+# Development
+
+## Clone the repository
+
+```bash
+git clone https://gitlab.com/ahoneybun/nyxi-installer.git
+```
+
+## Enter the repository that you just cloned
+
+```bash
+cd nyxi-installer
+```
+
+## Enter nix-shell
+
+This is if you are already running NixOS on your system where development will take place. This will install the needed system packages, set environment variables and such for development.
+
+```bash
+nix-shell
+```
+
+## For distros like Ubuntu install these packages
+
+```bash
+sudo apt install build-essential pkg-config libcurl4-openssl-dev libfdisk-dev
+```
+
+## Building and testing
+
+You can use normal `cargo` commands like:
+
+- `cargo test`
+- `cargo build`
+- `cargo run`
+
+**NOTE:** you will need to build the program and run it with `sudo` currently so `cargo run` is not the best for testing.
