 # Installing GenI
 
+## Command line interface and server
+
 (tested on Linux, Windows, and MacOS X)
 
-Install the basic version first
+1. Install the [Haskell Platform][haskell-platform]. GenI 0.24 is known
+   to build with either haskell-platform-2013.2.0.0 and
+   haskell-platform-2012.2.0.0.  Other versions may work too.
 
-    cabal install
+       If you want the graphical interface, and you are on a 64-bit Mac,
+   take the 64-bit version of the Haskell Platform.
 
-Try installing the graphical interface
+2. Install the basic version first. If you just want the
+   last stable release of GenI,
 
-    cabal install ./geni-gui
+           cabal install GenI geniserver
 
-You may run into some trouble with wxHaskell.
-Get in touch if that's the case.
+       However, if you want to install the unstable version
+   from source, change to the directory this README is in
+   and
 
+           cabal install . ./geniserver
+
+## Graphical interface
+
+1. Install wxWidgets.  If you have a 64-bit Mac, install the Cocoa
+   interface. If you use HomeBrew on Mac, `brew install wxmac` should do
+   the trick.
+
+       GenI 0.24 has been known to work with wxWidgets 2.9.4 on MacOS X, and
+   is expected to work on wxWidgets 2.8.x or wxWidgets 2.9.x on Linux.
+
+2. Install wxHaskell (potentially painful)
+
+           cabal install wx
+
+       If you run into trouble here, you may need to use a development
+   version of [wxHaskell][wxHaskell].
+
+3. Install the graphical interface (should be easy if 2 went well)
+
+           cabal install ./geni-gui
+
+4. Try GenI (needs GenI examples files from this repository)
+
+           cd examples/ej
+           geni-gui -t trees -l lexicon -s suite
+
