Hello! Thank you for your PR.

Merging this PR won't work without some obvious modifications.

• The original repository itself clearly doesn't support localization. At least not in English. I can't yet imagine how non-native users will read Docs.

• Also, this looks a bit like advertising. I think you should create a separate section or subsection like "Community Utilities" and explicitly mention your product there. I think it will be compromize.

• I also think this section needs to be synchronized with other localizations. In that case, it would be better to merge it into the development branch. So that if it's approved, we can translate it into other languages.

Best regards.
