 # Build Instructions
 This project fully supports Linux today.
-Support for Windows is for the loader and layers (additional info below).  Additional Windows support will be coming in Q1'15.

 Windows 7+ with additional, software:
 
 - Microsoft Visual Studio 2013 Professional.  Note: it is possible that lesser/older versions may work, but that has not been tested.
-- CMake (from http://www.cmake.org/cmake/resources/software.html).  Note: Configure to add itself to the system PATH environment variable.
-- Python 3 (from https://www.python.org/downloads).  Note: Configure to add itself to the system PATH environment variable.
-- Cygwin (especially a BASH shell and git packages--from https://www.cygwin.com/).
+- CMake (from http://www.cmake.org/download/).  Notes:
+  - In order to build the Glave debugger, you need at least version 3.0.
+  - Tell the installer to "Add CMake to the system PATH" environment variable.
+- Python 3 (from https://www.python.org/downloads).  Notes:
+  - Select to install the optional sub-package to add Python to the system PATH environment variable.
+- Optional Packages:
+  - Qt 5.3 (from http://www.qt.io/download/).  Notes:
+    - Qt 5.3 is required in order to build the Glave debugger (GUI).  The Glave trace and replay tools can be built without Qt, but the debugger/GUI is built on top of Qt 5.3.  Various dependencies, from the Qt package are copied to the directory where the Glave debugger and its libraries are built.  In order to copy and run the debugger in another directory, these libraries must also be copied.  Other notes:
+    - While there are commercial licenses, you can also use the "Community" (free) license.
+    - By default, the installer will select the latest version (e.g. Qt 5.4) as well as some other components.  You must select "Qt 5.3"!  You can have multiple versions installed (e.g. Qt 5.2.1, 5.3, and 5.4).
+    - Installing Qt takes a long time.
+  - Cygwin (from https://www.cygwin.com/).  Notes:
+    - Cygwin provides some Linux-like tools, which are valuable for obtaining the source code, and running CMake.
+      Especially valuable are the BASH shell and git packages.
+    - If you don't want to use Cygwin, there are other shells and environments that can be used.
+      You can also use a Git package that doesn't come from Cygwin.
+  - Git (from http://git-scm.com/download/win).
