How to make custome snippet for add resources and template variable by default.

Hello Everyone

I am working on modx project. I want to make custom extra addon in it and after installing extra in modx resources and tvs are automatically install in it.

I Want it for searching Products with individual category.

If it's simple, look at the PackMan extra. If not, check out MyComponent.
