+# Working Areas
+
+Much of the ongoing work and initiatives from the compiler team are performed by groups of people interested in specific areas of work. These groups of are a great way for new contributors to get involved as they provide a stream of tasks all focused around one area and have designated channels for help and advice. Here is a list of areas where work is being carried on:
+
