 You can use [this script](https://github.com/pytition/Pytition/blob/master/dev/dev_setup.sh) to setup a development environment.

 This script is only proven to work on a fresh Ubuntu 18.04 install.
 You can use VirtualBox, Docker, qemu or whatever virtualisation/containerization technology you prefer.
 
-### Manual
-
-If you don't trust the above script, and don't want to use Docker, you can install Pytition manually.
-We will use MariaDB as a backend. If you prefer PostgreSQL or SQlite, try with the automatic script or with Docker.
 
-First, you'll need to clone the repository:
-```bash
-git clone [email protected]:pytition/Pytition.git
-# or, if you prefer HTTPS
-git clone https://github.com/pytition/Pytition.git
-```
-Then you will need native dependencies:
-```bash
-# On Debian and derivatives
-sudo apt update
-sudo apt install git virtualenv libmariadbclient-dev python3-dev build-essential mariadb-server
-# If you use Yum/DNF
-sudo yum install MariaDB-server galera-4 MariaDB-client MariaDB-shared MariaDB-backup MariaDB-common git python3 python3-virtualenv make gcc
-# On Arch
-sudo pacman -S mariadb mariadb-libs python make gcc
-```
-Move in the freshly cloned directory with `cd Pytition`, and create a VirtualEnv.
-It will isolate your Python setup for Pytition from the rest of your system, avoiding packages conflicts for other projects.
-```
-virtualenv -p python3 venv
-# You can enter in the virtualenv with:
-source venv/bin/activate
-```
-You will need to run this last command every time you start working on Pytition.
-You can now install Python packages:
-```
-pip3 install -r requirements_dev.txt
-```
-Init the database with:
-```bash
-password="ENTER_A_SECURE_PASSWORD_YOU_WILL_REMEMBER_HERE"
-sudo mysql -h localhost -u root -Bse "CREATE USER pytition@localhost IDENTIFIED BY '${password}'; CREATE DATABASE pytition; GRANT USAGE ON *.* TO 'pytition'@localhost IDENTIFIED BY '${password}'; GRANT ALL privileges ON pytition.* TO pytition@localhost; FLUSH PRIVILEGES;"
-```
-Then write the following in a new file called `my.cnf`:
-```
-[client]
-database = pytition
-user = pytition
-password = YOUR_PASSWORD_HERE
-default-character-set = utf8
-```
-Tell Pytition where to find this file with:
-```bash
-sed -i -e "s@/home/petition/www/@$PWD/@" pytition/pytition/settings/base.py
-```
-Then run migrations (scripts to initialize the database):
-```bash
-cd pytition && python3 ./manage.py migrate && cd -
-```
-You can create an administrator account, and populate the database with fake data:
-```bash
-cd pytition && python3 ./manage.py createsuperuser && cd -
-./dev/prepropulate.sh
-```
-And… you are done! You can start the server with:
-```bash
-python3 ./pytition/manage.py runserver
-```
-You can access it at [http://localhost:8080](http://localhost:8080)!
-### With docker-compose
-This creates two containers, one for the database using postgresql, another for the django project.
-```
-docker-compose up --build
-docker-compose exec web ./dev/initialize.sh
-```
-This script will
-* Run database migration
-* Create superuser account
-* Insert data into the development database
