-To establish a unified style language throughout Alliance Auth and Community Apps,
-Alliance Auth is providing its own CSS framework with a couple of CSS classes.
+This section contains information about the Alliance Auth framework and how to use it.
+
+The Alliance Auth framework is a collection of reusable Python code as well as CSS classes

+
+The Alliance Auth framework is split into several submodules, each of which is documented in its own section.

 # Alliance Auth Helper-Functions API
 
+The following helper-functions are available in the `allianceauth.framework.api` module.
+They are intended to be used in Alliance Auth itself as well as in the community apps.
+
+These functions are intended to make the life of our community apps developer a little
+easier, so they don't have to reinvent the wheel all the time.

+## EveCharacter API
+
+### get_main_character_from_evecharacter
+
+This is to get the main character object (`EveCharacter`) of an `EveCharacter` object.
+
+Given we have an `EveCharacter` object called `my_evecharacter` and we want to get the main character:
+
+```python
+# Alliance Auth
+from allianceauth.framework.api.evecharacter import get_main_character_from_evecharacter
+
+main_character = get_main_character_from_evecharacter(character=my_evecharacter)
+```
+
+Now, `main_character` is an `EveCharacter` object, or `None` if the `EveCharacter` has no main character.
+
+### get_user_from_evecharacter
+
+This is to get the user object (`User`) of an `EveCharacter` object.
+
+Given we have an `EveCharacter` object called `my_evecharacter` and we want to get the user:
+
+```python
+# Alliance Auth
+from allianceauth.framework.api.evecharacter import get_user_from_evecharacter
+
+user = get_user_from_evecharacter(character=my_evecharacter)
+```
+
+Now, `user` is a `User` object, or the sentinel username (see [get_sentinel_user](#get-sentinel-user))
+if the `EveCharacter` has no user.
+
 ## User API
 
+### get_all_characters_from_user
+
+This is to get all character objects (`EveCharacter`) of a user.
+
+Given we have a `User` object called `my_user` and we want to get all characters:
+
+```python
+# Alliance Auth
+from allianceauth.framework.api.user import get_all_characters_from_user
+
+characters = get_all_characters_from_user(user=my_user)
+```
+
+Now, `characters` is a `list` containing all `EveCharacter` objects of the user.
+If the user is `None`, an empty `list` will be returned.
