Built with CI4

I'm considering creating an additional section on a CI4 test project and would be grateful for assistance.

The idea is to allow programmers to:

1. upload details of their CI4 Projects
2. store information in a database
3. create links to each project 
4. enable comments for each project

Initially a database requires creating which would have at least two tables with the following information:

Table: Projects
id - primary index
icmx - unique link to comments table
username: varchar(128)
url: varchar(128)
notes: text (user's project notes)
details: text (project information)

Table: Comments 
id - primary index
icmx: index to project
comment: text

Once the tables are created then a Controller and Views require creating.

Looking forward to suggestions.
