+## Installation
+For compiling m32chat, you only need a recent Rust toolchain. [rustup.rs](https://rustup.rs/) could help you with it.
+
+- After getting the source code, you can compile it with `cargo build --release`.
+- Copy the binary for example to `/usr/local/bin/`.
+- You can use the systemd template for m32chat and adapt it to your needs (i.e. customize the user name under which the service should run).
+
+Setting the environment variable `RUST_LOG=Debug` will give you some debug messages.
