+
+### Configuring a workflow
+
+Actions are enabled on your repository by default, but we still have to tell our repository to use them. We do this by creating a workflow file in our repository.
+
+A **workflow** file can be thought of as the recipe for automating a task. They house the start to finish instructions, in the form of `jobs` and `steps`, for what should happen based on specific triggers.
+
+Your repository can contain multiple **workflow** files that carry out a wide variety of tasks. It is important to consider this when deciding on a name for your **workflow**. The name you choose should reflect the tasks being performed.
+
+_In our case, we will use this one **workflow** file for many things, which leads us to break this convention for teaching purposes._
+
+Read more about [workflows](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/configuring-a-workflow#choosing-the-type-of-actions-for-your-workflow)
+
+## On to your development environment
+
+Our JavaScript actions are going to leverage the [GitHub ToolKit](https://github.com/actions/toolkit) for developing GitHub Actions.
+
+This is an external library that we will install using `npm` which means that you will need [Node.js](https://nodejs.org/) installed.
+
+We find writing actions to be easier from a local environment vs trying to do everything right here in the repository. Doing these steps locally allows you to use the editor of your choice so that you have all the extensions and snippets you are used to when writing code.
+
+If you do not have a preferred environment then we suggest following along exactly as you see on the screen, which means you'll need to install [Visual Studio Code](https://code.visualstudio.com/).
+
+## Don't forget to set up your workstation
+
+Most of your work going forward will take place away from your Skills repository, so before continuing with the course ensure you have the following installed on your **local machine**.
+
+1. [ ] [Node.js](https://nodejs.org)
+2. [ ] [Visual Studio Code](https://code.visualstudio.com/) or your editor of choice
+3. [ ] [Git](https://git-scm.com/)
+
+### :keyboard: Activity 1: Initialize a new JavaScript project
+
+Once you have the necessary tools installed locally, follow these steps to begin creating your first action.
+
+1. Open the **Terminal** (Mac and Linux) or **Command Prompt** (Windows) on your local machine
+2. Clone your Skills repo to your local machine:
+   ```shell
+   git clone <this repository URL>.git
+   ```
+3. Navigate to the folder you just cloned:
+   ```shell
+   cd <local folder with cloned repo>
+   ```
+4. We are using branch called `main`.
+   ```shell
+   git switch main
+   ```
+5. Create a new folder for our actions files:
+   ```shell
+   mkdir -p .github/actions/joke-action
+   ```
+6. Navigate to the `joke-action` folder you just created:
+   ```shell
+   cd .github/actions/joke-action
+   ```
+7. Initialize a new project:
+   ```shell
+   npm init -y
+   ```
+8. Install the **request**, **request-promise** and **@actions/core** dependencies using `npm` from the [GitHub ToolKit] (https://github.com/actions/toolkit):
+   ```shell
+   npm install --save request request-promise @actions/core
+   ```
+9. Commit those newly added files,we will remove the need to upload **node_modules** in a later step:
+   ```shell
+   git add .
+   git commit -m 'add project dependencies'
+   ```
+10. Push your changes to your repository:
+    ```shell
+    git push
+    ```
+11. Wait about 20 seconds then refresh this page (the one you're following instructions from). [GitHub Actions](https://docs.github.com/en/actions) will automatically update to the next step.

+## Step 2: Configure Your Action
+
+_Let's keep going! :bike:_
+
+### Excellent!
+
+Now that we have the custom action pre-requisites, let us create **joke-action** action.
+
+### :keyboard: Activity 1: Configure Your Action
+
+All of the following steps take place inside of the `.github/actions/joke-action` directory.
+
+We will start with using the parameters that are **required** and later implement some optional parameters as our action evolves.
+
+1. Create a new file in: `.github/actions/joke-action/action.yml`
+2. Add the following contents to the `.github/actions/joke-action/action.yml` file:
+
+   ```yaml
+   name: "my joke action"
+
+   description: "use an external API to retrieve and display a joke"
+
+   runs:
+     using: "node16"
+     main: "main.js"
+   ```
+
+3. Save the `action.yml` file
+4. Commit the changes and push them to the `main` branch:
+   ```shell
+   git add action.yml
+   git commit -m 'create action.yml'
+   git pull
+   git push
+   ```

+## Step 3: Create the metadata file
+
+_Nice work configuring your action :smile:_
+
+## Action metadata
+
+Every GitHub Action that we write needs to be accompanied by a metadata file. This file has a few rules to it, as are indicated below:
+
+- Filename **must** be `action.yml`.
+- Required for both Docker container and JavaScript actions.
+- Written in YAML syntax.
+
+This file defines the following information about your action:
+
+| Parameter   | Description                                                                                                                                            |      Required      |
+| ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------ | :----------------: |
+| Name        | The name of your action. Helps visually identify the actions in a job.                                                                                 | :white_check_mark: |
+| Description | A summary of what your action does.                                                                                                                    | :white_check_mark: |
+| Inputs      | Input parameters allow you to specify data that the action expects to use during runtime. These parameters become environment variables in the runner. |        :x:         |
+| Outputs     | Specifies the data that subsequent actions can use later in the workflow after the action that defines these outputs has run.                          |        :x:         |
+| Runs        | The command to run when the action executes.                                                                                                           | :white_check_mark: |
+| Branding    | You can use a color and Feather icon to create a badge to personalize and distinguish your action in GitHub Marketplace.                               |        :x:         |

+
+All of the following steps take place inside of the `.github/actions/joke-action` directory.
+
+Our action does not require much metadata for it to run correctly. We will not be accepting any inputs, we will however be setting a single output this time.
+
+1. Update the action metadata file `.github/actions/joke-action/action.yml` with the following content:
+
+   ```yaml
+   name: "my joke action"
+
+   description: "use an external API to retrieve and display a joke"

+
+   runs:
+     using: "node16"
+     main: "main.js"
+   ```
+
+2. Save the `action.yml` file
+3. Commit the changes and push them to GitHub:

+## Step 4: Create the JavaScript files for your action
+
+_Good job adding the metadata file! :dancer:_
+
+## Files
+
+As you probably know, in JavaScript and other programming languages it is common to break your code into modules so that it is easier to read and maintain going forward. Since JavaScript actions are just programs written in JavaScript that run based on a specific trigger we are able to make our action code modular as well.
+
+To do so we will create two files. One of them will contain the logic to reach out to an external API and retrieve a joke for us, the other will call that module and print the joke to the actions console for us. We will be extending this functionality in our third and final action.
+
+### Fetching a joke
+
+**Joke API**
+
+The first file will be `joke.js` and it will fetch our joke for us. We will be using the [icanhazdadjoke API](https://icanhazdadjoke.com/api) for our action. This API does not require any authentication, but it does however that we set a few parameters in the [HTTP headers](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers). We need to point out what those are when we get to the code, however it is outside of the scope of this course to cover HTTP in any depth.
+
+When we make our request to this API we will get back a JSON Object in the response. That Object looks like this:
+
+```
+{
+  id: '0LuXvkq4Muc',
+  joke: "I knew I shouldn't steal a mixer from work, but it was a whisk I was willing to take.",
+  status: 200
+}
+```
+
+It contains 3 key/value pairs of data that we can use in our own program or service. In our case, we are only interested in the `joke` field.
+
+**Joke Module**
+
+We will create a file named `joke.js` and it will reside in the `.github/actions/joke-action` directory.
+
+The joke module will look like this:
+
+```javascript
+const request = require("request-promise");
+
+const options = {
+  method: "GET",
+  uri: "https://icanhazdadjoke.com/",
+  headers: {
+    Accept: "application/json",
+    "User-Agent": "Writing JavaScript action GitHub Skills course.",
+  },
+  json: true,
+};
+
+async function getJoke() {
+  const res = await request(options);
+  return res.joke;
+}
+
+module.exports = getJoke;
+```
+
+Need an advanced description of the <code>joke.js</code> source code?
+
+We first bring in the `request-promise` library that we installed earlier using `npm`.
+
+Next we define a set of `options` that the `request-promise` library will use when it makes the request.
+
+Read more about [request-promise](https://github.com/request/request-promise/)
+
+Inside of the `options` block we add a key named `headers`. This defines the HTTP headers that the **icanhazdadjoke** API expects in each request that comes it's way.
+
+**icanhazdadjoke** cares the most about the keys, **Accept** and **User-Agent**, so we need to make sure we fill them in.
+
+Next we define an **asynchronous JavaScript function** to make the request for us, storing the JSON Object that is returned in a variable named `res`.
+
+Lastly, we `return` the `res.joke` which is only the value associated with the `joke` key of the JSON Object. This value will be random every time our action runs because of how we are interacting with the **icanhazdadjoke** API.
+
+This file finishes up by exporting the newly created function so that we can use it in our `main.js` file.
+
+### Creating the main entry point for your action
+
+**Main Module**
+
+We will also create a file named `main.js` that resides inside of the `.github/actions/joke-action` directory.
+
+That file will look like this:
+
+```javascript
+const getJoke = require("./joke");
+const core = require("@actions/core");
+
+async function run() {
+  const joke = await getJoke();
+  console.log(joke);
+  core.setOutput("joke-output", joke);
+}
+
+run();
+```
+
+Need an advanced description of the <code>main.js</code> source code?
+
+Like we did in the `joke.js` file, we are first going to bring in our dependencies. Only this time, our dependencies include something we wrote! To do that we simply use `require()` to point to the location of the file we wish to bring in.
+
+We also bring in `@actions/core` so that we can set the output of our action.
+
+Next we write another **asynchronous JavaScript function** that stores the return value of `getJoke()` in a variable called **joke**.
+
+Then we log the joke to the console.
+
+Finally we finish the function with by setting the contents of the joke as the value of the `joke-output` output parameter. We will use this output later in the course.
+_Don't forget to call the `run()` function._
+
+### :keyboard: Activity 1: Creating the JavaScript files for your new action.
+
+1. Create and add the following contents to the `.github/actions/joke-action/joke.js` file:
+
+   ```javascript
+   const request = require("request-promise");
+
+   const options = {
+     method: "GET",
+     uri: "https://icanhazdadjoke.com/",
+     headers: {
+       Accept: "application/json",
+       "User-Agent": "Writing JavaScript action GitHub Skills course.",
+     },
+     json: true,
+   };
+
+   async function getJoke() {
+     const res = await request(options);
+     return res.joke;
+   }
+
+   module.exports = getJoke;
+   ```
+
+2. Save the `joke.js` file.
+3. Create and add the following contents to the `.github/actions/joke-action/main.js` file:
+
+   ```javascript
+   const getJoke = require("./joke");
+   const core = require("@actions/core");
+
+   async function run() {
+     const joke = await getJoke();
+     console.log(joke);
+     core.setOutput("joke-output", joke);
+   }
+
+   run();
+   ```
+
+4. Save the `main.js` file.
+5. Commit the changes to this branch and push them to GitHub:
+   ```shell
+   git add joke.js main.js
+   git commit -m 'creating joke.js and main.js'
