+# cabal-gild action
+
+This `run-cabal-gild` GitHub Action helps to ensure that your Haskell project is
+formatted with [cabal-gild](https://github.com/tfausak/cabal-gild). The action
+tries to find all Cabal source code files in your repository and fails if any
+of them are not formatted. In case of failure it prints the diff between the
+actual contents of the file and its formatted version.
+
+## Example usage
+
+In the simple case all you need to do is to add this step to your job:
+
+```yaml
+- uses: input-output-hk/actions/run-cabal-gild@v1
+  with:
+    version: "1.7.0.1"
+```
+
+The `1.7.0.1` should be replaced with the version of cabal-gild you want to use.  See
+[cabal-gild releases](https://github.com/tfausak/cabal-gild/releases) for all cabal-gild versions.
+If you don't specify this cabal-gild `version` input, the latest version of
+cabal-gild will be used.
