+### Explorer File Nesting Defaults
+
+The extension contributes file nesting patterns so common VB artifacts are grouped in the
+Explorer (for example, `.Designer.vb`, `.g.vb`, `.g.i.vb`, `.generated.vb`, `.AssemblyInfo.vb`,
+and `My*.vb` under their primary `.vb` file). You can override these defaults via
+`explorer.fileNesting.patterns` in your settings.
