 ## Code contribution
 
-* If you want to help out with an existing bug report or feature request, leave a comment on that issue saying you want to try your hand at it.
-* If there is no existing issue for what you want to work on, open a new one describing your changes. This gives the team and the community a chance to give feedback before you spend time on something that is already in development, should be done differently, or should be avoided completely.
-* Stick to NewPipe's style conventions of [checkStyle](https://github.com/checkstyle/checkstyle). It runs each time you build the project.
-* Do not bring non-free software (e.g. binary blobs) into the project. Make sure you do not introduce Google
-  libraries.
+### Guidelines
+
+* Stick to NewPipe's *style conventions* of [checkStyle](https://github.com/checkstyle/checkstyle) and [ktlint](https://github.com/pinterest/ktlint). They run each time you build the project.
 * Stick to [F-Droid contribution guidelines](https://f-droid.org/wiki/page/Inclusion_Policy).
-* Make changes on a separate branch with a meaningful name, not on the _master_ branch or the _dev_ branch. This is commonly known as *feature branch workflow*. You may then send your changes as a pull request (PR) on GitHub.
-* Please test (compile and run) your code before submitting changes! Ideally, provide test feedback in the PR description. Untested code will **not** be merged!
-* Make sure your PR is up-to-date with the rest of the code. Often, a simple click on "Update branch" will do the job, but if not, you must rebase the dev branch manually and resolve the problems on your own. You can find help [on the wiki](https://github.com/TeamNewPipe/NewPipe/wiki/How-to-merge-a-PR). That makes the maintainers' jobs way easier.
-* Please show intention to maintain your features and code after you contribute a PR. Unmaintained code is a hassle for core developers. If you do not intend to maintain features you plan to contribute, please rethink your submission, or clearly state that in the PR description.
+* In particular **do not bring non-free software** (e.g. binary blobs) into the project. Make sure you do not introduce any closed-source library from Google.
+
+### Before starting development
+
+* If you want to help out with an existing bug report or feature request, **leave a comment** on that issue saying you want to try your hand at it.
+* If there is no existing issue for what you want to work on, **open a new one**  describing the changes you are planning to introduce. This gives the team and the community a chance to give **feedback** before you spend time on something that is already in development, should be done differently, or should be avoided completely.
+* Please show **intention to maintain your features** and code after you contribute a PR. Unmaintained code is a hassle for core developers. If you do not intend to maintain features you plan to contribute, please rethink your submission, or clearly state that in the PR description.
+* Create PRs that cover only **one specific issue/solution/bug**. Do not create PRs that are huge monoliths and could have been split into multiple independent contributions.
+* NewPipe uses [NewPipeExtractor](https://github.com/TeamNewPipe/NewPipeExtractor) to fetch data from services. If you need to change something there, you must test your changes in NewPipe. Telling NewPipe to use your extractor version can be accomplished by editing the `app/build.gradle` file: the comments under the "NewPipe libraries" section of `dependencies` will help you out.
+
+### Kotlin in NewPipe
+* NewPipe will remain mostly Java for time being
+* Contributions containing a simple conversion from Java to Kotlin should be avoided. Conversions to Kotlin should only be done if Kotlin actually brings improvements like bug fixes or better performance which are not, or only with much more effort, implementable in Java. The core team sees Java as an easier to learn and generally well adopted programming language.
+
+### Creating a Pull Request (PR)
+
+* Make changes on a **separate branch** with a meaningful name, not on the _master_ branch or the _dev_ branch. This is commonly known as *feature branch workflow*. You may then send your changes as a pull request (PR) on GitHub.
+* Please **test** (compile and run) your code before submitting changes! Ideally, provide test feedback in the PR description. Untested code will **not** be merged!
 * Respond if someone requests changes or otherwise raises issues about your PRs.
-* Send PRs that only cover one specific issue/solution/bug. Do not send PRs that are huge and consist of multiple independent solutions.
 * Try to figure out yourself why builds on our CI fail.
+* Make sure your PR is **up-to-date** with the rest of the code. Often, a simple click on "Update branch" will do the job, but if not, you must *rebase* your branch on the `dev` branch manually and resolve the conflicts on your own. You can find help [on the wiki](https://github.com/TeamNewPipe/NewPipe/wiki/How-to-merge-a-PR). Doing this makes the maintainers' job way easier.
+
+## IDE setup & building the app
+
+### Basic setup
+
+NewPipe is developed using [Android Studio](https://developer.android.com/studio/). Learn more about how to install it and how it works in the [official documentation](https://developer.android.com/studio/intro). In particular, make sure you have accepted Android Studio's SDK licences. Once Android Studio is ready, setting up the NewPipe project is fairly simple:
+- Clone the NewPipe repository with `git clone https://github.com/TeamNewPipe/NewPipe.git` (or use the link from your own fork, if you want to open a PR).
+- Open the folder you just cloned with Android Studio.
+- Build and run it just like you would do with any other app, with the green triangle in the top bar.
+
+You may find [SonarLint](https://www.sonarlint.org/intellij)'s **inspections** useful in helping you to write good code and prevent bugs.
+
+### checkStyle setup
+
+The [checkStyle](https://github.com/checkstyle/checkstyle) plugin verifies that Java code abides by the project style. It runs automatically each time you build the project. If you want to view errors directly in the editor, instead of having to skim through the build output, you can install an Android Studio plugin:
+- Go to `File -> Settings -> Plugins`, search for `checkstyle` and install `CheckStyle-IDEA`.
+- Go to `File -> Settings -> Tools -> Checkstyle`.
+- Add NewPipe's configuration file by clicking the `+` in the right toolbar of the "Configuration File" list.
+- Under the "Use a local Checkstyle file" bullet, click on `Browse` and pick the file named `checkstyle.xml` in the project's root folder.
+- Enable "Store relative to project location" so that moving the directory around does not create issues.
+- Insert a description in the top bar, then click `Next` and then `Finish`.
+- Activate the configuration file you just added by enabling the checkbox on the left.
+- Click `Ok` and you are done.
+
+### ktlint setup
+
+The [ktlint](https://github.com/pinterest/ktlint) plugin does the same job as checkStyle for Kotlin files. Installing the related plugin is as simple as going to `File -> Settings -> Plugins`, searching for `ktlint` and installing `Ktlint (unofficial)`.

  2. Download the APK from [Github Releases](https://github.com/TeamNewPipe/NewPipe/releases) and install it.
  3. Update via F-Droid. This is the slowest method of getting updates, as F-Droid must recognize changes, build the APK itself, sign it, then push the update to users.
  4. Build a debug APK yourself. This is the fastest way to get new features on your device, but is much more complicated, so we recommend using one of the other methods.
 
 We recommend method 1 for most users. APKs installed using method 1 or 2 are compatible with each other, but not with those installed using method 3. This is due to the same signing key (ours) being used for 1 and 2, but a different signing key (F-Droid's) being used for 3. Building a debug APK using method 4 excludes a key entirely. Signing keys help ensure that a user isn't tricked into installing a malicious update to an app.

 Recomendamos o método 2 para a maioria dos usuários. Os APKs instalados usando o método 2 ou 3 são compatíveis entre si, mas não com aqueles instalados usando o método 4.

+
+## Kurulum ve güncellemeler
+Aşağıdaki yöntemlerden birini kullanarak NewPipe'ı kurabilirsiniz:
+ 1. Özel depomuzu F-Droid'e ekleyin ve oradan yükleyin. Kılavuzu şurada bulabilirsiniz: https://newpipe.net/FAQ/tutorials/install-add-fdroid-repo/
+ 2. APK'yı [Github sürümlerinden](https://github.com/TeamNewPipe/NewPipe/releases) indirin ve kurun.
+ 3. F-Droid ile güncelleyin. Bu, güncellemeleri almanın en yavaş yöntemidir, çünkü F-Droid değişiklikleri tanımalı, APK'yı kendisi oluşturmalı, imzalamalı ve ardından güncellemeyi kullanıcılara dağıtmalıdır.
+ 4. Kendiniz bir APK derleyin. Bu yöntem, cihazınızda yeni özellikler edinmenin en hızlı yoludur, ancak çok daha karmaşıktır, bu nedenle diğer yöntemlerden birini kullanmanızı öneririz.
+
+Çoğu kullanıcı için yöntem 1'i öneririz. Yöntem 1 veya 2 kullanılarak yüklenen APK'lar birbiriyle uyumludur, ancak yöntem 3 kullanılarak yüklenenlerle uyumlu değildir. Bu durum, 1 ve 2 için kullanılan aynı imzalama anahtarıın (bizim anahtarımız) 3 için kullanılan imzalama anahtarından (F-Droid'in anahtarı) farklı olmasından kaynaklanmaktadır. Yöntem 4 kullanılarak oluşturulan deneysel APK'larda anahtar yoktur. İmzalama anahtarları, bir kullanıcının bir uygulamaya kötü amaçlı bir güncelleme yüklemek için kandırılmadığından emin olmanıza yardımcı olur.
+
+Bu arada, herhangi bir nedenle kaynakları değiştirmek istiyorsanız (örneğin, NewPipe'ın temel bir işlevi bozuldu ve F-Droid tarafında henüz bir güncelleme yayınlanmadı), bu prosedürü izlemenizi öneririz:
+1. Verilerinizi yedekleyin. `NewPipe Ayarları > İçerik > Veritabanını dışa aktar` seçeneklerini izleyerek aboneliklerinizi, oynatma listelerinizi ve geçmişinizi yedekleyin.
+2. NewPipe'ı kaldırın
+3. APK dosyasını yeni bir kaynaktan indirin ve yükleyin
+4. `Ayarlar > İçerik > Veritabanını içe aktar` seçeneklerini izleyerek 1. adımdaki verileri içe aktarın
