+it. We enforce some of these, but not all, via checkstyle.

+## Debugging
+
+To get all the logcat messages by F-Droid, you can run:
+
+    adb logcat | grep `adb shell ps | grep org.fdroid.fdroid | cut -c10-15`
+
+## Building tips
+
+* Use gradle with `--daemon` if you are going to build F-Droid multiple times.
+* If you get a message like `Could not find com.android.support:support-...`,
+  make sure that you have the latest Android support maven repository.
+* When building as part of AOSP with `Android.mk`, make sure you have a
+  recent version of Gradle installed as `gradlew` will not be used.

 ## Running the test suite

-Before pushing commits to a merge request, make sure this passes:
-
-    ./gradlew checkstyle pmd lint
-
 In order to run the F-Droid test suite, you will need to have either a real device
 connected via `adb`, or an emulator running. Then, execute the following from the
 command line:

    ./gradlew check

-Many important tests require a device or emulator, but do not work in GitLab CI.
-That mean they need to be run locally, and that is usually easiest in Android
-Studio rather than the command line.
+Note that the CI already runs the tests on an emulator, so you don't
+necessarily have to do this yourself if you open a merge request as the tests
+will get run.

-For a quick way to run a specific JUnit/Robolectric test:
+### Running tests in Android Studio

-    ./gradlew testFullDebugUnitTest --tests *LocaleSelectionTest*
+Later versions of Android Studio require tests to be run with a "Working directory"
+of `$MODULE_DIR$`.
+[To make this the default behaviour](https://code.google.com/p/android/issues/detail?id=158015#c11),
+close any projects to get the Welcome dialog. Then choose _Configure > Project Defaults >
+Run Configurations > Defaults > Android JUnit_, and change "Working directory"
+to `$MODULE_DIR$`. If you already have a project setup in Android Studio, you
+may also need to change the default in _Run > Edit Configurations... > Defaults >
+Android JUnit_.

-For a quick way to run a specific emulator test:
+## Versioning

-	./gradlew connectedFullDebugAndroidTest \
-        -Pandroid.testInstrumentationRunnerArguments.class=org.fdroid.fdroid.MainActivityExpressoTest
+Each stable version follows the `X.Y` pattern. Hotfix releases - i.e. when a
+stable has an important bug that needs immediate fixing - will follow the
+`X.Y.Z` pattern.

+Before each stable release, a number of alpha releases will be released. They
+will follow the pattern `X.Y-alphaN`, where `N` is the current alpha number.
+These will usually include changes and new features that have not been tested
+enough for a stable release, so use at your own risk. Testers and reporters
+are very welcome.

-## Making releases
+The version codes use a number of digits per each of these keys: `XXXYYYZNN`.
+So for example, 1.3.1 would be `1003150` and 0.95-alpha13 would be `95013`
+(leading zeros are omitted).

-See https://gitlab.com/fdroid/wiki/-/wikis/Internal/Release-Process#fdroidclient
+Note that we use a trailing `50` for actual stable releases, so alphas are
+limited to `-alpha49`.
+
+This is an example of a release process for **0.95**:
+
+* We are currently at stable **0.94**
+* **0.95-alpha1** is released
+* **0.95-alpha2** is released
+* **0.95-alpha3** is released
+* `stable-v0.95` is branched and frozen
+* **0.95** is released
+* A bug is reported on the stable release and fixed
+* **0.95.1** is released with only that fix
+
+As soon as a stable is tagged, master will move on to `-alpha0` on the next
+version. This is a temporary measure - until `-alpha1` is released - so that
+moving from stable to master doesn't require a downgrade. `-alpha0` versions
+will not be tagged nor released.
