Start with library/stdtypes.po and choose one unchecked section, such as Sequence Types or Text Sequence Type. Review the surrounding translated strings and preserve the document's PO formatting while translating the selected entries. Done means the chosen section is translated and submitted as its own pull request, with the remaining work clearly separated for other translators.
