-<h3>B. Installing Cygwin (Legacy)</h3>
-<p>
-  Cygwin is a lightweight POSIX environment that provides the minimum
-  requirements needed for a Windows client PC to run Murfey . However, it does
-  not support building and installing packages which have been written in Rust,
-  which many modern Python packages, including Murfey's dependencies, now make
-  use of. It is still possible to install and run Murfey via Cygwin, but older
-  versions of its dependencies will have to be installed.
-</p>
-<p>
-  To install, download the Cygwin setup executable using this
-  <a href="{{ proxy_path }}/cygwin/setup-x86_64.exe">mirror</a>, and then run
-  the following from a terminal (both Command Prompt and Windows Powershell
-  work):

-</pre>
-<p>
-  This will install Cygwin with the minimum packages needed to run Murfey. The
-  Cygwin install command will occasionally hang after completion. In such an
-  event, just hit Enter to return to a normal command prompt window.
-</p>
-<p>
-  If you already have a Cygwin install that you would like to preserve, rename
-  it so that it doesn't get overwritten (something like "cygwin64-old") before
-  running the command line above.
