The Vieter repository server exposes an HTTP API for this
+(see the [HTTP API Docs](https://rustybever.be/docs/vieter/api/) for more
+info). For ease of use, the Vieter binary contains a CLI interface for
+interacting with this API (see [Configuration](/configuration) for
+configuration details). The [man
+pages](https://rustybever.be/man/vieter/vieter-targets.1.html) describe this in
+greater detail, but the basic usage is as follows:
+
+```
+vieter targets add some-url some-repository
+```
+
+Here, `some-url` is the URL of the Git repository containing the PKGBUILD. This
+URL is passed to `git clone`, meaning the repository should be public. Vieter
+expects the same format as an AUR Git repository, so you can directly use AUR
+URLs here. Alternatively, you can also provide the URL to a PKGBUILD file
+instead. See
+[vieter-targets-add(1)](https://rustybever.be/man/vieter/vieter-targets-add.1.html)
+for more information.
+
+`some-repo` is the repository to which the built package archives should be
+published.
+
+The above command intentionally leaves out a few parameters to make the CLI
+more useable. For information on how to modify all parameters using the CLI,
+see
+[vieter-targets(1)](https://rustybever.be/man/vieter/vieter-targets.1.html).
+
+## Reading logs
+
+The logs of each build are uploaded to the Vieter repository server, along with
+information about the exit code of the build container, when the build
+started/ended etc. These logs can then be accessed using the [HTTP
+API](https://rustybever.be/docs/vieter/api/).
+
+For ease of use, the logs are also available using some CLI commands; see
+[vieter-logs(1)](https://rustybever.be/man/vieter/vieter-logs.1.html) for more
+information.

+
+# Cleanup
+
+Vieter stores the logs of every single package build. While this is great for
+debugging why builds fail, it also causes an active or long-running Vieter
+instance to accumulate thousands of logs.
+
+To combat this, a log removal daemon can be enabled that periodically removes
+old build logs. By starting your server with the `max_log_age` variable (see
+[Configuration](/configuration#vieter-server)), a daemon will get enabled that
+periodically removes logs older than this setting. By default, this will happen
+every day at midnight, but this behavior can be changed using the
+`log_removal_schedule` variable.
+
+{{< hint info >}}
+**Note**  
+The daemon will always run a removal of logs on startup. Therefore, it's
+possible the daemon will be *very* active when first enabling this setting.
+After the initial surge of logs to remove, it'll calm down again.

+# Cron schedule syntax
+
+The Vieter cron daemon uses a subset of the cron expression syntax to schedule
+builds.
+
+## Format
+
+`a b c d`
+
+* `a`: minutes
+* `b`: hours
+* `c`: days
+* `d`: months
+
+An expression consists of two to four sections. If less than four sections are
+provided, the parser will append `*` until there are four sections. This means
+that `0 3` is the same as `0 3 * *`.
+
+Each section consists of one or more parts, separated by a comma. Each of these
+parts, in turn, can be one of the following (any letters are integers):
+
+* `*`: allow all possible values.
+* `a`: only this value is allowed.
+* `*/n`: allow every n-th value.
+* `a/n`: allow every n-th value, starting at a in the list.
+* `a-b`: allow every value between a and b, bounds included.
+* `a-b/n`: allow every n-th value inside the list of values between a and b,
+  bounds included.
+
+Each section can consist of as many of these parts as necessary.
+
+## Examples
+
+* `0 3`: every day at 03:00AM.
+* `0 0 */7`: every 7th day of the month, at midnight.
+
+## CLI tool
+
+The Vieter binary contains a command that shows you the next matching times for
+a given expression. This can be useful for understanding the syntax. For more
+information, see
+[vieter-schedule(1)](https://rustybever.be/man/vieter/vieter-schedule.1.html).

+# Pacman repository
+
+The part of Vieter that users will interact with the most is the Pacman
+repository aka `vieter server`.
+
+## Design overview
+
+A Vieter repository server has support for multiple repositories, with each
+repository containing packages for multiple architectures.
+
+If you wish to use these repositories on your system, add the following to
+`/etc/pacman.conf` for each repository you wish to use:
+
+```
+[repo-name]
+Server = https://example.com/$repo/$arch
+SigLevel = Optional
+```
+
+Here, `$repo` and `$arch` are not variables you have to fill in yourself.
+Rather, Pacman will substitute these when reading the config file. `$repo` is
+replaced by the name between the square brackets (in this case `repo-name`),
+and `$arch` is replaced by your system's architecture, e.g. `x86_64`. Of
+course, you can also fill in these values manually yourself, e.g. if you wish
+to use a different name inside the square brackets.
+
+Important to note is that, when two repositories contain a package with the
+same name, Pacman will choose the one from the repository that's highest up in
+the `pacman.conf` file. Therefore, if you know your repository has packages
+with the same name as ones from the official repositories, it might be better
+to place the repository below the official repositories to avoid overwriting
+official packages.
+
+## Publishing packages
+
+Packages can be easily published using a single HTTP POST request. Check out
+the [HTTP API docs](https://rustybever.be/docs/vieter/api/) for more info on
+these routes, including example cURL commands.
