-*** Building on Linux ***
+*** Building on Linux with Mono and XBuild ***
+
+This should be the simplest way to install EduNetworkBuilder on Linux.  You will need to install git, Mono and XBuild.
+
+On Mint or ubuntu, you can do this by running: 
+
+   $ sudo apt-get install mono-complete mono-xbuild git
+
+On Centos, you need the epel repository
+   # yum install epel-release
+   # yum install mono-complete mono-devel
+   # yum install git
+   
+After this, you should be ready to download and compile.  Determine where you want to build your source,
+cd to that directory, and run:
+
+   $ git clone https://git.solidcharity.com/timy/EduNetworkBuilder
+   $ cd EduNetworkBuilder
+   $ xbuild
+   
+After this, you should see a lot of build messages.  In the end, you should be able to find the executable
+at: EduNetworkBuilder/bin/Debug/EduNetworkBuilder.exe  Copy this file wherever you want.  For example:
+
+   $ sudo cp EduNetworkBuilder/bin/Debug/EduNetworkBuilder.exe /usr/local/bin/
+
+And then you can run it by simply typing:
+
+   $ EduNetworkBuilder.exe
+   
+*** Building on Linux  With MonoDevelop ***
 
 EduNetworkBuilder should compile on Linux using MonoDevelop with one small change to the code.
 EduNetworkBuilder on Windows uses the Microsoft deployment mechanism, which cannot build on Linux.
