Issues and Pull Requests were not migrated to the new organization/repository, so `matrix-org/synapse/pull` and `matrix-org/synapse/issues` references were kept as-is. `matrix-org/synapse-s3-storage-provider` references were also kept, as that module still continues living under the `matrix-org` organization. This patch mainly aims to change documentation-related things, not actual usage in full yet. For polish that, another more comprehensive patch is coming later.

# Overview
|
|
Captcha can be enabled for this home server. This file explains how to do that.
|
|
The captcha mechanism used is Google's [ReCaptcha](https://www.google.com/recaptcha/). This requires API keys from Google. If your homeserver is Dendrite then [hCapcha](https://www.hcaptcha.com) can be used instead.
|
|
|
|
