+# UnderCover
+
+https://undercover.sagev.space/ is a site designed to act as a simple interface for
+generating templated cover letters.
+
+The site is built on Flask, with a very simple VanillaJS frontend, and
+leverages LaTeX for document generation. User data, including logins and stored
+templates, is stored in postgres, with bcrypt-hashed credentials.
+
+## Deployment
+
+While not implemented as part of this repo, the site itself uses a pseudo
+blue/green deployment system, with Testing and Production both running on one
+server. A simple script toggles the proxy between pointing visitors to the blue
+or the green instance.
