 2. Run the container:
 ```docker run -it -v $(pwd):/code angio /bin/bash run.sh <run_id>```. Please make sure that an input file named ```inp<run_id>``` is present in the root directory of the project.
 
+### Parameters
+
+We provide typical parameters for simulations in [`input_file`](https://github.com/phydev/angio/blob/master/input_file). 
+
+Beware that the input file `inp001` is solely used to run the docker image with Github actions. The parameters were changed to produce a short simulation with small grid, few iterations, and no sources of VEGF. Please do __not__ base future studies on this file.
