# Taking courses

> Browse the course library and work through lessons.

## Course library

After signing in, the home screen shows your organization's course library. Courses are displayed as tiles with a thumbnail and title.

Tap a course to open its detail view, which shows:

* Course description
* Lesson list with progress indicators
* Estimated duration

## Working through a lesson

Tap a lesson to begin. Holos Learn opens an immersive space and loads the first stage.

Stages progress sequentially. At the end of each stage, tap **Next** to advance. Some stages may include interactive elements; follow the on-screen prompts.

### Stage types

| Type      | Description                                               |
| --------- | --------------------------------------------------------- |
| 3D object | A positioned object in your space. Rotate and inspect it. |
| Video     | A video panel anchored in your view                       |
| Text      | A text panel with instructions or explanations            |
| Image     | A static image panel                                      |

## Progress

Your progress is saved automatically. If you leave a lesson mid-way, it resumes from the last completed stage when you return.

The course library shows completion status for each course. Lessons you've finished are marked with a checkmark.

## Course authoring

Courses are built and published from the Holos dashboard. See [Authoring courses](/learn/authoring) for the full workflow, and [Skills](/dashboard/skills#generating-outputs) for how captures are turned into course content.
