Hi, I'd like to work on this issue.

Hi @adityai0,

keep in mind that this would require some knowledge about preCICE and the documentation would need to focus on applying these tools for the preCICE events.

If this sounds good, happy to continue the discussion in a PR. But no need to pre-register any work in issues. Happy to review PRs, if they come.
