+### Ignoring directories
+
+Out of the box, NuPU ignores a list of directories to process like `bin`, `.git`, `packages`, and similar. You can override this behavior by creating a file named `.nupuignore` in a root folder you want to run the NuPU command in:
+
+```
+.git
+.github
+.vs
+.vscode
+bin
+obj
+packages
+node_modules
+my_custom_folder
 ```
