-## Useful commands
-
-* `./manage.py import-vat-rates path/to/csv`
-* `./manage.py createsuperuser`
-
-## Development setup
-
-Install system dependencies:
-
-* On Fedora, you will need the following packages: `python3-virtualenv python3-devel openldap-devel gcc chromium`
-* sudo apt-get install libpq-dev python-dev libxml2-dev libxslt1-dev libldap2-dev libsasl2-dev libffi-dev
-* On Archlinux, [libldap24](https://aur.archlinux.org/packages/libldap24) is needed
-
-
-NOTE: you will need to configure a LDAP server and credentials for authentication. See `uncloud/settings.py`.
-
-```
-# Initialize virtualenv.
-» virtualenv .venv
-Using base prefix '/usr'
-New python executable in /home/fnux/Workspace/ungleich/uncloud/uncloud/.venv/bin/python3
-Also creating executable in /home/fnux/Workspace/ungleich/uncloud/uncloud/.venv/bin/python
-Installing setuptools, pip, wheel...

-Django version 3.0.6, using settings 'uncloud.settings'
-Starting development server at http://127.0.0.1:8000/
-Quit the server with CONTROL-C.
-```
-### Run Background Job Queue
-We use Django Q to handle the asynchronous code and Background Cron jobs
-To start the workers make sure first that Redis or the Django Q broker is working and you can edit it's settings in the settings file.
-```
-./manage.py qcluster
-```
-
-### Note on PGSQL
-
-If you want to use Postgres:
-
-* Install on configure PGSQL on your base system.
-* OR use a container! `podman run --rm -p 5432:5432 -e POSTGRES_HOST_AUTH_METHOD=trust -it postgres:latest`
