+Repository: https://github.com/coala/corobo
+
+corobo is a collection of [errbot](http://errbot.io) chatbot framework plugins.
+
+The primary objective of this project is to improve corobo by solving as many
+pending issues as possible along with introducing new plugins which will ensure
+smooth functioning in the community.
+
+It is also necessary to implement better configuration for the bot and
+eliminate the use of environment variables which is hacky and a better
+solution is possible.

+
+#### Improvements which can be made to the existing plugins:
+
+    - Adapt LabHub plugin to use the most recent release of IGitt.
+    - Deprecate use of github3 and migrate plugins to use IGitt.
+    - Handle users with different GitHub and GitLab usernames.
+    - Delay loading GitHub org member list when not needed.
+    - Implement changes to handle other backends (Eg. Zulip).
+    - Currently, the use of DefaultConfigMixin is not the best solution for
+      configuration. Implement a solution so that other orgs won't need the
+      Mixin while configuring their plugins.
+    - Convince at least one other organization to use corobo in their chat room.
+    - Implement/Modify plugins to make handling of events like GCI/GSoC easy.
+
+```
+Eg:
+>corobo set current event GCI
+@/all, GCI has been started, so you can’t assign GCI related issues until the event ends.
+```
+
+#### New plugin ideas:
+
+    - Plugin for corobo Usage Stats.
+    - Congratulate people who have their first commit merged.
+    - Listen for invite acceptance and provide more info based on that.
+    - Plugin for voting.
+    - All short and partial issues/PR URIs.
+    - Plugin to remove labels from issues. 
+
+```
+Eg:
+>corobo remove label area/gci from coala/corobo 
+@user, successfully removed area/gci label from 10 issues in coala/corobo
+```
