# About this branch

Our goal is to run [upstream] OSEM without modifications to its codebase. We currently still make a few modifications in this transitional branch:

${items[*]}

These divergences from upstream should be seen as a to-do list, where completing an item means either solving its need in a general way upstream, or adjusting our procedures to accommodate upstream’s existing capabilities or limitations.

## Guidelines

Don’t develop on this branch. It follows upstream by regularly **rebasing** the above modifications. When a modification is no longer necessary, it will be dropped during the rebase. When there are no remaining modifications, this branch will be deleted.
