The install docs are currently split into several top-level sections:

• Installing libmongoc via package manager
• Installing libbson via package manager
• Building on Unix
• Building on macOS
• Building on Windows (various configurations)

The Unix and macOS sections discuss how to obtain the driver sources from a release tarball, but this isn't specified for Windows. Also, some Windows-specific commands appear under the Unix section.

roberto.sanchez proposed we reorganize the documentation under the following sections:

• Getting the code
  • From Git (and generating version info)
  • Release tarball
• Building the code
  • Subsection for each platform

Package installation instructions can likely remain as a separate, top-level section since that would bypass steps to download code and compile.
