# Progress & Library

> Track progress and bookmark courses to your library.

## Your library

Bookmark any course to your **library** to keep it close for later. Bookmarking is
unlimited on every plan, including Free — so you can build a shelf of things you
want to learn without committing to them yet.

## Tracking progress

As you complete lessons, xkat records your progress automatically:

* **Per course** — see how far you are through each course you've started.
* **On the graph** — completed nodes are reflected in the
  [knowledge graph](/en/learn/knowledge-graph), so you can see your mastery at a
  glance.
* **Along your roadmap** — progress fills in as you advance through
  [MyRoads](/en/learn/roadmap).

## Picking up where you left off

Your progress is saved continuously, so you can close a lesson and return later to
resume exactly where you stopped.
