+### How to build without `google-services.json`
+Ideally you need a Firebase project and `google-services.json` in `app` folder. This way you will be able to use all build variants. 
+
+If you don't need all build variants, you can:
+1. **Import** this project into Android Studio.
+2. **Select** any build variant that has *fdroid* in it's name (e.g. *fdroidDebug*).
+3. **Build**. You should see the following in **Build Output**:
+   ```
+   ...
+   > Configure project :app
+   Didn't add Google Services since F-Droid flavor was chosen.
+   ...
+   ```
+   There should some warnings from Firebase, ignore them.
+
+Open issue in case you need any sort of help. It's free.
