 Test cases
 ----------
 
-All test cases are kept short with a very reduced number of timesteps.  
+All test cases are kept short with a very reduced number of timesteps. Also the 
+setups itself are chosen with regard to small mesh size.
 IO is (mostly) switched off, only checksums are compared, netcdf or XML support
 is not needed. 
 However, each directory contains a namelist that can be adjusted for more
 realistic setups: increase the number of timesteps, switch on IO.
 
-* bm1_sloping_beach
+* **bm1_sloping_beach**
   Synthetic benchmark for the runup on a plain beach

-* bm2_okushiri
+* **bm2_okushiri**
   Channel experiment simulating the 1983 tsunami that heavily struck the Monai Valley on the Japanese island of Okushiri.

-* global_cosinebell
+* **global_cosinebell**
   A very coarse global mesh (far too coarse for realistic simulations!), 
   initialized with a cosine bell at the approximate location of the Lissabon 1755 earthquake and tsunami,
   though with increased magnitude of 9.0.
-* global_cosinebell_restart
+* **global_cosinebell_restart**
   As above, but the simulation is split half way and restarted once, to test this functionality.
 
+Adding test cases
+-----------------
+
+Basically, just add a directory with a namelist.tsunami, with write_final_checksums=.true. switched on.
+The script test_tsunawi.sh will automatically enter this directory and run TsunAWI.
