 ### Compiling from source
 
-[For the time being, see the official Godot docs](https://docs.godotengine.org/en/latest/contributing/development/compiling)
-for compilation instructions for every supported platform.
+#### Using Nix (recommended)
+
+If you have the Nix package manager installed, you can build and run the editor in one command:
+
+```bash
+nix run .
+```
+
+This will automatically install all build dependencies and compile Redot if the binary doesn't exist.
+
+For manual control over the build process:
+
+```bash
+# Enter the Nix development environment
+nix develop
+
+# Build Redot (use 'macos' on macOS, 'linuxbsd' on Linux)
+scons platform=linuxbsd  # or: scons platform=macos
+
+# Run the editor - binary name reflects your platform and architecture
+# Examples: redot.linuxbsd.editor.x86_64, redot.macos.editor.arm64
+./bin/redot.<platform>.editor.<arch>
+```
+
+Nix works on Linux and macOS, and is available at [nixos.org/download.html](https://nixos.org/download.html). The `nix run .` command automatically detects your platform and architecture.
