20
21	## Workflow File Structure
22
23	Workflows are defined in `.github/workflows/` directory:
24
25	```yaml
26	name: CI Pipeline
27
28	on:
29	push:
30	branches: [main, develop]
31	pull_request:
32	branches: [main]
33
34	jobs:
35	build:
36	runs-on: ubuntu-latest
37	steps:
38	- uses: actions/checkout@v4
39	- name: Setup Node.js
40	uses: actions/setup-node@v4
41	with:
42	node-version: '20'
43	cache: 'npm'
44	- run: npm ci
45	- run: npm test
46	```
