 [Delta Chat](https://delta.chat) is an instant messaging application based on
 email - which is to say, SMTP+IMAP.
 
-It doesn't have its own desktop application at present, but it does have a
-[core protocol library](https://github.com/deltachat/deltachat-core). Wrapping
-this in a libpurple plugin will allow existing desktop applications such as
-[Pidgin](https://pidgin.im) to interoperate.
+Delta has:
+
+* A mature [core library](https://github.com/deltachat/deltachat-core)
+* A mature [Android application](https://github.com/deltachat/deltachat-android)
+* An experimental [iOS application](https://github.com/deltachat/deltachat-ios)
+* An electron [desktop application](https://github.com/deltachat/deltachat-desktop)
+
+This project is a [libpurple](https://developer.pidgin.im/wiki/WhatIsLibpurple)
+plugin that wraps `deltachat-core`, allowing a number of existing desktop and
+mobile clients to send and receive IMs over SMTP+IMAP. It may be useful for
+[Linux-based mobile devices](https://source.puri.sm/Librem5/chatty), for
+GUI desktop usage **without** an Electron dependency, or console desktop usage.
+
+Current status is probably best described as "skunkworks", although connecting
+to an account and sending / receiving text messages should work reliably. You
+can view specific progress on [the issue board](https://gitlab.com/lupine/purple-plugin-delta/boards).

-There's no facility at present to import account keys, so sharing an email
