+# Contributing to AlterWare Launcher
+
+We welcome contributions to the AlterWare Launcher! Here are some guidelines to follow:
+
+> [!NOTE]
+> Always run `cargo fmt` and `cargo clippy` to ensure your code is formatted correctly and passes lint checks.
+
+### Prerequisites
+
+- [Rust](https://rustup.rs/) - Install the latest stable version
+- [Git](https://git-scm.com/) - For cloning the repository
+- [Perl](https://www.perl.org/get.html) - [Linux only]  Required for OpenSSL
+
+### Build Steps
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/mxve/alterware-launcher.git
+   cd alterware-launcher
+   ```
+
+2. Build the project:
+   ```bash
+   cargo build --release
+   ```
+
+3. Find the executable:
+   The compiled binary will be located at `target/release/alterware-launcher(.exe)`
+
+### Additional Notes
+
+- Structs generally go in `src/structs.rs`
+- Try to follow the existing coding style, make use of `cargo fmt` and `cargo clippy` to ensure consistency
+- Use existing formatting, printing and helper functions when possible (see `src/misc.rs` and `src/extend.rs`)
+- Unit tests go in `src/tests.rs`
+- Make sure your code compiles on Windows and Unix targets
+  - The GitHub Actions currently only run on Linux
+    - You can use these to check for errors on unix platforms
+    - You have to verify your code on Windows manually
+- For debugging, you can use `cargo build` without the `--release` flag. The debug build will be slower but includes additional debugging information.
+- To run tests, use `cargo test`
