Install the library into your libraries folder. On my system it's at $HOME/Arduino/libraries, so the ModbusRtu.h file should be at $HOME/Arduino/libraries/ModbusRtu/ModBusRtu.h. If you have another operating system than me (I use Linux) you might have to change these Paths. Sketches usually are saved by the IDE to the same folder ($HOME/Arduino in my case).
Unfortunately the ModbusRtu library is not available in the Library Manager of the IDE.

Once you have copied the library files to that folder you have to restart the IDE, otherwise it won't notice.
