-Please visit the [Wiki](https://github.com/krille-chan/fluffychat/wiki) for build instructions:
+1. To build FluffyChat you need [Flutter](https://flutter.dev) and [Rust](https://www.rust-lang.org/tools/install)
 
-- https://github.com/krille-chan/fluffychat/wiki/How-To-Build
+2. Clone the repo:
+```
+git clone https://github.com/krille-chan/fluffychat.git
+cd fluffychat
+```
+3. Choose your target platform below and enable support for it.
+3.1 If you want, enable Googles Firebase Cloud Messaging:
+
+`git apply ./scripts/enable-android-google-services.patch`
+
+4. Debug with: `flutter run`
+
+### Android
+
+* Build with: `flutter build apk`
+
+### iOS / iPadOS
+
+* Have a Mac with Xcode installed, and set up for Xcode-managed app signing
+* If you want automatic app installation to connected devices, make sure you have Apple Configurator installed, with the Automation Tools (`cfgutil`) enabled
+* Set a few environment variables
+    * FLUFFYCHAT_NEW_TEAM: the Apple Developer team that your certificates should live under
+    * FLUFFYCHAT_NEW_GROUP: the group you want App IDs and such to live under (ie: com.example.fluffychat)
+    * FLUFFYCHAT_INSTALL_IPA: set to `1` if you want the IPA to be deployed to connected devices after building, otherwise unset

+
+### Web
+
+* Build with:
+```bash
+./scripts/prepare-web.sh # To install Vodozemac
+flutter build web --release

+
+* Optionally configure by serving a `config.json` at the same path as fluffychat.
+  An example can be found at `config.sample.json`. All values there are optional.
+  **Please only the values, you really need**. If you e.g. only want
