DIY.md not being found.

Describe the bug
The .md detailing the instructions on how to make your own seems to be broken. I am very, very new to a lot of this stuff, but it shows the link to the file in the repo but then its not found. Is there a way I could get that information? Thanks!

To Reproduce
Steps to reproduce the behavior:

1. Go to 'README.md'
2. Click on 'DIY.md'
3. See error

Apologies if this is something silly I am misunderstanding, but I can view the install file just fine!
