# Protobuf Global Extension Registry

This file contains a global registry of known extensions for descriptor.proto,
so that any developer who wishes to use multiple 3rd party projects, each with
their own extensions, can be confident that there won't be collisions in
extension numbers.

If you need an extension number for your custom option (see [custom options](
https://developers.google.com/protocol-buffers/docs/proto#customoptions)),
please [send us a pull request](https://github.com/protocolbuffers/protobuf/pulls) to
add an entry to this doc, or [create an issue](https://github.com/protocolbuffers/protobuf/issues)
with info about your project (name and website) so we can add an entry for you.
