 # Policies and Procedures
 
 This section describes how Maker Space is managed.
+
+## New Members
+
+When joining Maker Space, new members start by filling in an application form which can be found here: [https://www.makerspace.org.uk/joinus/](https://www.makerspace.org.uk/joinus/)
+
+The [New Member Procedure](./new_member_procedure/) explains the process in more detail.
+
+The last step of becoming a member of Maker Space is to go through a general [induction](./induction/).
+This covers the basic health and safety points, where to find things, what to expect of the space and what we expect of you.
+
+## Making changes in the space
+
+Maker Space members are welcome to make and suggest changes in the space. 
+We have a [Change Proposal Procedure](./proposals/) for proposing and making changes in the space.
+
+## Becoming a Keyholder
+
+Most Maker Space members are keyholders, giving them 24hr access to the space.
+Our [Keyholder Policy](./keyholder_policy/) outlines what we expect of you as a keyholder.
+
+To become a keyholder, you must be sponsored and seconded by existing keyholders and go through the [Keyholder Proposal Procedure](./keyholder_proposal/).
+
+## Behaviour Policies
+
+Please, just be nice.  We don't want to have to use our [Code of Conduct](./code_of_conduct/) or our [Grievance Procedure](./grievance_procedure/).
