To get the krem_plugins version compatible with the latest KREM, please clone the default branch stable.
Always clone a branch which is named after the KREM version you are using. For instance, if your KREM version is tagged v2.3.0_stable, then clone krem_plugins from branch krem_v2.3.x_compatible.
We recommend to clone directly into <your_krem\ project>/library/plugins
Copy the file krem_plugins/setup.py into <your\ krem\ project>/library and uncomment the plugins you want to use
See <krem installation>/docs/KREM_USER_MANUAL.md for guide to setup plugins in your project.
