 To build your application, you need to specify where your source code is via the `path` argument, this defaults to `src`.
 
 The source code directory should have your `.spec` file that PyInstaller generates. If you don't have one, you'll need to run PyInstaller once locally to generate it.
+Also if you have another program `.spec` file you can set specific pyinstaller `.spec` file by `spec: <YOUR_SPEC_FILE_NAME>`
 
 If the `src` folder has a `requirements.txt` file, the packages will be installed into the environment before PyInstaller runs.
