Update helpers documentation

**Description**
Currently routes lacks proper import support.

**Proposed solution**
Add configurable import with sensible defaults.

**Priority**: Low/Medium

Start by locating the routes implementation and its current import handling, then read the surrounding configuration flow. Determine how configurable imports should work and what sensible defaults mean for existing routes. Done means imports work with explicit configuration and continue working with the defaults, with relevant behavior verified.
