# Online courses with modules and lessons

> Build a course from modules and lessons. Include it in a tier, sell it for a one-off price, or both, and open modules on a schedule.

## What it does

A course is a set of modules, and each module holds lessons. Lessons can have text, images, video and audio, plus files like PDF, ZIP and EPUB.

Students work through it in a course player that keeps their progress.

## Who gets in

- Included with a tier and every tier above it.
- Bought once, for a price you set.
- Both: members get it with their tier, and anyone else can buy it.
- Or free, open to anyone, like a public post.

The outline is public, so visitors see the module and lesson titles before they pay.

## Drip modules

A module can open a set number of days after a student starts the course, so a long course arrives one step at a time.

## What it costs

Course sales go to your own Stripe account and count toward the same allowance as memberships. 0% on your first 10,000 US dollars, then 3% of each payment. Stripe's card processing fee is charged on your own Stripe account, at cost. Read [how membership fees work](https://tkvr.me/guides/membership-fees).
