## Media
### Images
```
Format: 
```
### Video
Loom, YouTube, Vimeo, and Wistia videos are embedded automatically when entered in a new line, or at the end of one. For example:
```
Video at the end of line: https://www.youtube.com/watch?v=Xe53-xzKU0U
Video in a new line:
https://www.loom.com/share/d90264426d4848be9c8112fd51841336
```
To prevent a video link from being automatically embedded, wrap it as a link like this:
```
[https://www.youtube.com/watch?v=Xe53-xzKU0U](https://www.youtube.com/watch?v=Xe53-xzKU0U)
```
Videos can also be embedded using the same syntax as images:
```

Examples:
```
### Sizing images and video
Media sizing can be done with the additional `=` option:
```
 simple, assumes units are in px
 sets the height to "auto"
 Image with width of 80% and height of 5em
```
## Links
```

## Blockquotes
```
> We're living the future so
> the present is our past.
```
## Inline code
```
I think you should use an `window.HW_config` instead.
```
## Code blocks
### Simple code block
````
```
function someFunction(arg){
if (arg){
// do something
}
}
```
