+### `pre-commit` tool
+
+If you have Nix files in a Git repo and you want to make sure that they’re formatted with `nixfmt`, then you can use the `pre-commit` tool from [pre-commit.com](https://pre-commit.com):
+
+1. Make sure that you have the `pre-commit` command:
+
+    ```console
+    $ pre-commit --version
+    pre-commit 3.7.1
+    ```
+
+2. Make sure that you’re in your Git repo:
+
+    ```console
+    $ cd <path-to-git-repo>
+    ```
+
+3. Make sure that the `pre-commit` tool is installed as a Git pre-commit hook:
+
+    ```console
+    $ pre-commit install
+    pre-commit installed at .git/hooks/pre-commit
+    ```
+
+4. If you don’t already have one, then create a `.pre-commit-config.yaml` file.
+
+5. Add an entry for the `nixfmt` hook to your `.pre-commit-config.yaml` file:
+
+    ```yaml
+    repos:
+        - repo: https://github.com/NixOS/nixfmt
+          rev: <version>
+          hooks:
+                - id: nixfmt
+    ```
+
+    If you want to use a stable version of `nixfmt`, then replace `<version>` with a tag from this repo. If you want to use an unstable version of `nixfmt`, then replace `<version>` with a commit hash from this repo.
+
+6. Try to commit a badly formatted Nix file in order to make sure that everything works.
+
+> [!WARNING]
+> `nixfmt`’s integration with the `pre-commit` tool is relatively new. At the moment, none of the stable releases of `nixfmt` can be used with the `pre-commit` tool. You’ll have to use an unstable version for the time being.
