Is this course right for my level?

Is there anything to install?

No. Every lesson runs in your own lab environment that opens in the browser.

How do lessons work?

Each lesson has 8 to 10 steps and a short quiz. Early steps show the command to type, later steps give less help; if two attempts fail, the solution opens.
