### Git context
You can build from Git directly without [`actions/checkout`](https://github.com/actions/checkout/) action,
even in private repositories if your `context` is a valid Git url:
```yaml
name: ci
on:
pull_request:
branches: master
push:
branches: master
tags:
jobs:
git-context:
runs-on: ubuntu-latest
steps:
-
