 ## Paste. ##

-This is pastebin replacement. It does not use ads, it is opensource it is relatively small.
+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.

 ### How do I get set up? ###

 This paste utilizes PDO SQLite driver, well, at least for now :) and mbstrings.
