+
+Elite Dangerous Market Connector ("EDMC") is a third-party application for use with Frontier Developments' game "Elite Dangerous". Its purpose is to facilitate supplying certain game data to, and in some cases retrieving it from, a number of websites and other tools.
+
+To achieve this it utilizes the Journal Files written by the game when played on a PC. It also makes use of Frontier's Companion API  ("Frontier's CAPI"), accessible once you've authorized this application.
+
+EDMC has a plugin system that many other developers have made use of to extend its functionality.
+
+Find out more on the [EDMC Wiki](https://github.com/EDCD/EDMarketConnector/wiki).
