+## Building Plugins
 
-1. Build [nomacs](https://github.com/nomacs/nomacs)
-2. Open CMake GUI
-3. set the plugin repository's root folder containing CMakeLists.txt to `where is the source code`
-4. choose a build folder
-5. Set OpenCV_DIR, QT_MAKE_EXECUTABLE, and nomacs_DIR
-    - Copy `CMakeUserPathsGit.cmake` and rename it to `CMakeUserPaths.cmake`
-    - Set all paths to your own builds of nomacs etc.
-6. Hit `Configure` then `Generate`
-7. You will find a nomacs-plugins.sln which builds all plugins and dedicated plugin projects in the respective folders (e.g. PaintPlugin/paintPlugin.sln)
-8. Tip: Go to Plugin > Properties > Configuration Properties > Debugging and set the Command to your nomacs path (e.g. C:/nomacs/build2015-x64/Debug/nomacs.exe) to better debug your plugin
+- Clone [nomacs](https://github.com/nomacs/nomacs.git)
+- cd to the repository, then:
+```bash
+git submodule init
+git submodule update

-## Build Plugins (Ubuntu)
 
-- Clone [nomacs](https://github.com/nomacs/nomacs.git)
-- cd to `nomacs/ImageLounge`
-- clone this [repository](https://github.com/nomacs/nomacs-plugins.git) into `plugins`:
-````terminal
-git clone https://github.com/nomacs/nomacs-plugins.git plugins
-````
-- in `ImageLounge` create a folder `build` and run cmake:
-````
-mkdir build
-cd build
-cmake -DENABLE_PLUGINS=ON ..
-````
-- then build the project:
-````terminal
-make
-````
-
-This will build all the Plugins set to 'ON' in nomacs-plugins/CMakeLists.txt. Running ./nomacs from the nomacs/ImageLounge directory should now list all the built Plugins in the Plugins tab.
+### Debug Plugins (Visual Studio)
