Hi @mamtawardhani,

Thank you for checking! I noticed that in some of the recent PRs there hasn’t been a second reviewer before merging. Could you please clarify the current process for reviews? Also, could you let me know roughly how long it might take for this PR to get merged?

If possible, I’d really appreciate it if this could be merged on priority — I’ve been contributing to Codecademy Docs since 2023.

Thanks!
