### One-sentence description The [registration docs](https://gitlab.science.ru.nl/thalia/concrexit/blob/30c47a28110ab968497e059bd08fd3f44f994989/website/registrations/README.rst#L6) talk about "the HR", but the translation "Rules and Regulations" should be used. ### Current behaviour / Reproducing the bug 1. Read [the docs](https://docs.technicie.nl/master/registrations.html) 2. Dutch version of "HR" is used in an English text ### Expected behaviour Use the translation which is used in the actual document: https://thalia.nu/documents/document/65/
