 A one-of-a-kind command line 3D software rasterizer made with termion, tobj, and nalgebra. Currently it 
 supports OBJ file formats without textures or materials. Here's a really simple command for you to get started.    
-`cargo build --release`    
-`./target/release/sloth -r "0 0 90" hand.obj`    
+`cargo run --release -- models/hand.obj`    
 For multiple models:   
-`./target/release/sloth -r "0 0 90" "suzy.obj hand.obj"`   
+`cargo run --release -- "models/suzy.obj models/hand.obj"`   
+You can also generate a static image:
+`cargo run --release -- image -w <width_in_pixels> -h <height_in_pixels> models/suzy.obj`
+You can also generate a portable Javascript render like this:
+`cargo run --release -- image -j <number_of_frames> -w <width_in_pixels> -h <height_in_pixels> models/suzy.obj`
