+This is Tlen.pl protocol plugin for Pidgin.
+
+There used to be an official website at <http://nic.com.pl/~alek/pidgin-tlen/> but now it is here, on github.
+
+What is supported:
+
+ * IMs
+ * Adding/removing users from roster (user list stored on server)
+ * Setting/changing status
+ * Typing notifications
+ * New email notifications
+ * Multiuser chat + conferencing
+ * Public directory (setting info about yourselves, searching for buddies)
+ * Whiteboard sessions (this is not a part of the original protocol, works
+   between pidgin clients only)
+ * avatars (just for buddies; user avatar is not supported yet)
+
+Installation instructions for Windows users (TODO: test, fix, doesn't it work?)
+
+ * copy libtlen.dll to c:\Program Files\Pidgin\plugins directory
+ * for each tlen_XX.png file copy it to relevant directory:
+		c:\Program Files\Pidgin\pixmaps\pidgin\protocols\XX\tlen.png
+		
+
+My kudos to
+
+ * Krzysztof Godlewski <<sigsegv@tlen.pl>> -- chats, whiteboard, fixes
+ * Adam Mazur <<ghr@o2.pl>> -- resurecting project after years of inactivity ;-)
