+# Automated Branch Pull Requests
+
+This action will open a pull request to master branch (or otherwise specified)
+whenever a branch with some prefix is pushed to. The idea is that you can
+set up some workflow that pushes content to branches of the repostory,
+and you would then want this push reviewed for merge to master.
+
+Here is an example of what to put in your `.github/main.workflow` file to
+trigger the action.
+
+```
+workflow "Create Pull Request" {
+  on = "push"
+  resolves = "Create New Pull Request"
+}
+
+action "Create New Pull Request" {
+  uses = "vsoch/pull-request-action@master"
+  env = {
+    BRANCH_PREFIX = "update/"
+    PULL_REQUEST_BRANCH = "master"
+  }
+}
+```
+
+Environment variables include:
+
+  - **BRANCH_PREFIX**: the prefix to filter to. If the branch doesn't start with the prefix, it will be ignored
+  - **PULL_REQUEST_BRANCH**: the branch to issue the pull request to. Defaults to master.
+
+## Example use Case: Update Registry
+
+As an example, I created this action to be intended for an [organizational static registry](https://www.github.com/singularityhub/registry-org) for container builds. Specifically, you
+have modular repositories building container recipes, and then opening pull requests to the 
+registry to update it. 
+
+ - the container collection pull request should be generated from a separate GitHub repository, including the folder structure (manifests, tags, collection README) that are expected.
+ - pushing a branch that starts with update/<namespace> should open a pull request, if it doens't exist. If the branch is already open for PR, it updates it.
