+## Step 1: Setting up the project
+
+Imagine you’ve got a repetitive task you’d love to automate. You've searched through the [**GitHub Marketplace**](https://github.com/marketplace?type=actions) for existing actions that might help, you come up empty-handed…
+
+Maybe that’s because your task is a bit _too_ unique 😆
+
+**GENERATING DAD JOKES**! 🎭
+
+<img width="600" alt="dadjoke-mona" src="https://github.com/user-attachments/assets/46b6b931-8d1f-4a01-88f4-4568704039a0" />
+
+Since no pre-built action exists for your quirky automation needs, it's time to roll up your sleeves and create your own!
+
+### ⌨️ Activity: Set up your development environment
+
+Let's use **GitHub Codespaces** to set up a cloud-based development environment and work in it for the remainder of the exercise!
+
+1. Right-click the below button to open the **Create Codespace** page in a new tab. Use the default configuration.
+
+   [![Open in GitHub Codespaces](https://github.com/codespaces/badge.svg)](https://codespaces.new/{{full_repo_name}}?quickstart=1)
+
+1. Confirm the **Repository** field is your copy of the exercise, not the original, then click the green **Create Codespace** button.
+
+   - ✅ Your copy: `/{{full_repo_name}}`
+   - ❌ Original: `/skills-dev/write-javascript-actions`
+
+1. Wait a moment for Visual Studio Code to load in your browser.
+
+1. Verify that **Node.js** is available by opening a terminal and running:
+
+   ```sh
+   node --version
+   npm --version
+   ```
+
+   <details>
+   <summary>Having trouble? 🤷</summary><br/>
+
+   - Make sure you selected your personal copy of the repository, not the original template.
+   - If the Codespace fails to start, try refreshing the page and creating a new one.
+   - Node.js and npm should be pre-installed in the development environment.
+
+   </details>
+
+### ⌨️ Activity: Initialize Project
+
+Now that your Codespace is ready, let's initialize a new Node.js project and install the dependencies needed for your Dad Jokes action.
+
+1. Within your GitHub Codespace terminal window initialize a new project:
+
+   ```sh
+   npm init -y
+   ```
+
+1. Install the required dependencies:
+
+   ```sh
+   npm install request request-promise @actions/core @vercel/ncc
+   ```
+
+   > 🪧 **Note:** You will learn each library purpose in the next steps
+
+1. Review `package.json` to confirm dependencies are listed in the `dependencies` section.
+
+1. Open the `.gitignore` file and add an entry to exclude the `node_modules` directory from being tracked by Git:
+
+   ```text
+   node_modules/
+   ```
+
+   We don't want to commit `node_modules` because it contains thousands of files that would bloat the repository. 
+
+   > 🪧 **Note:** Instead, later in the exercise you will bundle your action into a single JavaScript file with all dependencies included.
+
+1. Commit and push your changes:
+
+   ```sh
+   git status
+   git add .
+   git commit -m "Initialize project"
+   git push
+   ```
+
+1. With the changes pushed to GitHub, Mona will check your work and share the next steps.
+
+<details>
+<summary>Having trouble? 🤷</summary><br/>
+
+- Ensure you are at the repository root before running `npm init -y`.
+- Do not commit `node_modules/` to the repository; ensure it's listed in `.gitignore`.

+## Step 2: Create Source Files & Run Locally
+
+Nice! Now that we have the project initialized and dependencies installed, it's time to create the source files for your Dad Jokes GitHub Action.
+
+### 📖 Theory: The GitHub Actions Toolkit
+
+The `@actions/core` library is the main library from the [GitHub Actions Toolkit](https://github.com/actions/toolkit), a collection of packages for building JavaScript GitHub Actions. It provides essential methods to interact with the GitHub Actions runtime environment, accept action inputs, and produce outputs for other workflow steps.
+
+> [!TIP]
+> The [GitHub Actions Toolkit](https://github.com/actions/toolkit) includes other useful libraries like `@actions/github` for interacting with the GitHub API and `@actions/artifact` for uploading and downloading artifacts. 
+> 
+> Visit the [actions/toolkit](https://github.com/actions/toolkit) repository for more.
+
+
+### ⌨️ Activity: Implement the Dad Jokes Action
+
+Let's create the source files and implement the logic for your action.
+
+1. Create `src/` directory to hold your JavaScript files:
+
+1. Create `src/joke.js` file to hold the logic for fetching a joke from the `icanhazdadjoke.com` API:
+
+   ```js
+   const request = require("request-promise");
+
+   const options = {
+     method: "GET",
+     uri: "https://icanhazdadjoke.com/",
+     headers: {
+       Accept: "application/json",
+       "User-Agent": "Writing JavaScript action GitHub Skills exercise.",
+     },
+     json: true,
+   };
+
+   async function getJoke() {
+     const res = await request(options);
+     return res.joke;
+   }
+
+   module.exports = getJoke;
+   ```
+
+   The `getJoke` function makes an HTTP GET request to the `icanhazdadjoke.com` API and returns a random dad joke.
+
+   We export the `getJoke` function so it can be used in other files.
+
+1. Create `src/main.js` that will be the main entry point for your action:
+
+   ```js
+   const getJoke = require("./joke");
+   const core = require("@actions/core");
+
+   async function run() {
+     const joke = await getJoke();
+     console.log(joke);
+     core.setOutput("joke", joke);
+   }
+
+   run();
+   ```
+
+   We call the `getJoke` function and follow up with `core.setOutput()` to set the `joke` output of your GitHub Action.
+
+1. Run the action locally to verify it works:
+
+   ```sh
+   node src/main.js
+   ```
+
+1. Commit and push:
+
+   ```sh
+   git add src/
+   git commit -m "Add Dad Joke action source files"
+   git push
+   ```
+
+1. With the changes pushed to GitHub, Mona will check your work and share the next steps.
