-Extract schedule information into ICS files from Student Registration system
+A WebExtension for extracting class schedule data into ICS files.
+
+## Purpose
+
+- This project will parse the page and attempt to extract detailed and meaningful schedule information
+  from the Class Schedule registration page.
+- This project will be made for UTSA students, and maintained primarily for it, but should be available
+  generally for other systems that use the same registration system. Unfortunately, either a maintainer from different
+  systems will be required to assist, or logins need to be shared (which is, understandably, not easy).
+- Shipped as an extension, it will target Firefox first, and Chrome as well with polyfills. The project will be
+  written in TypeScript, and will be built with Webpack.
+
+## Vision
+
+- Click the extension, or a button placed somewhere on the page to activate a window for extracting data.
+- The window will provide a button for easy downloading (or a 'Save as' dialog).
+- Options will be provided to filter and modify the format of the data slightly.
+
+## Support
+
+This application targets UTSA's 'Banner Student Registration Self Service', v9.26.1.
+
+Until other class schedule systems are identified, this will be the only supported system & version.
+
+Current version can be found [here](https://ssbprod.utsa.edu/StudentRegistrationSsb/ssb/about/).
