+
 An Android authenticator to be used by other andoid application and with integrated synchronisation of contacts
+
+# TODO
+
+In it's currently state it's just experimentation, did not had time to no much more.
+
+What's left and things to improve:
+
+* contact synchronisation is not finished
+
+Things to improve before being reused by other Android applications:
+
+* right now the authenticator store and provide the password in clear because that's what REST access need since XWiki itself does not provide any token based access by default
