[REQ] Add Description to generators

Is your feature request related to a problem? Please describe.

When browsing the available generators and navigating to the detail page no description of the generator is given (or information on how to use it in your application).

Describe the solution you'd like

Add some information to these pages, especially:

• some basic information on what is generated
• Requirements that should be fulfilled to use the code generated
• how it should be used in your application
• how it can not be used and possible workarounds
• +current bugs
• (Maybe an example command to generate it, although that's covered by the general guide, but it makes life easier to just copy a command)

I am highly motivated to add this information to the generators listed below but would welcome a discussion about the structure or any other information missing.

Additional context

While looking for a generator for my new node-js backend I tried several generators, namely

• typescript-node, which I could not get to work, because I was to lazy to find out which other packages I would need to install (this isn't mentioned anywhere)
• typescript-rxjs, which does not work out-of-the-box with node-js
• typescript-axios, which finally worked because the name already says what to install :)

Start with the available generators page and its linked generator detail pages, especially the TypeScript Node, TypeScript RxJS, and TypeScript Axios entries. Review the existing page structure and generator requirements before proposing a consistent documentation format. Done means the selected pages explain what they generate, required dependencies, known limitations or bugs, and an example command.
