 - The [Nix installer from Determinate Systems](https://github.com/DeterminateSystems/nix-installer?tab=readme-ov-file#determinate-nix-installer) is only recommended for use with flake-based setups. **Make sure you use it without the `--determinate` flag**. The `--determinate` flag installs the Determinate Nix distribution which does not work out of the box with nix-darwin.
 * The [Lix installer](https://lix.systems/install/#on-any-other-linuxmacos-system) supports both flake-based and channel-based setups.
 
-## Installing
 
-If you wish to use nix-darwin with flakes, please refer to the [flakes](#flakes) section.
 
-```bash
+## Getting started
-nix-build https://github.com/LnL7/nix-darwin/archive/master.tar.gz -A installer
-./result/bin/darwin-installer
-```
 
-## Updating
+Despite being an experimental feature in Nix currently, nix-darwin recommends that beginners use flakes to manage their nix-darwin configurations.
 
-The installer will configure a channel for this repository.

-```bash
-nix-channel --update darwin
-darwin-rebuild changelog
-```
-
-> NOTE: If you are using Nix as a daemon service the channel for that will be owned by root.
-> Use `sudo -i nix-channel --update darwin` instead.
-
-## Uninstalling
-
-To run the latest version of the uninstaller, you can run the following command:
-
-```
-nix --extra-experimental-features "nix-command flakes" run nix-darwin#darwin-uninstaller
-```
-
-If that command doesn't work for you, you can try the locally installed uninstaller:
-
-```
-darwin-uninstaller
-```
-
-## Example configuration
-
-Configuration lives in `~/.nixpkgs/darwin-configuration.nix`. Check out
-[modules/examples](https://github.com/LnL7/nix-darwin/tree/master/modules/examples) for some example configurations.

-## Flakes

-nix-darwin aims for both non-flake and flake configurations to be well supported despite flakes being an experimental feature in Nix.
