 You bet. The time has come.
 
-## Development
+### Discord Documentation
 
-Didier uses `Python 3.9.5`, as specified in the [`.python-version`](.python-version)-file. This file will cause [`pyenv`](https://github.com/pyenv/pyenv) to automatically use the correct version when you're working on Didier.
+[Link to the Discord API docs](https://discordpy.readthedocs.io/en/latest/index.html). When making a command, make sure to check to docs to see if what you're doing is even possible, and if you're providing the right (amount of) parameters. Ask questions in De Zandbak Discord all you want, but at least make an attempt at looking it up first.
 
-```shell
-# Installing Python 3.9.5 through pyenv
-pyenv install 3.9.5
+### Running Didier
 
-# Creating a Virtual Environment and activate it
-# PyCharm will automatically activate your venv
-python3 -m venv venv
-source venv/bin/activate
+In order to run Didier, simply run `python3 didier.py` in your terminal, or click `run` in PyCharm (green arrow @ top-right, or right-click the file). Make sure you have installed all the required packages in `requirements.txt`.
 
-# Installing dependencies + development dependencies
-pip3 install -r requirements.txt -r requirements-dev.txt
+### Databases
 
-# Installing pre-commit hooks
-pre-commit install
+`databases.md` contains info on every database. Using this file you can find out which tables exist, which columns those tables have, and which types of values those columns contain. This should be enough for you to set up a local Postgresql database in order to mess around with & test functions before committing them (guilty).
+
+### Cog Template
+
+When using PyCharm, you can configure [file templates](https://www.jetbrains.com/help/pycharm/using-file-and-code-templates.html) to create blueprints for files. This speeds up the process of creating `Cogs` as you don't have to write the same exact code every single time.
+
+Below is the Cog template you are expected to use when creating new Cogs for Didier, providing both essential and commonly-used imports & functionality. It's possible that you don't need all of the imports, in which case you can obviously remove the obsolete ones.
+
+```python
+from data import constants
+import discord
+from discord.ext import commands
+from decorators import help
+from enums.help_categories import Category
+from functions import checks
+
+
+class Cog(commands.Cog):
+    def __init__(self, client):
+        self.client = client
+
+    # Don't allow any commands to work when locked
+    def cog_check(self, ctx):
+        return not self.client.locked
+
+def setup(client):
+    client.add_cog(Cog(client))
 ```
 
-The database can be managed easily using `Docker Compose`. If you want to, however, you can run a regular PostgreSQL server and connect to that instead.
+Replacing the classname `Cog` with the name of your cog.
 
-A separate database is used in the tests, as it would obviously not be ideal when tests randomly wipe your database.
+### Help Categories
 
-```shell
-# Starting the database
-docker-compose up -d db
+Didier uses a custom help command, which classifies certain commands into categories. Discord's default help does this based on `Cogs`, but this would mean some Cogs would be thousands of lines long, defeating the purpose of using them in the first place.
 
-# Starting the database used in tests
-docker-compose up -d db-pytest
+When creating a new Didier command, you can add it to a `Category` by adding a decorator above the function. The example below shows how to add a command to the `Currency` category.
+
+```python
+from decorators import help
+from discord.ext import commands
+from enums.help_categories import Category
+from functions import checks
+
+@commands.command(name="Command Name", aliases=["Cn"])
+@commands.check(checks.allowedChannels)
+@help.Category(Category.Currency)
+async def command_name(self, ctx):
+    # Command code
+    await ctx.send("Command response")
 ```
 
-### Commands
+This allows commands across multiple Cogs to be classified under the same category in the help page.
 
-```shell
-# Starting Didier
-python3 main.py
+### Python Version
+Didier uses `Python 3.9.5`, the most recent one as of the writing of this sentence. The reasoning behind this is that I hope it'll last for a while so I don't have to update it all the time.
 
-# Running tests
-pytest
+### Ignored Files
+`ignored.md` contains a list of all ignored files, and what they look like. This way, you can recreate these files locally to test commands that use them. API keys should be stored in `environment variables`. To do so, create a file called `.env` in the root of this repository (which has already been added to `.gitignore`) and make sure the names match.
 
-# Running tests with Coverage
-coverage run -m pytest
-# Generating code coverage report
-coverage html
+### FAQ
+`faq.md` is always worth taking a look at when you've got a question. Right now this doesn't contain much, as I don't have any questions for myself, but over time this will be expanded upon.
 
-# Running code quality checks
-black
-flake8
-mypy
-```
+### Useful Links
+- [Embed Visualizer](https://leovoel.github.io/embed-visualizer/): Allows for easy creation of embeds, and can generate the code for them (bottom: "Generate Code" -> "discord.py (Python)"). This is helpful when starting out so you can see what you're doing, when you don't really know how Embeds work yet.
