 # Upstream contribution policy
 
 conda-store builds on top of several open source libraries, and critically, many projects in the conda ecosystem.
-Contributing back to upstream projects good open source citizenship and the conda-store development team aims to do so wherever relevant.
+Contributing back to upstream projects shows good open source citizenship and the conda-store development team aims to do so wherever relevant.
 This policy document outlines some best practices and considerations for upstream contributions.
 
 ## Upstream first
 
-As the grounding principle, always prefer contributing features or patches to upstream projects before implementing workarounds or developing conda-store-specific solutions.
-This helps us develop better and more sustainable solutions that can benefit a larger community.
-If you can unsure about when or how to contribute, open an issue in any conda-store repository and mention the [`@conda-incubator/conda-store`](https://github.com/orgs/conda-incubator/teams/conda-store) team for input.
