-## Demo
-Type `cabal run example` to launch a local server with cookie
-authentication at 8080 port. It's a simple three-paged web site that
-will show the private page only if a correct cookie is presented. For
-valid accounts see `usersDB` list in `example/Main.hs`.
-
-## Known limitations (for versions below v0.5.0)
-Renewal of a `ServerKey` immediately invalidates existing sessions, thus is not recommended to use frequently.
-Restarting an application with key renewal will result in the same effect.
