How to compile from source?

Hi all,

inside this thread https://forum.opensearch.org/t/custom-logo-on-opensearch/6211 I can see a suggestion about make the changes and then compile from source.
Could please anyone explain me how to proceed? If I would like to change the background color (let me set green :D) I have to change wich css file? And then, how I can compile from source?

Thanks a lot in advance

Start at the Dashboards developer guide:

Then once you’ve got everything bootstrapped, I think you’ll need to do yarn build instead of yarn start.
