-### Quick start
-
-It assumes that you already have the application source code locally - the best
-way is by cloning this repository - and that you are in this folder.
-
-1.  Define your local configuration in a file named `config.env`, which can be
-    copied from `config.env.example` and edited to suits your needs.
-
-    Depending on your environment, you will have to create your database and the
-    user at first.
-
-2.  Run `make init`.
-
-    Note that if there is no `config.env` file, it will be created interactively.
-
-That's it! Your environment is now initialized with the application installed.
-To update it, once the source code is checked out, simply run `make update`.
-
-You can also check that your application is well configured by running
-`make check`.
-
-### Manual installation
-
-If you don't want to use the `Makefile` facilities, here is what is done behind the scene.
-
-It assumes that you have downloaded the last release of drupal2spip_lal,
-extracted it and that you moved to that folder.
-
-1.  Start by creating a new virtual environment under `./venv` and activate it:
-
-        $ virtualenv --system-site-packages ./venv
-        $ source ./venv/bin/activate
-
-2.  Install the required Python packages depending on your environment:
-
-        $ pip install -r requirements/production.txt
-        ... or ...
-        $ pip install -r requirements/development.txt
-
-3.  Configure the application by setting the proper environment variables
-    depending on your environment. You can use the `config.env.example` which
-    give you the main variables with example values.
-
-        $ cp config.env.example config.env
-        $ nano config.env
-        $ chmod go-rwx config.env
-
-    Note that this `./config.env` file will be loaded by default when the
-    application starts. If you don't want that, just move this file away or set
-    the `READ_CONFIG_FILE` environment variable to `0`.
-
-4.  Create the database tables - it assumes that you have created the database
-    and set the proper configuration to use it:
-
-        $ ./manage.py migrate
+See:
+```
+$ venv/bin/python manage.py import --help
+```
 
 That's it!
