It lets you _italicize words_ and **bold them**, too. You can ~~cross things out~~ and add __emphasis__ to your writing.

But you can also link to stuff, like [Write.as](https://write.as)!

## Organize text with headers
Create sections in your text just like this.

### Use lists
You might already write lists like this:

* Get groceries
* Go for a walk

And sometimes you need to do things in a certain order:

1. Put on clothes
2. Put on shoes
3. Go for a walk

### Highlight text
You can quote interesting people:

> Live long and prosper.

You can even share ` + "`code stuff`."
