+### Non-project files
+By default, files that are not part of the project are added and analyzed as part of an anonymous library. You can disable this behaviour by changing the `vhdlls.nonProjectFiles` setting from `analyze` to `ignore`. Note that changing this setting requires a restart of the langauge server to become effective.

 ## Technology under the hood

 Pre-compiled binaries for Linux and Windows are provided with the extension.
