 ## Compiling:
-in fish:
+
-```fish
+```bash
 # load requirements
 nix-shell --run fish
 # run gcc with flags
-gcc (pkg-config --cflags --libs gtk+-3.0 | string split " ") -lm -Wall -Wextra -o march.out main.c
+gcc -lm -Wall -Wextra -o march.out main.c
 ```
 
 ## Running
 
 give it the number of threads you want to use
 ```bash
-./march.out <num threads>
+./march.out <power> <file name>
 ```
+
+## Animating the power
+
+Make sure you compiled a version of the program wich takes the power as first arg and target file name as second arg. I would suggest you hardcode the number of threads to use and set up a suitable camera location manually.
+
+Then edit the parameters in the animate script (it's a fish script, just beware of that) and run it. Depending on your parameters this might take a loooong time to complete. The animate script will not show output of each individual render, but instread display a little progress meter showing the percent of frames complete, the starting power, current power, and the power we want to reach.
