+  The <code>go</code> command now supports a "Workspace" mode. If a
+  <code>go.work</code> file is found in the working directory or a
+  parent directory, or one is specified using the <code>-workfile</code>
+  flag, it will put the <code>go</code> command into workspace mode.
+  In workspace mode, the <code>go.work</code> file will be used to
+  determine the set of main modules used as the roots for module
+  resolution, instead of using the normally-found <code>go.mod</code>
+  file to specify the single main module.
