RFC: Explain conda-forge's mission

### Where should the content be added?

In a dedicated "Mission" page or "About us" page?

### What should be added?

Hello,

conda-forge is a wonderful software distribution.

Yet, there are is section in the documentation (AFAIK) mentioning conda-forge's mission / philosophy / benefits. The ["What is conda-forge?" section](https://conda-forge.org/docs/#what-is-conda-forge) mentions that:

> conda-forge is a community effort and a GitHub organization which contains repositories of conda recipes and thus provides conda packages for a wide range of software. The built distributions are uploaded to [anaconda.org/conda-forge](https://anaconda.org/conda-forge) and can be installed with [conda](https://conda.pydata.org/docs/intro.html).

but the model and the benefits of the projects aren't explained (and I am not sure that conda packages and their relevance might not be understood properly by newcomers).

I think making it explicit would help users understand the project better.

I started consolidating some notes [here](https://hackmd.io/@jjerphan/why-conda-forge), in this regards.

What do you think?

### Additional information

Originally mentioned by @matthewfeickert see [this thread](https://bsky.app/profile/matthewfeickert.com/post/3lmzmqxyans2j).

Also discussed privately with @h-vetinari who mentioned opening a RFC or issue here to continue discussions.

Start by reading the existing “What is conda-forge?” documentation section and the linked HackMD notes. Resolve whether the content belongs on a dedicated Mission page or an About us page, then document conda-forge’s model, mission, philosophy, and benefits once the proposed scope and location are agreed.
