Installation Guide

Step 1: Create a GitHub Actions Workflow File

To get started with GitHub Actions, you need to create a workflow file in your repository. This file will define the tasks that you want to automate.

To create a workflow file, follow these steps:

1. In your repository, navigate to the .github/workflows directory.
2. Create a new file with a .yml extension, for example, main.yml.
3. In the file, specify the name of the workflow and the triggers that will activate it.

Step 2: Define the Workflow Tasks

Once you have created the workflow file, you need to define the tasks that you want to automate.

To define tasks, follow these steps:

1. In the workflow file, specify the tasks that you want to automate, using the steps keyword.
2. For each task, specify the action that you want to perform, using the action keyword.
3. Specify any inputs or outputs that are required for the task.

name: Build and Test
on:
  push:
    branches:
      - main
jobs:
  build-and-test:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2
      - name: Setup Node.js
        uses: actions/setup-node@v2
