+# Contributing to SIG Autoscaling
+
+The best place to find information and resources to be able to participate and support SIG Autoscaling's work is to visit the Autoscaling Special Interest Group [Github repo](https://github.com/kubernetes/community/tree/master/sig-autoscaling) and the [README](https://github.com/kubernetes/community/tree/master/sig-autoscaling) file.
+You can also learn more about the [SIG Autoscaling Charter](https://github.com/kubernetes/community/blob/master/sig-autoscaling/charter.md) following the link.
+
+## Getting started
+Joining the [mailing list](https://groups.google.com/forum/#!forum/kubernetes-sig-autoscaling) will get you invited to the general SIG meetings.
+
+Our Regular SIG Meeting is Mondays at 16:00 CET (Central European Time). This is a general forum for wider issues as well as most of the subprojects.
+
+Most of the work of the SIG is undertaken by our [Subprojects](https://github.com/kubernetes/community/tree/master/sig-autoscaling#subprojects) where new contributors are always welcome. Some of the subprojects have their own dedicated meetings - either on an ad-hoc basis, or organised more regularly. See the above link and each subproject's Slack channel for more details.
+
+Contributions are made via Pull requests.  Before opening a pull request, contributors must sign the [CNCF Contributor License Agreement](https://github.com/kubernetes/community/blob/master/CLA.md)
+
+
+## Questions about contributing
+Feel free to ask any questions in the [#sig-autoscaling](https://kubernetes.slack.com/messages/sig-autoscaling) 
+Slack channel through the Kubernetes Slack. To get a Slack invite, visit http://slack.k8s.io/ . Once you're logged you can join the channel. Alternatively, you can join any of our meetings.
