Begginers at Drupal (such as myself) find it very hard to find information on how to properly apply in code and find detailed information on Form Elements and Render Elements. Most of the time we have to outsource to Stack Overflow and similar websites to find what we are looking for.

Improve the Classes documentation found in Form and render elements to make them more detailed about properties and attributes;
Improve Form render elements → and/or Form API → ;

[x] Decide on the scope of the issue, improve @docblocks and/or Form API guide;
- Both will be improved;
[x] Decide on the Documentation template, we worked on this Google Doc:
- The template proposed it is the one to be used on @docblocks;
[x] Decide where the guides will be placed inside the Wiki;
[x] Create another [Meta] issue to keep track of each element improvement;
[ ] Map other issues related to this in the comments, validate if they are truly related and link them as child to this issue;
