     * This processes the raw image `example-tulip-small/raw_tulip-small.bin`. Note that raw images are different from bitmaps, so you might need to obtain them using special software.
     * This generates: `tulip-small.bin` and `tulip-small-<stage>.bin` where `<stage>` represents the stage of the pipeline, in the directory `example-tulip-small`.
 3. Convert the binary outputs to a PNG with `./convert.sh example-tulip-small`.
+    * The convert script uses some scripts in the `script` directory. These need to be compiled first using `cd ./scripts; make`.
+    * **In order to compile the convert scripts, the path to numpy should be set correctly in the makefile.**
 4. View the resulting PNG at `example-tulip-small/tulip-small.png`. (As well as all the intermediary images for each stage `tulip-small-<stage>.png`).
