In order to build from sources and use LoMRF, either as a program or as a programming library, you need to follow the build and link instructions.
If you are interested in learning LoMRF by using examples or contribute, we suggest to get the LoMRF-data sub-module. The LoMRF-data contains examples (see, for instance, Inference) as well as sample files that are used by Unit testing.
