+# Guess Game
+The game generates a secret number from 0 to 255. The player's task is to name a secret number.
+
+## Requirements
+- Rust
+- Cargo
+
+I recommend using [rustup](https://rustup.rs/) to install Rust.
+- Install rustup on Arch Linux: `sudo pacman -S rustup --needed`
+
+## Building
+`cargo b` (debug build)
+
+The executable files will be located in target/debug.
+
+`cargo b --release` (release build, what you need 😀)
+
+The executable files will be located in target/release.
