Thank you very much for your contribution to the documentation! Due to the way
Docusaurus versioning works, you need to make the
changes in two locations:

• docs/versioned_docs/version-v{version}/path/to/file
• docs/docs/path/to/file

Without making them in both locations, the changes will most likely be lost when
releasing another version. Thank you! :)

@zepatrik see latest commit. I updated docs up until 1.9, since the oryd->ory change seems to have happened in 1.9.1 (https://github.com/ory/hydra/blob/master/CHANGELOG.md#191-2021-01-27)
