How can I customize GitHub Actions for my project?

You can customize GitHub Actions by creating your own workflows in YAML files. What specific customization are you looking for?

I want to run tests on multiple versions of Node.js.

You can use the matrix strategy in your workflow file to run tests on different Node.js versions. Would you like an example?

Yes, please provide an example of the YAML configuration.

Here's a simple example:

name: Node.js CI
on: [push, pull_request]
jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        node-version: [10, 12, 14]
    steps:
      - uses: actions/checkout@v2
      - name: Set up Node.js
        uses: actions/setup-node@v2
        with:
          node-version: ${{ matrix.node-version }}
      - run: npm install
      - run: npm test
