If you also want to contribute to the code base, you may want to join the Open source community. All the information (membership, procedures, roles, etc)…is described here: https://www.fiware.org/fiware-community/ If you have any difficulties with the open source community, we can direct you directly to someone involved in this new open source community initiative. Hope this helps for now. Kind regards, ilknur
