 ## Features
 This extension allows you to view C++ Insights inside of vscode:
-<p align="center">
-  <br />
+<p>
   <img src="image/show.png" alt="Show C++ insights" />
 </p>
 
 or diff the Insights with your original source:
-<p align="center">
-  <br />
+<p>
   <img src="image/diff.png" alt="Diff source with C++ insights" />
 </p>
 
+The extension can utilize a compilation database/compile commands for easy use in existing environments. You can specify a directory containing the compilation database, aka the  build directory, with `vscode-cppinsights.buildDirectory`.
+If the active file is part of a workspace, and `vscode-cppinsights.buildDirectoryPrioritizeCMake` is set, the `cmake.buildDirecotry` is used to determine the build direcotry.
