-## EDDN - Elite: Dangerous Data Network
+# EDDN - Elite Dangerous Data Network
 
-The **Elite: Dangerous Data Network** is a system for willing Commanders to share dynamic data about the galaxy with others.  
-By pooling data in a common format, tools and analyses can be produced that add an even greater depth and vibrancy to the in-game universe.
+## About EDDN
+Elite Dangerous Data Network is a tool that facilitates the players of the game
+[Elite Dangerous](https://www.elitedangerous.com/), including its 
+expansions, sharing data about the game galaxy with others.
+By pooling data in a common format, tools and analyses can be produced that add
+an even greater depth and vibrancy to the in-game universe.
 
-EDDN is not run by or affiliated with [Frontier Developments](http://www.frontier.co.uk/).
+EDDN is not run by or affiliated with the developer of the game - [Frontier 
+Developments](http://www.frontier.co.uk/).
 
-Hosting has been very generously provided by [Vivio Technologies](https://www.viviotech.net/), until 2017.  
-Hosting is now provided by the [EDCD community](https://edcd.github.io/).
+The live EDDN service itself does not store any data, and thus makes no 
+archive or "current state" available to anyone.  What it provides is a
+stream of live data to any interested parties.  Some of those then make 
+aggregated data available for general use.

+
+## Using EDDN
+### Game players
+If you are a player of the game and only want to help out by sharing the 
+data available to you over EDDN then please consult the
+[EDCD Cmdr's Guide](https://edcd.github.io/cmdrs-guide.html).  For the most 
+part if you want to share data then you will need to be playing the game on a 
+PC, but there are some tools that utilise an API provided by the game 
+developer that can supply some data if you are playing on a console.
+
+If you're looking for tools that utilise EDDN data to enhance your experience
+then you're probably looking for one of the sites listed below.  NB: These are
+listed in name-alphabetical order and no particular ranking or endorsement is
+intended.
+
+- [EDDB](https://eddb.io/) - a website which tries to act as a database of all
+ the data available in the game. In general EDDB tries to help finding 
+ stuff which players are looking for.
+- [EDSM](https://www.edsm.net/) - originally focused on being a 'Star Map', 
+  but has since expanded its functionality.  Of particular interest to 
+  in-game explorers.
+- [Inara](https://inara.cz/) - a popular alternative to EDDB, with a lot of 
+  its own unique functionality.
+- [Spansh](https://www.spansh.co.uk/plotter) - originally this had one tool,
+  a 'Neutron Star' route plotter, but has since expanded into offering many 
+  other route plotting tools and general data searching.
+
+There are many other third-party tools for Elite Dangerous listed on
+[Elite: Dangerous Codex](https://edcodex.info/), some of which will 
+interact with EDDN.  Check the [EDDN tag](https://edcodex.info/?m=tools&cat=9).
+
+### Developers
+If you are a developer of a third-party tool that could be enhanced by 
+uploading data to EDDN then please consult
+[the live branch documentation](https://github.com/EDCD/EDDN/blob/live/schemas/README-EDDN-schemas.md)
+.
+**DO NOT** assume that any code or documentation in the `master` (or 
+any other) branch on GitHub truly reflects the current live service!
+
+### Misc
+There is also a [wiki page](https://github.com/EDSM-NET/EDDN/wiki), but its 
+contents are currently being migrated into the source code tree (so that 
+they always match the in-use code).
+
+Consult [EDDN Status](https://eddn.edcd.io/) for some information about, 
+and statistics for, the live service.
+

+
+## Hosting of the live service
+
+Hosting is currently provided by the
+[Elite: Dangerous Community Developers](https://edcd.github.io/).
