-* Please write a longer instrument description here!
-* 
+* Model of the proposed ESS instrument KVASIR, implemented using McStasScript /
+* a Jupyter notebook. The flat ESS_KVASIR.instr runs from off an MCPL file from
+* a BIFROST guide guide simulation and adds the secondary spectrometer from
+* the proposed KVASIR instrument.
+*
+* %Example: t=50 Detector: det_He3_0_ToF_I=0.0302392
 * 
 * %Parameters
-* t: [unit] 
-* 
+* t:       [1] Number of simulated KVASIR 'wedges'
+* repeats: [1] Repeat count for MCPL input file
