 There are two recommended ways of running the project:
 
-1. Building and running the docker file:
+Option number `1` has the advantage of running within Docker, where everything
+is fired up automatically, including certificates generation, tests and linting.
+
+Also both SECC and EVCC are spawned, automatically.
+
+For option number `2`, the certificates need to be provided. The project includes
+a script to help on the generation of -2 and -20 certificates. This script
+is located under `iso15118/shared/pki/` directory and is called `create_certs.sh`.
+The following command provides a helper for the script usage:
+
+```bash
+$ ./create_certs.sh -h
+```
+
+Use the following commands to generate certificates for 15118-2 and 15118-20:
+```bash
+$ ./create_certs.sh -v iso-2
+$ ./create_certs.sh -v iso-20
+```
+
+Option 1. Building and running the docker file:
 
    ```bash
    $ make build
    $ make dev

    Install JRE engine with the following command:
 
    ```bash
    sudo apt update && sudo apt install -y default-jre
-
    ```
 
-   The JRE engine is only a temporary requirement until we replace the Java-based
-   EXI codec (EXIficient)[^4] with our own Rust-based EXI codec.
-
-   Install the module using `poetry` and run the main script related
-   to the EVCC or SECC instance you want to run. Switch to the iso15118 directory
-   and run:
-
-   ```bash
-   $ poetry update
-   $ poetry install
-   $ python iso15118/secc/start_secc.py # or python iso15118/evcc/start_evcc.py
-   ```
+   The JRE engine is only a requirement in Josev Community if using the Java-based
+   EXI codec (EXIficient)[^4]. Josev Professional uses our own Rust-based EXI codec.
 
-   For convenience, the Makefile, present in the project, helps you to run these
-   steps. Thus, in the terminal run:
