+# Conduit for Nix/NixOS
+
+This guide assumes you have a recent version of Nix (^2.4) installed.
+
+Since Conduit ships as a Nix flake, you'll first need to [enable
+flakes][enable_flakes].
+
+You can now use the usual Nix commands to interact with Conduit's flake. For
+example, `nix run gitlab:famedly/conduit` will run Conduit (though you'll need
+to provide configuration and such manually as usual).
+
+If your NixOS configuration is defined as a flake, you can depend on this flake
+to provide a more up-to-date version than provided by `nixpkgs`. In your flake,
+add the following to your `inputs`:
+
+```nix
+conduit = {
+    url = "gitlab:famedly/conduit";
+
+    # Assuming you have an input for nixpkgs called `nixpkgs`. If you experience
+    # build failures while using this, try commenting/deleting this line. This
+    # will probably also require you to always build from source.
+    inputs.nixpkgs.follows = "nixpkgs";
+};
+```
+
+Next, make sure you're passing your flake inputs to the `specialArgs` argument
+of `nixpkgs.lib.nixosSystem` [as explained here][specialargs]. This guide will
+assume you've named the group `flake-inputs`.
+
+Now you can configure Conduit and a reverse proxy for it. Add the following to
+a new Nix file and include it in your configuration:
+
+```nix
+{ config
+, pkgs
+, flake-inputs
+, ...
+}:
+
+let
+  # You'll need to edit these values
+
+  # The hostname that will appear in your user and room IDs
+  server_name = "example.com";
+
+  # The hostname that Conduit actually runs on
+  #
+  # This can be the same as `server_name` if you want. This is only necessary
+  # when Conduit is running on a different machine than the one hosting your
+  # root domain. This configuration also assumes this is all running on a single
+  # machine, some tweaks will need to be made if this is not the case.
+  matrix_hostname = "matrix.${server_name}";
