-# nsclip
+# nsClip
+
+Simple application that removes whitespace from clipboard.
+
+## Workflow
+
+* Copy some text (``Ctrl+C``)
+* Remove whitespace (``Alt+Win+C``)
+* Paste text (``Ctrl+V``)
+
+## How does it work?
+
+The application runs in the background and when activated (``Alt+Win+C``) will strip whitespace from the current clipboard text.
+
+### Input
+
+```

+in, accumsan non quam. Nam consectetur porttitor rhoncus. Curabitur eu est et leo feugiat

+magna viverra rutrum. Cras viverra molestie urna, vitae vestibulum turpis varius id.
