+## Using Nix Flakes
+
+You can use [Nix flakes](https://nixos.wiki/wiki/Flakes) to run or build `rmxt` without installing Rust or any dependencies manually. This is the recommended method for Nix users.
+
+**Prerequisites:**
+- [Nix package manager](https://nixos.org/download.html) (version 2.4+)
+- Flakes enabled (see [NixOS Wiki: Flakes](https://nixos.wiki/wiki/Flakes#Installing_flakes))
+
+### Run `rmxt` directly (no install)
+
+```bash
+nix run github:santoshxshrestha/rmxt
+```
+
+Or, if you have cloned the repo:
+
+```bash
+nix run .
+```
+
+This will build and run the latest `rmxt` binary in a temporary environment.
+
+### Build the binary
+
+```bash
+nix build github:santoshxshrestha/rmxt
+```
+
+Or, from a local clone:
+
+```bash
+nix build
+```
+
+The compiled binary will be available at `./result/bin/rmxt`.
+
+### Development shell
+
+For contributors, you can enter a shell with all development dependencies:
+
+```bash
+nix develop
+```
+
+### Notes
+- The provided flake currently supports `x86_64-linux`.
+- For more details on Nix flakes, see the [NixOS Wiki](https://nixos.wiki/wiki/Flakes) or [Practical Nix Flakes](https://serokell.io/blog/practical-nix-flakes).
