+This is pastebin replacement. It does not use ads, it is opensource, it is relatively small.
 And it has minimal pastebin API stub, at least pastebinit can paste to it with minimal config changes.
 Besides pastebinit there are 2 cli clients available on main page of this app.
 
+And as a bonus this app can short links too! But it either shorts links **or** stores paste, not both at same time.

+### TODO ###
+
+* Make one app that shorten links, stores paste, stores pictures (yes! image hosting).
+* Configurable features (not everyone wants all features enabled).
+* Before implementing picture storage, there should be made authorization.
+* Sane and clear API.
