 2. Build the library:
 
 ```bash
-cd user_ie_extensions
+cd openvino_contrib/modules/custom_operations
 mkdir build && cd build
-cmake .. -DCMAKE_BUILD_TYPE=Release && cmake --build . --parallel 4
+cmake ../user_ie_extensions -DCMAKE_BUILD_TYPE=Release && cmake --build . --parallel 4
 ```
 
 If you need to build only some operations specify them with the `-DCUSTOM_OPERATIONS` option:
 ```bash
-cmake .. -DCMAKE_BUILD_TYPE=Release -DCUSTOM_OPERATIONS="complex_mul;fft"
+cmake ../user_ie_extensions -DCMAKE_BUILD_TYPE=Release -DCUSTOM_OPERATIONS="complex_mul;fft"
 ```
 
 - Please note that [OpenCV](https://opencv.org/) installation is required to build an extension for the [fft](examples/fft) operation. Other extentions still can be built without OpenCV.
