 # Container Action Template
 
-To get started, click the `Use this template` button on this repository [which will create a new repository based on this template](https://github.blog/2019-06-06-generate-new-repositories-with-repository-templates/).
+[![GitHub Super-Linter](https://github.com/actions/container-action/actions/workflows/linter.yml/badge.svg)](https://github.com/super-linter/super-linter)
+![CI](https://github.com/actions/container-action/actions/workflows/ci.yml/badge.svg)
 
-For info on how to build your first Container action, see the [toolkit docs folder](https://github.com/actions/toolkit/blob/master/docs/container-action.md).
+Use this template to bootstrap the creation of a container action. :rocket:
+
+This template includes compilation support, tests, a validation workflow,
+publishing, and versioning guidance.
+
+If you are new, there's also a simpler introduction in the
+[Hello World Docker Action](https://github.com/actions/hello-world-docker-action)
+repository.
+
+If you would like to use the
+[GitHub Actions Toolkit](https://github.com/actions/toolkit) in your container
+action, see the
+[Container Toolkit Action](https://github.com/actions/container-toolkit-action)
+repository.
+
+## Create Your Own Action
+
+To create your own action, you can use this repository as a template! Just
+follow the below instructions:
+
+1. Click the **Use this template** button at the top of the repository
+1. Select **Create a new repository**
+1. Select an owner and name for your new repository
+1. Click **Create repository**
+1. Clone your new repository
+
+## Initial Setup
+
+After you've cloned the repository to your local machine or codespace, you'll
+need to perform some initial setup steps before you can develop your action.
+
+> [!NOTE]
+>
+> You'll need to have a reasonably modern version of
+> [Docker](https://www.docker.com/get-started/) handy (e.g. docker engine
+> version 20 or later).
+
+1. :hammer_and_wrench: Build the container
+
+   Make sure to replace `actions/container-action` with an appropriate label for
+   your container.
+
+   ```bash
+   docker build -t actions/container-action .
+   ```
+
+1. :white_check_mark: Test the container
+
+   You can pass individual environment variables using the `--env` or `-e` flag.
+
+   ```bash
+   $ docker run --env INPUT_WHO_TO_GREET="Mona Lisa Octocat" actions/container-action
+   ::notice file=entrypoint.sh,line=7::Hello, Mona Lisa Octocat!
+   ```
+
+   Or you can pass a file with environment variables using `--env-file`.
+
+   ```bash
+   $ cat ./.env.test
+   INPUT_WHO_TO_GREET="Mona Lisa Octocat"
+
+   $ docker run --env-file ./.env.test actions/container-action
+   ::notice file=entrypoint.sh,line=7::Hello, Mona Lisa Octocat!
+   ```
+
+## Update the Action Metadata
+
+The [`action.yml`](action.yml) file defines metadata about your action, such as
+input(s) and output(s). For details about this file, see
+[Metadata syntax for GitHub Actions](https://docs.github.com/en/actions/creating-actions/metadata-syntax-for-github-actions).
+
+When you copy this repository, update `action.yml` with the name, description,
+inputs, and outputs for your action.
+
+## Update the Action Code
+
+In this template, the container action runs a shell script,
+[`entrypoint.sh`](./entrypoint.sh), when the container is launched. Since you
+can choose any base Docker image and language you like, you can change this to
+suite your needs. There are a few main things to remember when writing code for
+container actions:
+
+- Inputs are accessed using argument identifiers or environment variables
+  (depending on what you set in your `action.yml`). For example, the first input
+  to this action, `who-to-greet`, can be accessed in the entrypoint script using
+  the `$INPUT_WHO_TO_GREET` environment variable.
+
+  ```bash
+  GREETING="Hello, $INPUT_WHO_TO_GREET!"
+  ```
+
+- GitHub Actions supports a number of different workflow commands such as
+  creating outputs, setting environment variables, and more. These are
+  accomplished by writing to different `GITHUB_*` environment variables. For
+  more information, see
+  [Workflow commands](https://docs.github.com/en/actions/using-workflows/workflow-commands-for-github-actions).
+
+  | Scenario              | Example                                         |
+  | --------------------- | ----------------------------------------------- |
+  | Set environment vars  | `echo "MY_VAR=my-value" >> "$GITHUB_ENV"`       |
+  | Set outputs           | `echo "greeting=$GREETING" >> "$GITHUB_OUTPUT"` |
+  | Prepend to `PATH`     | `echo "$HOME/.local/bin" >> "$GITHUB_PATH"`     |
+  | Set `pre`/`post` vars | `echo "MY_VAR=my-value" >> "$GITHUB_STATE"`     |
+  | Set step summary      | `echo "{markdown}" >> "$GITHUB_STEP_SUMMARY"`   |
+
+  You can write multiline strings using the following syntax:
+
+  ```bash
+  {
+    echo "JSON_RESPONSE<<EOF"
+    curl https://example.com
+    echo "EOF"
+  } >> "$GITHUB_ENV"
+  ```
+
+- Make sure that the script being run is executable!
+
+  ```bash
+  git add entrypoint.sh
+  git update-index --chmod=+x entrypoint.sh
+  ```
+
+So, what are you waiting for? Go ahead and start customizing your action!
+
+1. Create a new branch
+
+   ```bash
+   git checkout -b releases/v1
+   ```
+
+1. Replace the contents of `entrypoint.sh` with your action code
+1. Build and test the container
+
+   ```bash
+   docker build -t actions/container-action .
+   docker run actions/container-action "Mona Lisa Octocat"
+   ```
+
+1. Commit your changes
+
+   ```bash
+   git add .
+   git commit -m "My first action is ready!"
+   ```
+
+1. Push them to your repository
+
+   ```bash
+   git push -u origin releases/v1
+   ```
+
+1. Create a pull request and get feedback on your action
+1. Merge the pull request into the `main` branch
+
+Your action is now published! :rocket:
+
+For information about versioning your action, see
+[Versioning](https://github.com/actions/toolkit/blob/master/docs/action-versioning.md)
+in the GitHub Actions toolkit.
+
+## Validate the Action
+
+You can now validate the action by referencing it in a workflow file. For
+example, [`ci.yml`](./.github/workflows/ci.yml) demonstrates how to reference an
+action in the same repository.
+
+```yaml
+steps:
+  - name: Checkout
+    id: checkout
+    uses: actions/checkout@v3
+
+  - name: Test Local Action
+    id: test-action
+    uses: ./
+    with:
+      who-to-greet: Mona Lisa Octocat
+
+  - name: Print Output
+    id: output
+    run: echo "${{ steps.test-action.outputs.greeting }}"
+```
+
+For example workflow runs, check out the
+[Actions tab](https://github.com/actions/container-action/actions)! :rocket:
+
+## Usage
+
+After testing, you can create version tag(s) that developers can use to
+reference different stable versions of your action. For more information, see
+[Versioning](https://github.com/actions/toolkit/blob/master/docs/action-versioning.md)
+in the GitHub Actions toolkit.
+
+To include the action in a workflow in another repository, you can use the
+`uses` syntax with the `@` symbol to reference a specific branch, tag, or commit
+hash.
+
+```yaml
+steps:
+  - name: Checkout
+    id: checkout
+    uses: actions/checkout@v3
+
+  - name: Test Local Action
+    id: test-action
+    uses: actions/container-action@v1 # Commit with the `v1` tag
+    with:
+      who-to-greet: Mona Lisa Octocat
+
+  - name: Print Output
+    id: output
+    run: echo "${{ steps.test-action.outputs.greeting }}"
+```
