How to: 💨 Fast Builds
Earthly automatically executes build targets in parallel and makes maximum use of cache. This makes builds fast. Earthly also has powerful shared caching capabilities that speed up builds frequently run across a team or in sandboxed environments, such as Earthly Satellites, GitHub Actions, or your CI.

If your build has multiple steps, Earthly will:
1. Build a directed acyclic graph (DAG).
2. Isolate execution of each step.
3. Run independent steps in parallel.
4. Cache results for future use.
