Is there a way for me to run the minifabric in dev-mode, if so what should I do?

I tried to apply the patterns used in the fabric, in this tutorial https://hyperledger-fabric.readthedocs.io/en/release-1.4/peer-chaincode-devmode.html but I can't do this process. Is there a way? I noticed that in the core.yaml file there is an attribute called mode: net which could be mode:dev but I believe that simply modifying it does not solve my problem.
