 ### Dump Schematic to Standard Output
 
+This will print out mapping and each block as hex values layer by layer.
 ```
 ./mtsedit -d structure.mts
 ```
 
+### Generate blueprint
+
+Pretty much the same as dump, but instead of dumping the MTS to the console, it saves "structure_bp.png".
+```
+./mtsedit -b structure.mts
+```
+Each layer will be padded by 1 x 1 pixels of transparency. On the left, there's a black pixel after each layer so
+that programs can detect the dimensions from the image. On the right, there's a red line for the ground layer.
