+# Slackgmote
+
+Slackgmote is a small utility that depends on imagemagic and converts animated gifs to slack emoji.
+It supports cropping them as well. Output will always meet slack standards and be named: 
+`original_name_crop_slack.gif`
+
+It is currently poorly written, not efficient, and has no tests. Feel free to re-write this in some
+better way (like as a gem or something) and open a merge request. Or not. Whatever.
+
+## Usage
+
+`slackgmote path/to/gif.gif [WidthxHeight+offset+offset]`
