+# 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 -OL 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 -IL 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">
+
+This endpoint requests authentication.
+
+</aside>
+
+```shell
+curl \
+  -H 'X-Api-Key: secret' \
+  -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
+
+Parameter | Description
+--------- | -----------
+repo | Repository to publish package to

+# Introduction
+
+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'
+ *   $('#content').highlight('lorem', { wordsOnly: true });
+ *
+ *   // don't ignore case during search of term 'lorem'
+ *   $('#content').highlight('lorem', { caseSensitive: true });
+ *
+ *   // wrap every occurrance of term 'ipsum' in content
+ *   // with <em class='important'>
+ *   $('#content').highlight('ipsum', { element: 'em', className: 'important' });
+ *
+ *   // remove default highlight
+ *   $('#content').unhighlight();
+ *
+ *   // remove custom highlight
+ *   $('#content').unhighlight({ element: 'em', className: 'important' });

+/**
+ * Although lunr provides the ability to create queries using lunr.Query, it also provides a simple
+ * query language which itself is parsed into an instance of lunr.Query.
+ *
+ * For programmatically building queries it is advised to directly use lunr.Query, the query language
+ * is best used for human entered text rather than program generated text.
+ *
+ * At its simplest queries can just be a single term, e.g. `hello`, multiple terms are also supported
+ * and will be combined with OR, e.g `hello world` will match documents that contain either 'hello'
+ * or 'world', though those that contain both will rank higher in the results.
+ *
+ * Wildcards can be included in terms to match one or more unspecified characters, these wildcards can
+ * be inserted anywhere within the term, and more than one wildcard can exist in a single term. Adding
+ * wildcards will increase the number of documents that will be found but can also have a negative
+ * impact on query performance, especially with wildcards at the beginning of a term.
+ *
+ * Terms can be restricted to specific fields, e.g. `title:hello`, only documents with the term
+ * hello in the title field will match this query. Using a field not present in the index will lead
+ * to an error being thrown.
+ *
+ * Modifiers can also be added to terms, lunr supports edit distance and boost modifiers on terms. A term
+ * boost will make documents matching that term score higher, e.g. `foo^5`. Edit distance is also supported
+ * to provide fuzzy matching, e.g. 'hello~2' will match documents with hello with an edit distance of 2.
+ * Avoid large values for edit distance to improve query performance.
+ *
+ * Each term also supports a presence modifier. By default a term's presence in document is optional, however
+ * this can be changed to either required or prohibited. For a term's presence to be required in a document the
+ * term should be prefixed with a '+', e.g. `+foo bar` is a search for documents that must contain 'foo' and
+ * optionally contain 'bar'. Conversely a leading '-' sets the terms presence to prohibited, i.e. it must not
+ * appear in a document, e.g. `-foo bar` is a search for documents that do not contain 'foo' but may contain 'bar'.
+ *
+ * To escape special characters the backslash character '\' can be used, this allows searches to include
+ * characters that would normally be considered modifiers, e.g. `foo\~2` will search for a term "foo~2" instead
+ * of attempting to apply a boost of 2 to the search term "foo".
+ *
+ * @typedef {string} lunr.Index~QueryString
+ * @example <caption>Simple single term query</caption>
+ * hello
+ * @example <caption>Multiple term query</caption>
+ * hello world
+ * @example <caption>term scoped to a field</caption>
+ * title:hello
+ * @example <caption>term with a boost of 10</caption>
+ * hello^10
+ * @example <caption>term with an edit distance of 2</caption>
+ * hello~2

+### 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/docs/vieter`
+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'll 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.

-# API Reference
-
-All routes that return JSON use the following shape:
-
-```json
-{
-    "message": "some message",
-    "data": {}
-}
-```
-
-Here, data can be any JSON object, so it's not guaranteed to be a struct.
-
-### `GET /<repo>/<arch>/<filename>`
-
-This route serves the contents of a specific architecture' repo.
-
-If `<filename>` is one of `<repo>.db`, `<repo>.files`, `<repo>.db.tar.gz` or
-`<repo>.files.tar.gz`, it will serve the respective archive file from the
-repository.
-
-If `<filename>` contains `.pkg`, it assumes the request to be for a package
-archive & will serve that file from the specific arch-repo's package directory.
-
-Finally, if none of the above are true, Vieter assumes it  to be request for a
-package version's desc file & tries to serve this instead. This functionality
-is very useful for the build system for checking whether a package needs to be
-rebuilt or not.
-
-### `HEAD /<repo>/<arch>/<filename>`
-
-Behaves the same as the above route, but instead of returning actual data, it
-returns either 200 or 404, depending on whether the file exists. This route is
-used by the build system to determine whether a package needs to be rebuilt.
-
-### `POST /<repo>/publish`
-
-This route is used to upload packages to a repository. It requires the API
-key to be provided using the `X-Api-Key` HTTP header. Vieter will parse the
-package's contents & update the repository files accordingely. I find the
-easiest way to use this route is using cURL:
-
-```sh
-curl -XPOST -T "path-to-package.pkg.tar.zst" -H "X-API-KEY: your-api-key" https://example.com/somerepo/publish
-```
-
-Packages are automatically added to the correct arch-repo. If a package type is
-`any`, the package is added to the configured `default_arch`, as well as all
-already present arch-repos. To prevent unnecessary duplication of package
-files, these packages are shared between arch-repos' package directories using
-hard links.
-
-{{< hint info >}}
-**Note**  
-Vieter only supports uploading archives compressed using either gzip, zstd or
-xz at the moment.
-{{< /hint >}}
-
-### `GET /health`
-
-This endpoint's only use is to be used with healthchecks. It returns a JSON
-response with the message "Healthy.".
-
-## API
-
-All API routes require the API key to provided using the `X-Api-Key` header.
-Otherwise, they'll return a status code 401.
-
-### `GET /api/repos`
-
-Returns the current list of Git repositories.
-
-### `GET /api/repos/<id>`
-
-Get the information for the Git repo with the given ID.
-
-### `POST /api/repos?<url>&<branch>&<arch>&<repo>`
-
-Adds a new Git repository with the provided URL, Git branch & comma-separated
-list of architectures.
-
-### `DELETE /api/repos/<id>`
-
-Deletes the Git repository with the provided ID.
-
-### `PATCH /api/repos/<id>?<url>&<branch>&<arch>&<repo>`
-
-Updates the provided parameters for the repo with the given ID. All arguments
-are optional.

 # 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 is the recommended way to install vieter. The images can be pulled from
-[`chewingbever/vieter`](https://hub.docker.com/r/chewingbever/vieter). 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!
+Docker images are published to the

+Hub repository. You can either pull a release tag (e.g.

+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!
 
-The simplest way to run the Docker image is using a plain Docker command:
+Due to the single-binary design of Vieter, this image can be used both for the
+repository server & the cron daemon.
 
-```sh
-docker run \
-    --rm \
-    -d \
-    -v /path/to/data:/data \
-    -e VIETER_API_KEY=changeme \
-    -e VIETER_DEFAULT_ARCH=x86_64 \
-    -p 8000:8000 \
-    chewingbever/vieter:dev
+Below is an example compose file to set up both the repository server & the
+cron daemon:
+
+```yaml
+version: '3'
+
+services:
+  server:
+    image: 'chewingbever/vieter:dev'
+    restart: 'always'
+
+    environment:
+      - 'VIETER_API_KEY=secret'
+      - 'VIETER_DEFAULT_ARCH=x86_64'
+    volumes:
+      - 'data:/data'
+
+  cron:
+    image: 'chewingbever/vieter:dev'
+    restart: 'always'
+    user: root
+    command: 'vieter cron'
+
+    environment:
+      - 'VIETER_API_KEY=secret'
+      # MUST be public URL of Vieter repository
+      - 'VIETER_ADDRESS=https://example.com'
+      - 'VIETER_DEFAULT_ARCH=x86_64'
+      - 'VIETER_MAX_CONCURRENT_BUILDS=2'
+      - 'VIETER_GLOBAL_SCHEDULE=0 3'
+
+volumes:
+  data:
 ```
 
-Here, you should change `/path/to/data` to the path on your host where you want
-vieter to store its files.
-
-The default configuration will store everything inside the `/data` directory.
-
-Inside the container, the Vieter server runs on port 8000. This port should be
-exposed to the public accordingely.
-
-For an overview of how to configure vieter & which environment variables can be
-used, see the [Configuration](/configuration) page.
-
 ## Binary
 
-On the [releases](https://git.rustybever.be/Chewing_Bever/vieter/releases)
-page, you can find statically compiled binaries for all released versions. You
-can download the binary for your host's architecture & run it that way.

-For more information about configuring the binary, check out the
-[Configuration](/configuration) page.
+## 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.
 
 ## Building from source
 
-Because the project is still in heavy development, it might be useful to build
-from source instead. Luckily, this process is very easy. You'll need make,
-libarchive & openssl; all of which should be present on an every-day Arch
-install. Then, after cloning the repository, you can use the following commands:
-
-```sh
-# Builds the compiler; should usually only be ran once. Vieter compiles using
-# the default compiler, but I maintain my own mirror to ensure nothing breaks
-# without me knowing.
-make v
-
-# Build vieter
-# Alternatively, use `make prod` to build the production build.
-make
-```
-{{< hint info >}}
-**Note**  
-My version of the V compiler is also available on my Vieter instance,
-https://arch.r8r.be. It's in the `vieter` repository, with the package being
-named `vieter-v`. The compiler is available for both x86_64 & aarch64.
-{{< /hint >}}
-
-## My Vieter instance
-
-Besides uploading development Docker images, my CI also publishes x86_64 &
-aarch64 packages to my personal Vieter instance, https://arch.r8r.be. If you'd
-like, you can use this repository as well by adding it to your Pacman
-configuration as described [here](/usage#configuring-pacman). Both the
-repository & the package are called `vieter`.
+The project [README](https://git.rustybever.be/vieter/vieter#building) contains
+instructions for building Vieter from source.

+# 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, `$repo` & `$arch` are not variables you have to fill in yourself. Rather,
+Pacman will substitute these when reading the config file. `$repo` is replaced
+by the name between the square brackets (in this case `repo-name`), & `$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.

+# 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-repos.1.html) describe this in
+greater detail, but the basic usage is as follows:
+
+```
+vieter repos add some-url some-branch some-repository
+```
+
+Here, `some-url` is the URL of the Git repository containing the PKGBUILD. This
+URL is passed to `git clone`, so the repository should be public. Vieter
+expects the same format as an AUR Git repository, so you can directly use AUR
+URLs here.
+
+`some-branch` is the branch of the Git repository the build should check out.
+If you're using an AUR package, this should be `master`.
+
+Finally, `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-repos-edit(1)](https://rustybever.be/man/vieter/vieter-repos-edit.1.html).

+# 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 to understand the syntax. For more
+information, see
+[vieter-schedule(1)](https://rustybever.be/man/vieter/vieter-schedule.1.html).

-# Vieter CLI
-
-I provide a simple CLI tool that currently only allows changing the Git
-repository API. Its usage is quite simple.
-
-First, you need to create a file in your home directory called `.vieterrc` with
-the following content:
-
-```toml
-address = "https://example.com"
-api_key = "your-api-key"
-```
-
-You can also use a different file or use environment variables, as described in
-[Configuration](/configuration).
-
-Now you're ready to use the CLI tool.
-
-## Usage
-
-* `vieter repos list` returns all repositories currently stored in the API.
-* `vieter repos add url branch repo arch...` adds the repository with the given
-  URL, branch, repo & arch to the API.
-* `vieter repos remove id` removes the repository with the given ID prefix.
-
-You can always check `vieter -help` or `vieter repos -help` for more
-information about the commands.

-# Usage
-
-## Starting the server
-
-To start a server, either install it using Docker (see
-[Installation](/installation)) or run it locally by executing `vieter
-server`. See [Configuration](/configuration) for more information about
-configuring the binary.
-
-## Multiple repositories
-
-Vieter works with multiple repositories. This means that a single Vieter server
-can serve multiple repositories in Pacman. It also automatically divides files
-with specific architectures among arch-repos. Arch-repos are the actual
-repositories you add to your `/etc/pacman.conf` file. See [Configuring
-Pacman](/usage#configuring-pacman) below for more info.
-
-## Adding packages
-
-Using Vieter is currently very simple. If you wish to add a package to Vieter,
-build it using makepkg & POST that file to the `/<repo>/publish` endpoint of
-your server. This will add the package to the repository. Authentification
-requires you to add the API key as the `X-Api-Key` header.
-
-All of this can be combined into a simple cURL call:
-
-```
-curl -XPOST -H "X-API-KEY: your-key" -T some-package.pkg.tar.zst https://example.com/somerepo/publish
-```
-
-`somerepo` is automatically created if it doesn't exist yet.
-
-## Configuring Pacman
-
-Configuring Pacman to use a Vieter instance is very simple. In your
-`/etc/pacman.conf` file, add the following lines:
-
-```
-[vieter]
-Server = https://example.com/$repo/$arch
-SigLevel = Optional
-```
-
-Here, you see two important placeholder variables. `$repo` is replaced by the
-name within the square brackets, which in this case would be `vieter`. `$arch`
-is replaced by the output of `uname -m`. Because Vieter supports multiple
-repositories & architectures per repository, using this notation makes sure you
-always use the correct endpoint for fetching files.
-
-I recommend placing this below all other repository entries, as the order
-decides which repository should be used if there's ever a naming conflict.

 For those interested, this page describes how the build system works
 internally.
+
+## Builder image
+
+Every cron daemon perodically creates a builder image that is then used as a
+base for all builds. This is done to prevent build containers having to pull
+down a bunch of updates when they update their system.
+
+The build container is created by running the following commands inside a
+container started from the image defined in `base_image`:
+
+```sh
+# Update repos & install required packages
+pacman -Syu --needed --noconfirm base-devel git
+# Add a non-root user to run makepkg
+groupadd -g 1000 builder
+useradd -mg builder builder
+# Make sure they can use sudo without a password
+echo 'builder ALL=(ALL) NOPASSWD: ALL' >> /etc/sudoers
+# Create the directory for the builds & make it writeable for the
+# build user
+mkdir /build
+chown -R builder:builder /build
+```
+
+This script updates the packages to their latest versions & creates a non-root
+user to use when running `makepkg`.
+
+This script is base64-encoded & passed to the container as an environment
+variable. The container's entrypoint is set to `/bin/sh -c` & its command
+argument to `echo $BUILD_SCRIPT | base64 -d | /bin/sh -e`, with the
+`BUILD_SCRIPT` environment variable containing the base64-encoded script.
+
+Once the container exits, a new Docker image is created from it. This image is
+then used as the base for any builds.
+
+## Running builds
+
+Each build has its own Docker container, using the builder image as its base.
+The same base64-based technique as above is used, just with a different script.
+To make the build logs more clear, each command is appended by an echo command
+printing the next command to stdout.
+
+Given the Git repository URL is `https://examplerepo.com` with branch `main`,
+the URL of the Vieter server is `https://example.com` and `vieter` is the
+repository we wish to publish to, we get the following script:
+
+```sh
+echo -e '+ echo -e '\''[vieter]\\nServer = https://example.com/$repo/$arch\\nSigLevel = Optional'\'' >> /etc/pacman.conf'
+echo -e '[vieter]\nServer = https://example.com/$repo/$arch\nSigLevel = Optional' >> /etc/pacman.conf
+echo -e '+ pacman -Syu --needed --noconfirm'

+```
+
+This script:
+
+1. Adds the target repository as a repository in the build container
+2. Updates mirrors & packages
+3. Clones the Git repository
+4. Runs `makepkg` without building to calculate `pkgver`
+5. Checks whether the package version is already present on the server

-# Builder
-
-Vieter supports a basic build system that allows you to build the packages
-defined using the Git repositories API by running `vieter build`. For
-configuration, see [here](/configuration#builder).
-
-## How it works
-
-The build system works in two stages. First it pulls down the
-`archlinux:latest` image from Docker Hub, runs `pacman -Syu` & configures a
-non-root build user. It then creates a new Docker image from this container.
-This is to prevent each build having to fully update the container's
-repositories. After the image has been created, each repository returned by
-`/api/repos` is built sequentially by starting up a new container with the
-previously created image as a base. Each container goes through the following steps:
-
-1. The repository is cloned
-2. `makepkg --nobuild --syncdeps --needed --noconfirm` is ran to update the `pkgver` variable inside
-   the `PKGBUILD` file
-3. A HEAD request is sent to the Vieter server to check whether the specific
-   version of the package is already present. If it is, the container exits.
-4. `makepkg` is ran with `MAKEFLAGS="-j\$(nproc)`
-5. Each produced package archive is uploaded to the Vieter instance's
-   repository, as defined in the API for that specific Git repo.
-
-## Cron image
-
-The Vieter Docker image contains crond & a cron config that runs `vieter build`
-every night at 3AM. This value is currently hardcoded, but I wish to change
-that down the line (work is in progress). There's also some other caveats you
-should be aware of, namely that the image should be run as root & that the
-healthcheck will always fail, so you might have to disable it. This boils down
-to the following docker-compose file:
-
-```yaml
-version: '3'
-
-services:
-  cron:
-    image: 'chewingbever/vieter:dev'
-    command: crond -f
-    user: root
-
-    healthcheck:
-      disable: true
-        
-    environment:
-      - 'VIETER_API_KEY=some-key'
-      - 'VIETER_ADDRESS=https://example.com'
-    volumes:
-      - '/var/run/docker.sock:/var/run/docker.sock'
-```
-
-Important to note is that the container also requires the host's Docker socket
-to be mounted as this is how it spawns the necessary containers, as well as a
-change to the container's command.
