+Note: In *public* repositories this action does not work in `pull_request` workflows when triggered by forks.
+Any attempt will be met with the error, `Resource not accessible by integration`.
+This is due to token restrictions put in place by GitHub Actions. Private repositories can be configured to [enable workflows](https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/enabling-features-for-your-repository/managing-github-actions-settings-for-a-repository#enabling-workflows-for-forks-of-private-repositories) from forks to run without restriction. See [here](https://github.com/peter-evans/create-pull-request/blob/main/docs/concepts-guidelines.md#restrictions-on-repository-forks) for further explanation. Alternatively, use the [`pull_request_target`](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#pull_request_target) event to comment on pull request commits.
 
-## Example
+#### Outputs
 
-Here is an example setting optional input parameters.
+The ID of the created comment will be output for use in later steps.
+Note that in order to read the step output the action step must have an id.
 
 ```yml
       - name: Create commit comment
-        uses: peter-evans/commit-comment@v2
+        uses: peter-evans/commit-comment@v3
+        id: cc
         with:
-          sha: 843dea1cc2e721163c20a5c876b5b155f7f3aa75

+        run: |
+          echo "Comment ID - ${{ steps.cc.outputs.comment-id }}"
 ```
 
 ### Setting the comment body from a file
 
-This example shows how file content can be read into a variable and passed to the action.
+```yml
+      - name: Create commit comment
+        uses: peter-evans/commit-comment@v3
+        with:
+          body-path: 'comment-body.md'
+```
+
+### Using a markdown template
 
+In this example, a markdown template file is added to the repository at `.github/comment-template.md` with the following content.
+```
+This is a test comment template
+Render template variables such as {{ .foo }} and {{ .bar }}.
+```
+
+The template is rendered using the [render-template](https://github.com/chuhlomin/render-template) action and the result is used to create the comment.
 ```yml
-      - id: get-comment-body
-        run: |
-          body="$(cat comment-body.txt)"
-          delimiter="$(openssl rand -hex 8)"
-          echo "body<<$delimiter" >> $GITHUB_OUTPUT
-          echo "$body" >> $GITHUB_OUTPUT
-          echo "$delimiter" >> $GITHUB_OUTPUT
+      - name: Render template
+        id: template
+        uses: chuhlomin/render-template@v1.4
+        with:
+          template: .github/comment-template.md
