 # Requirements
-- A working postgresql setup
-- A working redis setup
-- python3.7
+- A GNU/Linux OS
+- python>=3.9 (see Pipfile for up to date info)
+
+## Pipenv
+
+Pipenv is a python virtualenv and dependency manager.
+
+If you do not already have `pipenv` installed:
+```sh
+# Arch-based linux (Arch, Manjaro, ...)
+sudo pacman -S python-pipenv
+
+# Debian-based (Debian, Ubuntu, ...)
+sudo apt install pipenv
+```
+For other distros, see https://pkgs.org/search/?q=pipenv
+Or do `pip install --user pipenv`
 
-# Installation
 ## Database
 
-To create a postgresql database, use:
+By default, it uses a sqlite database located at `/db.sqlite3` which is ignored by git.
+
+This is not the production setup, so some DB checks may not be done.
+As the CI runs with the same engine as production (PostgreSQL), this is not critical if
+you do your unit tests right.
+
+## Redis
+
+Unfortunately, a redis server is required even for development purposes.
+This may change in the future, allowing for easier dev setup with no caching.
+
+### Arch-based
+
+From https://wiki.archlinux.org/title/Redis#Installation
+
+```sh
+sudo pacman -S redis
+sudo systemctl enable --now redis.service
+```
+
+### Debian
+
+The following line installs and starts redis
+```sh
+sudo apt install redis-server
 ```
-createdatabase -O dbOwner dbName
+
+### Ubuntu
+
+Follow step 1 from this tutorial: https://www.digitalocean.com/community/tutorials/how-to-install-and-secure-redis-on-ubuntu-18-04
+
+## CSS compiler
+
+This is only needed if you intend to edit the CSS.
+
+We are using Sass to mimimize the file loads required.
+
+You will need `sassc` to use the provided makefile.
+
+```sh
+# Arch-based
+sudo pacman -S sassc
+
+# Debian-based
+sudo apt install sassc
 ```
 
+Then, once you have made your edits to the sass files, run `make css` and commit the sass and css.
+
+# Installation
+
+Once you have all requirements, you can run `make install`.
+It will install all python dependencies in a venv and migrate the database.
 
 ## Venv
+If you want to do it manually
 ```
 pipenv sync --dev
 ```
 
 ## Migrations
+If you want to do it manually
 ```
 pipenv shell
 manage.py migrate
