+Flaschengeist provides a CLI, based on the flask CLI, respectivly called `flaschengeist`.
+
+⚠️ When using the CLI for running Flaschengeist, please note that logging will happen as configured,
+with the difference of the main logger will be forced to output to `stderr` and the logging level
+of the CLI will override the logging level you have configured for the main logger.

+# Plugin Development
+
+## File Structure
+
+    - your_plugin/
+        - __init__.py
+        - ...
+        - migrations/ (optional)
+            - ...
+    - setup.cfg
+
+The basic layout of a plugin is quite simple, you will only need the `setup.cfg` or `setup.py` and
+the package containing your plugin code, at lease a `__init__.py` file with your `Plugin` class.
+
+If you use custom database tables you need to provide a `migrations` directory within your package,
+see next section.
+
+## Database Tables / Migrations
+To allow upgrades of installed plugins, the database is versioned and handled
+through [Alembic](https://alembic.sqlalchemy.org/en/latest/index.html) migrations.
+Each plugin, which uses custom database tables, is represented as an other base.
+So you could simply follow the Alembic tutorial on [how to work with multiple bases](https://alembic.sqlalchemy.org/en/latest/branches.html#creating-a-labeled-base-revision).
+
+A quick overview on how to work with migrations for your plugin:
+
+    $ flaschengeist db revision -m "Create my super plugin" \
+      --head=base --branch-label=myplugin_name --version-path=your/plugin/migrations
+
+This would add a new base named `myplugin_name`, which should be the same as the pypi name of you plugin.
+If your tables depend on an other plugin or a specific base version you could of cause add
+
+    --depends-on=VERSION
+
+or
+
+    --depends-on=other_plugin
+
+
+### Plugin Removal and Database Tables
+As generic downgrades are most often hard to write, your plugin is not required to provide such functionallity.
+For Flaschengeist only instable versions provide meaningful downgrade migrations down to the latest stable version.
+
+So this means if you do not provide downgrades you must at lease provide a series of migrations toward removal of
+the database tables in case the users wants to delete the plugin.
+
+    (base) ----> 1.0 <----> 1.1 <----> 1.2
+                  |         
+                  --> removal
+
+After the removal step the database is stamped to to "remove" your
