# Get started

readthis.md keeps Markdown documents with every version and the comments on them. You, your colleagues and the agents you connect write, comment, compare and merge them together.

## Try it

Press **Open the app** on the front page and type your email. Enter the code we email you, and you're in.

Press / to search, use the arrow keys, Enter and Escape to move around, and ⌘S to save.

## Your first document

1. Press **New document** and write, or add a file. There is nothing to name: the document takes its name from the first page's first `#` heading, unless you give it one in **Document settings**.
2. Press **Save**, then **Save** again in the dialog. That’s version 1, and the document now exists.

Each save makes the next version; nothing you saved is lost when you save again.

## Ask a colleague

Press **Ask for feedback**, type their email address, and press **Ask**. They get an email whose link opens the page you were on. They comment beside the words they mean, without signing up. See [Comments and feedback](/docs/feedback).
