 <p>On Windows, it is important that you pay attention to the instructions in the <a href="#special-considerations">Special Considerations</a>.</p>
 <p>Windows is the only non-POSIX OS supported by the JDK, and as such, requires some extra care. A POSIX support layer is required to build on Windows. Currently, the only supported such layers are Cygwin and Windows Subsystem for Linux (WSL). (Msys is no longer supported due to a too old bash; msys2 would likely be possible to support in a future version but that would require effort to implement.)</p>

So, use <code>--with-msvcr-dll=/cygdrive/c/msvcr100.dll</code> rather than <code>--with-msvcr-dll=c:\msvcr100.dll</code>.

 <p>A functioning <a href="http://www.cygwin.com/">Cygwin</a> environment is required for building the JDK on Windows. If you have a 64-bit OS, we strongly recommend using the 64-bit version of Cygwin.</p>
 <p><strong>Note:</strong> Cygwin has a model of continuously updating all packages without any easy way to install or revert to a specific version of a package. This means that whenever you add or update a package in Cygwin, you might (inadvertently) update tools that are used by the JDK build process, and that can cause unexpected build problems.</p>

 ## Hints and Suggestions for Advanced Users
 
+### Setting Up a Repository for Pushing Changes (defpath)
+
+To help you prepare a proper push path for a Mercurial repository, there exists
+a useful tool known as [defpath](
+http://openjdk.java.net/projects/code-tools/defpath). It will help you setup a
+proper push path for pushing changes to the JDK.
+
+Install the extension by cloning
+`http://hg.openjdk.java.net/code-tools/defpath` and updating your `.hgrc` file.
+Here's one way to do this:
+
+```
+cd ~
+mkdir hg-ext
+cd hg-ext
+hg clone http://hg.openjdk.java.net/code-tools/defpath
+cat << EOT >> ~/.hgrc
+[extensions]
+defpath=~/hg-ext/defpath/defpath.py
+EOT
+```
+
+You can now setup a proper push path using:
+```
+hg defpath -d -u <your OpenJDK username>
+```
