-### Tag push events
+### Security
+
+From a security perspective it's good practice to fork third-party actions, review the code, and use your fork of the action in workflows.
+By using third-party actions directly the risk exists that it could be modified to do something malicious, such as capturing secrets.
+
+This action uses [ncc](https://github.com/zeit/ncc) to compile the Node.js code and dependencies into a single file.
+Python dependencies are vendored and committed to the repository [here](https://github.com/peter-evans/create-pull-request/tree/master/dist/vendor).
+No dependencies are downloaded during the action execution.
+
+Vendored Python dependencies can be reviewed by rebuilding the [dist](https://github.com/peter-evans/create-pull-request/tree/master/dist) directory and redownloading dependencies.
+The following commands require Node and Python 3.
+
+```
+npm install
+npm run clean
+npm run package
+```
+
+The `dist` directory should be rebuilt leaving no git diff.
+
+## Advanced usage
+
+### Creating pull requests in a remote repository
+
+Checking out a branch from a different repository from where the workflow is executing will make *that repository* the target for the created pull request. In this case, a `repo` scoped [Personal Access Token (PAT)](https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line) is required.
+
+```yml
+      - uses: actions/checkout@v2
+        with:
+          token: ${{ secrets.PAT }}
+          repository: owner/repo
+
+      # Make changes to pull request here
+
+      - uses: peter-evans/create-pull-request@v2
+        with:
+          token: ${{ secrets.PAT }}
+```
+
+### Push using SSH (deploy keys)
+
+[Deploy keys](https://developer.github.com/v3/guides/managing-deploy-keys/#deploy-keys) can be set per repository and so are arguably more secure than using a `repo` scoped [Personal Access Token (PAT)](https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line).
+Allowing the action to push with a configured deploy key will trigger `on: push` workflows. This makes it an alternative to using a PAT to trigger checks for pull requests.
+
+How to use SSH (deploy keys) with create-pull-request action:
+
+1. [Create a new SSH key pair](https://help.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent#generating-a-new-ssh-key) for your repository. Do not set a passphrase.
+2. Copy the contents of the public key (.pub file) to a new repository [deploy key](https://developer.github.com/v3/guides/managing-deploy-keys/#deploy-keys) and check the box to "Allow write access."
+3. Add a secret to the repository containing the entire contents of the private key.
+4. As shown in the example steps below, use the [`webfactory/ssh-agent`](https://github.com/webfactory/ssh-agent) action to install the private key and clone your repository. Remember to checkout the `base` of your pull request if it's not the default branch, e.g. `git checkout my-branch`.
+
+```yml
+    steps:
+      - uses: webfactory/ssh-agent@v0.2.0
+        with:
+          ssh-private-key: ${{ secrets.SSH_PRIVATE_KEY }}
+
+      - name: Checkout via SSH
+        run: git clone git@github.com:peter-evans/create-pull-request.git .
+
+      # Make changes to pull request here
+
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v2
+        with:
+          token: ${{ secrets.GITHUB_TOKEN }}
+```
+
+### Running in a container
+
+This action can be run inside a container by installing the action's dependencies either in the Docker image itself, or during the workflow.
+
+The action requires `python3`, `pip3` and `git` to be installed and on the `PATH`.
+
+Note that `actions/checkout` requires Git 2.18 or higher to be installed, otherwise it will just download the source of the repository instead of cloning it.
+
+**Alpine container example:**
+```yml
+jobs:
+  createPullRequestAlpine:
+    runs-on: ubuntu-latest
+    container:
+      image: alpine
+    steps:
+      - name: Install dependencies
+        run: apk --no-cache add git python3
+
+      - uses: actions/checkout@v2
+
+      # Make changes to pull request here
+
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v2
+        with:
+          token: ${{ secrets.GITHUB_TOKEN }}
+```
+
+**Ubuntu container example:**
+```yml
+jobs:
+  createPullRequestAlpine:
+    runs-on: ubuntu-latest
+    container:
+      image: ubuntu
+    steps:
+      - name: Install dependencies
+        run: |
+          apt-get update
+          apt-get install -y software-properties-common
+          add-apt-repository -y ppa:git-core/ppa
+          apt-get install -y python3 python3-pip git

+```
+
+### Creating pull requests on tag push
 
 An `on: push` workflow will also trigger when tags are pushed.
 During these events, the `actions/checkout` action will check out the `ref/tags/<tag>` git ref by default.

+### Keep a branch up-to-date with another
+
+This is a use case where a branch should be kept up to date with another by opening a pull request to update it. The pull request should then be updated with new changes until it is merged or closed.
+
+In this example scenario, a branch called `production` should be updated via pull request to keep it in sync with `master`. Merging the pull request is effectively promoting those changes to production.
+
+```yml
+name: Create production promotion pull request
+on:
+  push:
+    branches:
+      - master
+jobs:
+  productionPromotion:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v2
+        with:
+          ref: production
+      - name: Reset promotion branch
+        run: |
+          git fetch origin master:master
+          git reset --hard master
+      - name: Create Pull Request
+        uses: peter-evans/create-pull-request@v2
+        with:
+          token: ${{ secrets.GITHUB_TOKEN }}
+          branch: production-promotion
+```
+
 ## Use case: Create a pull request to update X periodically
 
 This pattern will work well for updating any kind of static content from an external source. The workflow executes on a schedule and raises a pull request when there are changes.
