@lcgraves Thank you so much for adding the noise videos and images!!! I have left some suggestions to help you edit the pull request so that it will pass the tests (I left the fixes for only one of the files, the comments about timecodes and credits applies to both). You can also run nom run test in terminal to see what the problems are.

You will also need to edit the index.json file for the NOC track and add the videos so they will show on the website:

content/tracks/main-tracks/the-nature-of-code-2/index.json

{
"title": "Perlin Noise and p5.js Tutorial",
"videos": ["noc/perlin/intro-to-perlin-noise", "noc/perlin/noise-vs-random", "noc/perlin/graphing-1d-perlin-noise", "noc/perlin/perlin-noise-2d", "noc/perlin/perlin-noise-detail"]
},

If you have any questions please let me know. Again, thank you so much for contributing!
