Codestrates builds on Webstrates. A web-page served from a Webstrates server is called a webstrate, and is a web-page where changes to the document object model (DOM) are persisted to the server and synchronized with other clients of the same page.
To use Codestrates you need access to a Webstrates server. Refer to the Webstrates documentation for instructions on how to set one up. To create a new codestrate on a Webstrates server check the prototypes folder for more instructions.
