 NEUT has two dependencies: ROOT and CERNLIB. You need to have `$ROOTSYS`, `$CERN` and `$CERN_LEVEL` environment variables set-up to compile NEUT. These should all be specified by the user in `$NEUT_ROOT/src/neutsmpl/EnvMakeneutsmpl.csh`. 
 
-Compilation is done by running `./Makeneutsmpl` in `$NEUT_ROOT/src/neutsmpl/`: this sources the above `EnvMakeneutsmpl.csh`, runs through a host of makefiles, sets up symlinks and builds the project.
+`$ROOTSYS` should be set to your ROOT installation (e.g. sourcing `YOUR_DIR/root/bin/thisroot.sh`). `$CERNLIB` is your CERNLIB installation folder. `$CERN_LEVEL` is the folder inside `$CERNLIB` which you've installed: in my case (2017) the folder is called `2005`, so I set `export CERN_LEVEL=2005`.

 The `EVCT-MPV 3` says the flux is coming from a file, `EVCT-FILENM` specifies the file location of the flux, `EVCT-HISTNM` is the name of the TH1D inside `EVCT-FILENM`, and `EVCT-INMEV` specifies if the input histogram is in MeV or not.

+Once you have a working NEUT installation and generated events, you can link NUISANCE against NEUT.

+To run NUISANCE with NEUT you'll need to specify the `$NEUT_ROOT`, `$CERNLIB` and `$CERN_LEVEL` variables. 
+
+When building, set the environment variables and specify `-DUSE_NEUT=1` when generating the makefiles with `cmake`. Do:
+

+cd YOUR_NUISANCE_PATH
+mkdir -pv build
+cd build
+cmake ../ -DUSE_NEUT=1
+source $uname/setup.sh
+make
+make install
+make docs

+
+For multiple generator support (e.g. NEUT and GENIE enabled), simply set the environment variables for the generators, and compile with
+
+{{{
+cmake ../ -DUSE_NEUT=1 -DUSE_GENIE=1
+}}}
+
+instead.
