Names of the projects and lessons do not match the course names.

[longtimedeveloper]

1. Names of the section folders do not match the section names in Unity.

To make it much simpler and and very professional I would:

Name sections with each name with two digits so that the are sorted by section number:

section_1 now becomes section_01
section_2 now becomes section_02
...
section_12 now becomes section_12

However, I recommend these names instead to make the names match Udemy:

section_1 now becomes Section_01_GettingStarted
section_2 now becomes Section_02_Fundamentals
...

These names will be listed alphabetically, same as Udemy.

2. Project names are nested but don't have to be.

KeyboardInput/KeyboardInput could be KeyboardInput. When you create the project, select the option to, place solution in the same directory as the project. Doing this will make the lesson listing much cleaner without the duplicating of the lesson name in GitHub.

Also, naming the project so that the Udemy lesson number is indicated in the project title so that the projects sort alphabetically.

S2_07_SayingHello
S2_08_VariablesAndDataTypesPart1
...

Now the project names are very easy to quickly locate within a section..

Please don't take this as criticism, just a fellow wanting to be able to quickly find the resource he is look for.

Have a nice day, Karl
