 ## How to run
 From the command line, specify which mesh file (stored in ```/data/```) should be opened. For example with ```beetle.obj```  simply run
 ```
-build/shrink-morph beetle
+build/shrink_morph beetle
 ```
-To use the togcode script:
+For those who prefer to use a command-line version of a the app, use the ```shrink_morph_cli``` executable:
+```
+build/shrink_morph_cli mesh wD width nFmin
+```
+with ```mesh``` the name of the input mesh, ```wD``` the smoothing factor (0 by default), ```width``` the width of the flattened plate in mm, and ```nFmin``` the minimum number of faces in the input mesh (it gets iteratively subdivided until reaching this value). For example, to generate the same results as the ```hat``` model in the paper, type:
+```
+build/shrink_morph_cli hat 0.1 100 10000
+```
+
+To generate the final gcode files, use the togcode.py script. Its inputs are the .path file generated by the app, the name of your printer (only a few a supported at moment), and optionally the name of the output file, here is an example:
 ```
 python togcode.py ../data/input_file.path Creality_K1_Max -o output_file.gcode
+```
+
+## Display layers with Matplotlib
+To generate SVG files showing the trajectories similar to Figure 7 in the paper, runthe ```plot-layer.py``` script:
+```
+cd ../data/
+python plot-layer.py 1
+python plot-layer.py 10
