 ## Reference
 
 This Fastify plugin decorates the fastify instance with the [`simple-oauth2`](https://github.com/lelylan/simple-oauth2)
-instance inside a **namespace** specified by the property `name`.
+instance inside a **namespace** specified by the property `name` both with and without an `oauth2` prefix.
 
 E.g. For `name: 'customOauth2'`, the `simple-oauth2` instance will become accessible like this:
 
-`fastify.customOauth2.oauth2`
+`fastify.oauth2CustomOauth2.oauth2` and `fastify.customOauth2.oauth2`
 
 In this manner we are able to register multiple OAuth providers and each OAuth providers `simple-oauth2` instance will live in it's own **namespace**.
 
 E.g.
 
-- `fastify.facebook.oauth2`
-- `fastify.github.oauth2`
-- `fastify.spotify.oauth2`
-- `fastify.vkontakte.oauth2`
+- `fastify.oauth2Facebook.oauth2`
+- `fastify.oauth2Github.oauth2`
+- `fastify.oauth2Spotify.oauth2`
+- `fastify.oauth2Vkontakte.oauth2`

 ## Provider Quirks
 
 The following providers require additional work to be set up correctly.
