+it. We enforce some of these, but not all, via `./gradlew 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
 
-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.
+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.
 
-### Running tests in Android Studio
+For a quick way to run a specific JUnit/Robolectric test:
 
-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_.
+    ./gradlew testFullDebugUnitTest --tests *LocaleSelectionTest*
 
-## Versioning
+For a quick way to run a specific emulator test:
 
-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.
+	./gradlew connectedFullDebugAndroidTest \
+        -Pandroid.testInstrumentationRunnerArguments.class=org.fdroid.fdroid.MainActivityExpressoTest
 
-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.
 
-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).
+## Making releases
 
-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.
