 If you don't want to use CommModelPy as PyPI module, you can also download this repository directly. The main script file is the commmodelpy.py Python script in the "commmodelpy" subfolder.
 
+### Optional external package: eQuilibrator API
+If you want to run the reaction dG0 calulations performed in the course of CommModelPy's publication results (see next chapter), you also have to install the [eQuilibrator API](https://gitlab.com/equilibrator/equilibrator-api) (not affiliated with CommModelPy or its developers) which is not included here due to its large download size of >1GB. You can download the API as follows from PyPI:
+
+<pre>
+pip install equilibrator-api
+</pre>

 ## Repository structure
 
 * The actual commmodelpy pip package can be found in the "commmodelpy" subfolder, where "commmodelpy.py" contains all relevant functions and dataclasses.
-* All Python scripts which were used in CommModelPy's publication, which use CommModelPy's function for community models without defined growth and with fixed species ratios, can be found in the "publication_runs" subfolder, which is in the "commmodelpy" subfolder. The scripts in the local subfolder "toy_model" contain the script for the generation of the toy model shown in the publication. The scripts in the local subfolder "ecoli_models" contain the generation of dG0 data using the [Equilibrator API](https://gitlab.com/equilibrator/equilibrator-api) as well as the CommModelPy-assisted generation of iML1515 and EcoliCore2 single-species community models. A complete call of all E. coli model scripts in the right order is given by the "execute_publication_ecoli_model_scripts.py" script in the main folder, a call of the toy model scripts is given by the "execute_publication_toy_model_script.py" script in the main folder.

 * An exemplary usage of CommModelPy with its function with a defined fixed growth rate and free species ratios can be found in the "balanced_growth_example" subfolder. A call of the relevant script is given in the "execute_balanced_growth_example.py" script in the main folder.
