Readme Update
Update the list with all the missing projects with their name and link in a list format with proper numbering and subheadings in the readme.
You want this to be updated on the main readme or a separate readme file.
Update the current one, but keep it concise to make it less scrollable. (can be achieved by 3 or 4 projects columns in one row).
So should I only mention the main folder name and not the sub folders ?
Try to make something like this with all the project name and their links which will redirect to the project folder. Make it in alphabetical order.

Got an idea what you exactly want.
Check if this will work or I should use the names of subfolder here. @pranjay-poddar
use the name of the all the sub folders
add one more column to make it four columns
Then there will be more than 50 to 60 projects this will make the readme file so long.
yes, no problem in the long readme. The purpose of this is to showcase all the available projects in this repo.
Ok
