+
+
+With this plugin Gerrit can use OAuth2 protocol for authentication.
+Supported OAuth providers:
+
+* [AirVantage](https://doc.airvantage.net/av/reference/cloud/API/#API-GeneralInformation-Authentication)
+* [Bitbucket](https://confluence.atlassian.com/bitbucket/oauth-on-bitbucket-cloud-238027431.html)
+* [CAS](https://www.apereo.org/projects/cas)
+* [CoreOS Dex](https://github.com/coreos/dex)
+* [Facebook](https://developers.facebook.com/docs/facebook-login)
+* [GitHub](https://developer.github.com/v3/oauth/)
+* [GitLab](https://about.gitlab.com/)
+* [Google](https://developers.google.com/identity/protocols/OAuth2)
+* [Keycloak](http://www.keycloak.org/)
+* [Office365](https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-v2-protocols)
+
+See the [Wiki](https://github.com/davido/gerrit-oauth-provider/wiki) what it can do for you.
+
+Prebuilt artifacts
+------------------
+
+Prebuilt binary artifacts are available on [release page](https://github.com/davido/gerrit-oauth-provider/releases). Make sure to pick the right JAR for your Gerrit version.
+
+Build
+-----
+
+To build the plugin with Bazel, install
+[Bazel](https://bazel.build/versions/master/docs/install.html) and run the
+following:
+
+```
+ git clone https://gerrit.googlesource.com/plugins/oauth gerrit-oauth-provider
+ cd gerrit-oauth-provider && bazel build gerrit-oauth-provider
+```
+
+Install
+-------
+
+Copy the `bazel-genfiles/oauth.jar` to
+`$gerrit_site/plugins` and re-run init to configure it:
+
+```
+ java -jar gerrit.war init -d <site>
+ [...]
+ *** OAuth Authentication Provider
+ ***
+ Use Bitbucket OAuth provider for Gerrit login ? [Y/n]? n
+ Use Google OAuth provider for Gerrit login ? [Y/n]?
+ Application client id : <client-id>
+ Application client secret :
+ confirm password :
+ Link to OpenID accounts? [true]:
+ Use GitHub OAuth provider for Gerrit login ? [Y/n]? n
+```
+
+Reporting bugs
+--------------
+
+Make sure to read the [FAQ](https://github.com/davido/gerrit-oauth-provider/wiki/FAQ) before reporting issues.
