+Auto-fill is context-sensitive. This means that the bitwarden auto-fill icon, and notification will only appear when it detects a login form or when the password field is selected.
+
+## Testing auto-fill
+1. Open an app that has not been signed in to
+2. Tap the password box
+    - The bitwarden icon will appear in the notification bar
+3. Open the notification drawer and tap **bitwarden Auto-fill Service**
+    - Your vault will display all matching logins otherwise you may need to manually search for it
+4. Tap the appropriate login
+    - Your username and password will be auto-filled
+
+## Troubleshooting
+**The bitwarden Auto-fill Service keeps getting disabled**
+
+Android may turn off the bitwarden Auto-fill Service to optimize battery life. To resolve this you can either:
+- Tell Android to ignore battery optimization for the bitwarden; or
+- Manually turn on the bitwarden Auto-fill Service each time
