Thank you for showing interest in helping your fellow apprentices learn by providing additional resources that you found and believe would be of use to someone else as well.
If you are new to GitHub I recommend watching this video by freecodecamp and trying this tutorial by firstcontributions.
When contributing please use the markup language known as MARKDOWN, watch this video for more information on that.
Each of the folders in this repository corresponds to its respective module in the apprentice learning path for Application Developers. Whenever you come across learning material that you'd like to share, make a pull request to the folder you choose to contribute to and add it to that folder's .md file using the MARKDOWN format.
