 peroxide
 ========
 
-Peroxide aims to be a clone of the Proton Bridge free of all the bloatware that
-makes things easy for casual Windows users, but makes power users cringe. The
-goal is to make it:
+Peroxide is a fork of the [ProtonMail bridge][1]. Its goal is to be much like
+[Hydroxide][2] except with as much re-use of the upstream code as possible. The
+reason for the re-use is to ensure that the changes to the service APIs can be
+merged in as fast and as easily as possible. At the same time, Peroxide aims to:
 
- * buildable with simple `go build`
- * runnable as a systemd/launchd/whatever service
- * easy to merge the upstream changes to the communication protocol
+ * run as a server providing data access using standard protocols, so that a
+   wide variety of devices can use their native productivity tools instead of
+   ProtonMail's proprietary ones
+
+ * implement features that are missing from the upstream version because they
+   are hard to make work with Outlook
+
+ * make things easy to hack on without a deluge of dependencies providing little
+   value in the context of the two above points
+
+To than end, Perixide:
+
+ * is buildable with `go build`
+ * drops the original GUI and CLI
+ * drops all the desktop desktop integration and trackers
+ * provides a server program and a separate configuration program
