+Contributing to DAVx⁵
+=====================
+
 **Thank you for your interest in contributing to DAVx⁵!**
 
+Because you're reading this, you're probably interested in
+contributing to the DAVx⁵ code. [Other ways to contribute:
+see here.](https://www.davx5.com/donate#c306)
 
-# Licensing
+To contribute:
 
-All work in this repository is [licensed under the GPLv3](LICENSE).
-
-We (bitfire.at, initial and main contributors) are also asking you to give us
-permission to use your contribution for related non-open source projects
-like [Managed DAVx⁵](https://www.davx5.com/organizations/managed-davx5).
-
-If you send us a pull request, our CLA bot will ask you to sign the
-Contributor's License Agreement so that we can use your contribution.
+1. It's good idea to have a look at the [DAVx⁵ Roadmap](https://gitlab.com/bitfireAT/davx5-ose/wikis/Roadmap)
+   to see whether the change is already planned. Maybe there's even a link to a
+   corresponding forum thread there.
+1. Determine which project the changes shall go to. There's
+   the DAVx⁵ main project (this repo), and the [related
+   libraries](README.md).
+1. Please post to the [DAVx⁵ development forum](https://www.davx5.com/forums)
+   before doing actual work (unless you do it only for yourself, of course).
+   This will help to coordinate activities and you'll also get hints
+   about where to start and possible pitfalls.
+1. Fork the repository.
+1. Do the changes in your repository.
+1. Submit a pull request to the original project.
+1. Post in the forum again (to make sure the pull request is being notified).
 
 
-# Copyright
+Questions, discussion
+=====================
 
-Make sure that every file that contains significant work (at least every code file)
-starts with the copyright header:
-
-```
-/*
- * Copyright © All Contributors. See LICENSE and AUTHORS in the root directory for details.
- */
-```
-
-You can set this in Android Studio:
-
-1. Settings / Editor / Copyright / Copyright Profiles
-2. Paste the text above (without the stars).
-3. Set Formatting so that the preview exactly looks like above; one blank line after the block.
-4. Set this copyright profile as the default profile for the project.
-5. Apply copyright: right-click in file tree / Update copyright.
+We're happy to see questions, discussions etc. in the
+[DAVx⁵ development forum](https://www.davx5.com/forums)!
 
 
-# Style guide
+Licensing
+=========
 
-Please adhere to the [Kotlin style guide](https://developer.android.com/kotlin/style-guide) and
-the following hints to make the source code uniform.
+All code has to be licensed under the GPL.
 
-**Have a look at similar files and copy their style if you're not certain.**
+We (bitfire.at, initial developers) are also asking you to double-license the
+code so that we can also use it for related non-open source projects like
+[Managed DAVx⁵](https://www.davx5.com/organizations/managed-davx5).
 
-Sample file (pay attention to blank lines and other formatting):
-
-```
-<Copyright header, see above>
-
-class MyClass(int arg1) : SuperClass() {
-
-    companion object {
-
-        const val CONSTANT_STRING = "Constant String";
-
-        fun staticMethod() {	// Use static methods when you don't need the object context.
-            // …
-        }
-
-    }
-
-    var someProperty: String = "12345"
-    var someRelatedProperty: Int = 12345
-
-    init {
-        // constructor
-    }
-
-
-    /**
-     * Use KDoc to document important methods. Don't use it dogmatically, but writing proper documentation
-     * (not just the method name with spaces) helps you to re-think what the method shall really do.
-     */
-    fun aFun1() {		// Group methods by some logic (for instance, the order in which they will be called)
-    }				// and alphabetically within a group.
-
-    fun anotherFun() {
-        // …
-    }
-
-
-    fun somethingCompletelyDifferent() {	// two blank lines to separate groups
-    }
-
-    fun helperForSomethingCompletelyDifferent() {
-        someCall(arg1, arg2, arg3, arg4)	// function calls: stick to one line unless it becomes confusing
-    }
-
-
-    class Model(				// two blank lines before inner classes
-        someArgument: SomeLongClass,		// arguments in multiple lines when they're too long for one line
-        anotherArgument: AnotherLongType,
-        thirdArgument: AnotherLongTypeName
-    ) : ViewModel() {
-
-        fun abc() {
-        }
-
-    }
-
-}
-```
-
-In general, use one blank line to separate things within one group of things, and two blank lines
-to separate groups. In rare cases, when methods are tightly coupled and are only helpers for another
-method, they may follow the calling method without separating blank lines.
-
-## Tests
-
-Test classes should be in the appropriate directory (see existing tests) and in the same package as the

-/**
- * JUnit ClassRule which initializes the AOSP CalendarProvider.
- *
- * It seems that the calendar provider unfortunately forgets the very first requests when it is used the very first time,
- * maybe by some wrongly synchronized database initialization. So things like querying the instances
- * fails in this case.
- *
- * So this rule is needed to allow tests which need the calendar provider to succeed even when the calendar provider
- * is used the very first time (especially in CI tests / a fresh emulator).
- *
- * See [at.bitfire.davdroid.resource.LocalCalendarTest] for an example of how to use this rule.
