# [Greenline] Integrate grid manager in icon4py

- Shaped by:
- Appetite (FTEs, weeks):
- Developers: <!-- Filled in at the betting table unless someone is specifically required here -->

## Problem
<!-- The raw idea, a use case, or something we’ve seen that motivates us to work on this -->
We want to use the grid manager from icon4py in order access the necessary connectivity information.

## Appetite
<!-- Explain how much time we want to spend and how that constrains the solution -->
1/2 cycle to just try it out and see how far we get.

## Solution
<!-- The core elements we came up with, presented in a form that’s easy for people to immediately understand -->
make grid_man available form python and create the IconGrid from it.
involves adding a python project structure to the grid manager code and
using grid man python bindings.

add mapping from gridman ordering to icon ordering.
## Rabbit holes
<!-- Details about the solution worth calling out to avoid problems -->
Dependencies of the grid manager that we don't manage to build easily. (YAXT?, possibly other )

## No-gos
<!-- Anything specifically excluded from the concept: functionality or use cases we intentionally aren’t covering to fit the ## appetite or make the problem tractable -->

## Progress
<!-- Don't fill during shaping. This area is for collecting TODOs during building. As first task during building add a preliminary list of coarse-grained tasks for the project and refine them with finer-grained items when it makes sense as you work on them. -->
