## Differences from Tutorials
|
|
|
|
**Tutorials** are for learning - they're comprehensive, beginner-friendly, and explain *why* you're doing each step.
|
|
|
|
**How-To Guides** are for doing - they're focused, assume knowledge, and show *how* to accomplish specific goals.
|
|
|
|
If you're new to Quagga2, start with [Tutorials](../tutorials/) instead.
