 the user themselves has submitted, or has already commented on.
 
 
+### features
+
+By default, `fedora-update-feedback` queries bodhi for updates for the current
+release that are in the `testing` state.
+
+Some additional options can be set either on the command line, or in a
+`[fedora-update-feedback]` section in the `~/.config/fedora.toml` configuration
+file.
+
+With the `--check-pending` CLI switch or the `check-pending = true`
+configuration option, updates in the `pending` state are also queried (for
+example, if the user has manually installed builds from koji and wants to give
+bodhi feedback for those as well). 
+
+Additionally, with the `--check-obsoleted` and `--check-unpushed` flags (or
+the `check-obsoleted = true` and `check-unpushed` configuration options),
+`fedora-update-feedback` will check if any lingering builds from unpushed
+or obsoleted updates are still installed locally.
+
+With the `save-password = true` configuration option, `fedora-update-feedback`
+will attempt to securely save the FAS password in the login keyring, so it
+does not have to be entered every time. To ignore or overwrite a stored
+password, use the `--ignore-keyring` CLI switch. 
+
+This information is also printed when running `fedora-update-feedback --help`.
