How can I add my own MISP module?

[Aledangelo]

I created a MISP module, I added it in the export_mod folder in /usr/local/src/misp-modules/misp-modules/modules/export_mod, and I insert its name in "all " variable in" init.py" file. Have I missed some steps? I can't find my module in the UI (Server Settings & Maintenace window)
