 ## Build
 
@@ -47,17 +50,17 @@ There's no point to `purple-plugin-delta` adding the OpenSSL exemption because
 `libpurple` lacks it, and in any event, it will be unnecessary with the next
 major version of OpenSSL. So, time should resolve this for us one way or another.
 
+Significant code using the WTFPL includes the [libpurple-rust bindings](https://github.com/sbwtw/libpurple-rust)
+and the [pidgin-wechat plugin](https://github.com/sbwtw/pidgin-wechat), which
+I'm taking a lot of inspiration from. WTF I like happens to include building it
+against this mess.

 ## Use
 
 The easiest way to use this is to copy the `libdelta.so` file into
 `~/.purple/plugins`. When running pidgin, you'll now have the option to add
 a "Delta Chat" account.
 
-If it doesn't show up, chances are pidgin can't find the various shared
-libraries the .so depends on. You can run `ldd ~/.purple/plugins/libdelta.so`
-to confirm. I'll document fixing this after the build and install system is
-settled.

 At present, the "Username" and "Password" account fields correspond to email
 address and password, respectively. Many important settings also show up on the
 "Advanced" tab - if left blank, the plugin will attempt to automatically detect
