+# FreshRSS - Google Reader compatible API implementation
+
+See [Mobile access](../users/06_Mobile_access.md) for general aspects of API access.
+Additionally [page about our Fever compatible API](06_Fever_API.md) for another possibility.
+
+## RSS clients
+
+There are many RSS clients that support the Fever API, but they seem to understand the Fever API a bit differently.
+If your favourite client doesn't work properly with this API, please create an issue and we'll have a look.
+But we can **only** do that for free clients.
+
+### Usage & Authentication
+
+Before you can start using this API, you have to enable and setup API access, which is [documented here](../users/06_Mobile_access.md),
+and then reset the user’s API password.
+
+Then point your mobile application to the `greader.php` address (e.g. `https://freshrss.example.net/api/greader.php`).
+
+# Compatible clients
+
+6. On the same FreshRSS API page, note the address given under “Your API address”, like `https://freshrss.example.net/api/greader.php`
+	* Type the API address in a client, together with your FreshRSS username, and the corresponding special API password.
