Link to access new and updated doc:https://gitlab.eurecom.fr/oai/openairinterface5g/blob/issue414_doc/doc/RUNMODEM.md https://gitlab.eurecom.fr/oai/openairinterface5g/blob/issue414_doc/doc/BUILD.md Switch to WIP state as it is only documentation , don't want CI to run each time some typo or other minor improvement is done
