# SIGs and Working Groups Most community activity is organized into Special Interest Groups (SIGs), time bounded Working Groups, and the [community meeting](communication.md#weekly-meeting). SIGs follow these [guidelines](governance.md) although each of these groups may operate a little differently depending on their needs and workflow. Each group's material is in its subdirectory in this project. When the need arises, a [new SIG can be created](sig-creation-procedure.md) ### Master SIG List | Name | Label | Leads | Contact | Meetings | |------|--------|-------|---------|----------| |[API Machinery](sig-api-machinery/README.md)|api-machinery|* [Daniel Smith](https://github.com/lavalamp), Google
