The document discusses using server-sent events (SSE) with HTML5 to push data from a server to a client browser. It provides tools and guidelines for a project to build a TODO list application that uses SSE to continuously update the list of TODOs in the browser. The project skeleton outlines the TODOs API on the server and resources for further information on SSE and localStorage APIs used in the project.
