**ERROR: GIF Not Showing**

For the GIF to show, make sure that your link has the file extension at the end (.gif)

Here is an example URL of how it should look:
[https://i.imgur.com/**JL1snRo.gif**](https://i.imgur.com/JL1snRo.gif)

^^ *Notice* the ***.gif*** extension at the end

On your readme md file, the markdown should look like this:

This is most likely an issue with your outlets. Go to the outlets menu on the storyboard and verify that your outlets are connected correctly.

This can be caused when you create and delete a current outlet and create a new one.

The image below shows how an outlet is made correctly:


The second image shows an outlet that was broken (the broken outlet is the one with a warning sign :warning: next to it):
