Hi guys,

I'm happy to contribute to this issue too (I did #22). Let me know how, and if I can help.

Hi guys,

I just created a pull request #357 that adds support for chroma. Please have a look. In addition, I have three notes.

First, the embedding and config module need refactoring. There is a lot of boilerplate code that is unnecessarily repeated, for example.

Second, the embedding stores need be tested more thoroughly. I added a bunch of TODO to the chroma test case.

And finally, I hope I did not anger anyone by rushing forward.

I think this issue can be closed, since my PR #357 has been merged.

My first point about refactoring should be carried over to another Issue.

CLOSED - Well done!
