-A first step to contributing is to pick from the [list of kubernetes SIGs](sig-list.md).
+* **Committees** are named sets of people that are chartered to take on sensitive topics.
+  This group is encouraged to be as open as possible while achieving its mission but, because of the nature of the topics discussed, private communications are allowed.
+  Examples of committees include the steering committee and things like security or code of conduct.
+* **Special Interest Groups (SIGs)** are persistent open groups that focus on a part of the project.
+  SIGs must have open and transparent proceedings.
+  Anyone is welcome to participate and contribute provided they follow the Kubernetes Code of Conduct.
+  The purpose of a SIG is to own and develop a set of subprojects (defined below).
+* **Working Groups** are temporary groups that are formed to address issues that cross SIG boundaries.
+  Working groups do not own any code or other long term artifacts.
+  Working groups can report back and act through involved SIGs.
