+Elite: Dangerous Market Connector
+========
+
+This app downloads commodity market data from the game [Elite: Dangerous](https://www.elitedangerous.com/) and, at your choice, either:
+
+* transmits the data to the Elite Dangerous Data Network ("EDDN") from where you and others can use it via online trading tools such as [eddb](http://eddb.io/).
+* saves the data to files on your disk which you can load into trading tools such as [Slopey's BPC Market Tool](https://forums.frontier.co.uk/showthread.php?t=53037).
+
+The user-interface is deliberately minimal - just press the "Update" button to download and automatically transmit/save the commodity market data from the station where you're currently docked in-game:

+Installation
+--------
+
+Mac:
+
+* Requires Mac OS 10.9 or later.
+* Download the `.zip` file of the [latest release](https://github.com/Marginal/EDMarketConnector/releases/latest).
+* The zip archive contains the **EDMarketConnector** app - move this app to **Applications** or wherever you want it.
+* Double-click on the app to run it.
+
+Windows:
+
+* Requires Windows 7 or later.
+* Download the `.msi` file of the [latest release](https://github.com/Marginal/EDMarketConnector/releases/latest).
+* Double-click on it.
+* The Installer will walk you through the installation process.
+* Run **EDMarketConnector** from the Start menu.
+
+
+Setup
+--------
+The first time that you run the app you are prompted for your username and password. This is the same username and password
+combination that you use to log into the Elite: Dangerous launcher. You can also choose here whether to send the market
+data that you download to EDDN, or to save it locally.
+
+You are next prompted to authenticate with a "verification code", which you will shortly receive by email from Frontier.
+Note that each "verification code" is one-time only - if you enter the code incorrectly or quit the app before
+authenticating you will need to wait for Frontier to send you a new code.
+
+If you are not prompted to authenticate, but instead see the message "Error: Invalid Credentials" then choose the menu
+option EDMarketConnector → Preferences (Mac) or File → Settings (Windows) and double-check your username and password.
+
+Uninstall
+--------
+
+Mac:
+
+* Delete the **EDMarketConnector** app.
+
+Windows:
+
+* Uninstall **EDMarketConnector** from Control Panel → Programs.
+
+
+Running from source & packaging
+--------
+The application requires Python 2.7, plus the "requests" module. Run with `python EDMarketConnector.py`.
+
+To package up for distribution requires py2app 0.9.x on Mac, and py2exe 0.6.x plus the [WiX Toolset](http://wixtoolset.org/) on Windows. Run `setup.py py2app` or `setup.py py2exe`.
