+# Nix Starter Config (Minimal version)
 
 This is a simple nix flake for getting started with NixOS + home-manager.
 
+[**Looking for the full version?**](https://github.com/Misterio77/nix-config/tree/main)
+
 # What this provides
 
 - NixOS configuration on `nixos/configuration.nix`, accessible via
   `nixos-rebuild --flake .`
 - Home-manager configuration on `home-manager/home.nix`, accessible via
   `home-manager --flake .`
-- Basic boilerplate for adding custom packages (under `pkgs`) and overlays
-  (under `overlays`). Accessible on your system, home config, as well as `nix
-  build .#package-name`
-- Boilerplate for custom NixOS (`modules/nixos`) and home-manager
-  (`modules/home-manager`) modules

+To get everything up and running, you need flake-enabled nix and/or home-manager.
 
-First off, check your nix version using `nix --version`.
+For simplicity, this minimal version does not include a bootstrap shell.
 
-### Version < 2.4
+Check the [NixOS wiki](https://nixos.wiki/wiki/Flakes) for information on how to enable flakes.
-
-Bummer, your nix version does not support flakes. But fear not!
-
-You _don't_ need to mess around with channels to get up and running.
-
-Just run:
-```bash
-nix-shell
-```
-
-Wow, that was easy. Our `shell.nix` file will detect you can't evaluate (nor
-lock) the flake, and will grab `nix` and `home-manager` from the latest
-`nixos-unstable` versions, just for you.
-
-Once you're bootstrapped, remember to run `nix flake lock` and commit the
-newly-created `flake.lock` into your repository, this will make future
-bootstraps reproductible.
-
-### Version >= 2.4
-
-Congrats, your nix version supports flakes! It's just hidden behind a feature flag.
-
-You can bootstrap with: 
-```bash
-nix --experimental-features develop "nix-command flakes" .#default
-```
-
-The shell will also enable those experimental features, so no need to pass that
-argument while you're inside (or after installation, if you set the option that
-enables them globally).
-
-This should generate a `flake.lock`. Remember to commit it, as this will make
-future bootstraps reproductible.

 # What next?
 
-## User password and secrets
+## Full version
 
-You have basically two ways of setting up default passwords:
+Once you're confortable with this flake, take a look at the [full
-- By default, you'll be prompted for a root password when installing with
+version](https://github.com/Misterio77/nix-config/tree/main), it includes
-  `nixos-install`. After you reboot, be sure to add a password to your own
+boilerplate for overlays, custom packages, and more.
-  account and lock root using `sudo passwd -l root`.
-- Alternatively, you can specify `initialPassword` for your user. This will
-  give your account a default password, be sure to change it after rebooting!
-  If you do, you should pass `--no-root-passwd` to `nixos-install`, to skip
-  setting a password on the root account.
-
-If you don't want to set your password imperatively, you can also use
-`passwordFile` for safely and declaratively setting a password from a file
-outside the nix store.
-
-There's also [more advanced options for secret
-management](https://nixos.wiki/wiki/Comparison_of_secret_managing_schemes),
-including some that can include them (encrypted) into your config repo and/or
-nix store, be sure to check them out if you're interested.
-
-## Dotfile management with home-manager
-
-Besides just adding packages to your environment, home-manager can also manage
-your dotfiles. I strongly recommend you do, it's awesome!
-
-For full nix goodness, check out the home-manager options with `man
-home-configuration.nix`. Using them, you'll be able to fully configure any
-program with nix syntax and its powerful abstractions.
-
-Alternatively, if you're still not ready to rewrite all your configs to nix
-syntax, there's home-manager options (such as `xdg.configFile`) for including
-files from your config repository into your usual dot directories. Add your
-existing dotfiles to this repo and try it out!
-
-## Try opt-in persistance
-
-You might have noticed that there's impurity in your NixOS system, in the form
-of configuration files and other cruft your system generates when running. What
-if you change them in a whim to get something working and forget about it?
-Boom, your system is not fully reproductible anymore.
-
-You can instead fully delete your `/` and `/home` on every boot! Nix is okay
-with a empty root on boot (all you need is `/boot` and `/nix`), and will
-happily reapply your configurations.
-
-There's two main approaches to this: mount a `tmpfs` (RAM disk) to `/`, or
-(using a filesystem such as btrfs or zfs) mount a blank snapshot and reset it
-on boot.
-
-For stuff that can't be managed through nix (such as games downloaded from
-steam, or logs), use [impermanence](https://github.com/nix-community/impermanence)
-for mounting stuff you to keep to a separate partition/volume (such as
-`/nix/persist` or `/persist`). This makes everything vanish by default, and you
-can keep track of what you specifically asked to be kept.
-
-Here's some awesome blog posts about it:
-- [Erase your darlings](https://grahamc.com/blog/erase-your-darlings)
-- [Encrypted BTRFS with Opt-In State on
-  NixOS](https://mt-caret.github.io/blog/posts/2020-06-29-optin-state.html)
-- [NixOS: tmpfs as root](https://elis.nu/blog/2020/05/nixos-tmpfs-as-root/) and
-  [tmpfs as home](https://elis.nu/blog/2020/06/nixos-tmpfs-as-home/)
-
-## Adding custom packages
-
-Something you want to use that's not in nixpkgs yet? You can easily build and
-iterate on a derivation (package) from this very repository.
-
-Create a folder with the desired name inside `pkgs`, and add a `default.nix`
-file containing a derivation. Be sure to also `callPackage` them on
-`pkgs/default.nix`.
-
-You'll be able to refer to that package from anywhere on your
-home-manager/nixos configurations, build them with `nix build .#package-name`,
-or bring them into your shell with `nix shell .#package-name`.
-
-See [the manual](https://nixos.org/manual/nixpkgs/stable/) for some tips on how
-to package stuff.
-
-## Adding overlays
-
-Found some outdated package on nixpkgs you need the latest version of? Perhaps
-you want to apply a patch to fix a behaviour you don't like? Nix makes it easy
-and manageble with overlays!
-
-Use the `overlay/default.nix` file for this.
-
-If you're creating patches, you can keep them on the `overlay` folder as well.
-
-See [the wiki article](https://nixos.wiki/wiki/Overlays) to see how it all
-works.
-
-## Adding your own modules
-
-Got some configurations you want to create an abstraction of? Modules are the
-answer. These awesome files can expose _options_ and implement _configurations_
-based on how the options are set.
-
-Create a file for them on either `modules/nixos` or `modules/home-manager`. Be
-sure to also add them to the listing at `modules/nixos/default.nix` or
-`modules/home-manager/default.nix`.
-
-See [the wiki article](https://nixos.wiki/wiki/Module) to learn more about
-them.
-
-## Adding more hosts or users
-
-You can organize them by hostname and username on `nixos` and `home-manager`
-directories, be sure to also add them to `flake.nix`.
-
-NixOS makes it easy to share common configuration between hosts (you might want
-to create a common directory for these), while keeping everything in sync.
-home-manager can help you sync your environment (from editor to WM and
-everything in between) anywhere you use it. Have fun!
