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 defines the automation workflow that you want to execute. To create a workflow file, follow these steps:
- Navigate to your repository on GitHub.
- Click on the Actions tab.
- Click on the New workflow button.
- Select the Blank workflow file template.
- Name your workflow file (e.g., main.yml).
- Define your workflow by adding jobs and steps.
Step 2: Configure Your Workflow
Once you have created your workflow file, you need to configure it to automate your software delivery pipeline. You can configure your workflow by adding jobs and steps, and by defining the triggers and conditions for your workflow.
For example, you can add a job to build and test your code, and another job to deploy your software to production. You can also define triggers and conditions to control when your workflow is executed.
