Container Resolution

[Alepandis]

hi! i'm new using Slim, i'm working on migrate from slim v2 to slim v4, and i'm struggling with the route part, in slim v2 in the project i'm working the index file they have a list of all the includes of the different routes in different files, in v4 this is not working, and i've been trying using middleware, container following the documentation without any success, so i'm glad if you put more examples step by step.

Thanks!
