+## 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.

- * It will first list all listening TCP sockets, and next list all established
- * TCP connections. A typical entry of /proc/net/tcp would look like this (split
- * up into 3 parts because of the length of the line):

- * |----------------------------------> number of entry
- * <p>
- * 00000150:00000000 01:00000019 00000000
- * | | | | |--> number of unrecovered RTO timeouts
- * | | | |----------> number of jiffies until timer expires
- * | | |----------------> timer_active (see below)
- * | |----------------------> receive-queue

- * | | | | | | | |-------> (ack.quick<<1)|ack.pingpong
- * | | | | | | |---------> Predicted tick of soft clock
- * | | | | | | (delayed ACK control data)

-/**
- * An {@link IntentService} subclass for scanning removable "external storage"
- * for F-Droid package repos, e.g. SD Cards. This is intended to support
- * sharable package repos, so it ignores non-removable storage, like the fake
- * emulated sdcard from devices with only built-in storage.  This method will
- * only ever allow for reading repos, never writing.  It also will not work
- * for removeable storage devices plugged in via USB, since do not show up as
- * "External Storage"
- * <p>
- * Scanning the removable storage requires that the user allowed it.  This
- * requires both the {@link org.fdroid.fdroid.Preferences#isScanRemovableStorageEnabled()}
- * and the {@link android.Manifest.permission#READ_EXTERNAL_STORAGE}
- * permission to be enabled.
- *
- * @see TreeUriScannerIntentService TreeUri method for writing repos to be shared

-/**
- * A splash screen encouraging people to start the swap process. The swap
- * process is quite heavy duty in that it fires up Bluetooth and/or WiFi
- * in  order to scan for peers. As such, it is quite convenient to have a
- * more lightweight view to show in the main navigation that doesn't
- * automatically start doing things when the user touches the navigation
- * menu in the bottom navigation.
- * <p>
- * Lots of pieces of the nearby/swap functionality require that the user grant
- * F-Droid permissions at runtime on {@code android-23} and higher. On devices
- * that have a removable SD Card that is currently mounted, this will request
- * permission to read it, so that F-Droid can look for repos on the SD Card.
- * <p>
- * Once {@link Manifest.permission#READ_EXTERNAL_STORAGE} or
- * {@link Manifest.permission#WRITE_EXTERNAL_STORAGE} is granted for F-Droid,
- * then it can read any file on an SD Card and no more prompts are needed. For
- * USB OTG drives, the only way to get read permissions is to prompt the user
- * via {@link Intent#ACTION_OPEN_DOCUMENT_TREE}.
- * <p>
- * For write permissions, {@code android-19} and {@code android-20} devices are
- * basically screwed here.  {@link Intent#ACTION_OPEN_DOCUMENT_TREE} was added
- * in {@code android-21}, and there does not seem to be any other way to get
- * write access to the the removable storage.
- *
- * @see TreeUriScannerIntentService
