+## How it works?
+
+- Makes your media content available locally to the devices on the same network.
+
+- Attempts to figure out your PC's local IP address.
+
+- Makes a network request to Kodi server to play the media content that it just hosted on your local network.

-- This tool is supposed is supposed to be very minimal way to play local and network files on Kodi. I made it to end those awkward moments when you are unable to quickly play your local media to Kodi while everybody watches you in awe.

You don't want to setup FTP/SMB (if not already), add it as a network source on Kodi and locate the media to just make it play.
