+# OpenShift-Ansible Git Hooks
+
+## Introduction
+
+This `hack` sub-directory holds
+[git commit hooks](https://www.atlassian.com/git/tutorials/git-hooks#conceptual-overview)
+you may use when working on openshift-ansible contributions. See the
+README in each sub-directory for an overview of what each hook does
+and if the hook has any specific usage or setup instructions.
+
+## Usage
+
+Basic git hook usage is simple:
+
+1) Copy (or symbolic link) the hook to the `$REPO_ROOT/.git/hooks/` directory
+2) Make the hook executable (`chmod +x $PATH_TO_HOOK`)
+
+## Multiple Hooks of the Same Type
+
+If you want to install multiple hooks of the same type, for example:
+multiple `pre-commit` hooks, you will need some kind of *hook
+dispatcher*. For an example of an easy to use hook dispatcher check
+out this gist by carlos-jenkins:
+
+* [multihooks.py](https://gist.github.com/carlos-jenkins/89da9dcf9e0d528ac978311938aade43)
+
+## Contributing Hooks
+
+If you want to contribute a new hook there are only a few criteria
+that must be met:
+
+* The hook **MUST** include a README describing the purpose of the hook
+* The README **MUST** describe special setup instructions if they are required
+* The hook **MUST** be in a sub-directory of this directory
+* The hook file **MUST** be named following the standard git hook
+  naming pattern (i.e., pre-commit hooks **MUST** be called
+  `pre-commit`)

+# Verify Generated Modules
+
+Pre-commit hook for verifying that generated library modules match
+their EXPECTED content. Library modules are generated from fragments
+under the `roles/lib_(openshift|utils)/src/` directories.
+
+If the attempted commit modified files under the
+`roles/lib_(openshift|utils)/` directories this script will run the
+`generate.py --verify` command.
+
+This script will **NOT RUN** if module source fragments are modified
+but *not part of the commit*. I.e., you can still make commits if you
+modified module fragments AND other files but are *not comitting the
+the module fragments*.
+
+# Setup Instructions
+
+Standard installation procedure. Copy the hook to the `.git/hooks/`
+directory and ensure it is executable.
