+Documentation of available API endpoints.  
+**Note: This will change!**
+
+## Authentication
+API token will get automatically created, accessible on the settings page. Token needs to be passed as an authorization header with every request. Additionally session based authentication is enabled too: When you are logged in to your TubeArchivist instance, you'll have access to the api in the browser for testing.
+
+Curl example:
+```shell
+curl -v /api/video/<video-id>/ \
+    -H "Authorization: Token xxxxxxxxxx"
+```
+
+Python requests example:
+```python
+import requests
+
+url = "/api/video/<video-id>/"
+headers = {"Authorization": "Token xxxxxxxxxx"}
+response = requests.get(url, headers=headers)
+```
