The following is the command you would use in CMD Prompt to create a new module within odoo.
"C:\Program Files (x86)\Odoo 13.0\python\python.exe" "C:\Program Files (x86)\Odoo 13.0\server\odoo-bin" scaffold MODULE_NAME_HERE "C:\Users\Equity & Help\PycharmProjects\matrix-staging"
Below I will explain in bold what each section means.
"C:\Program Files (x86)\Odoo 13.0\python\python.exe" This is locating where the python.exe is on your computer "C:\Program Files (x86)\Odoo 13.0\server\odoo-bin" This is locating where odoo-bin is on your computer scaffold MODULE_NAME_HERE MODULE_NAME_HERE you will replace whatever you want to name your new module here "C:\Users\Equity & Help\PycharmProjects\matrix-staging" This is the folder that the module will be created in. Change this to be the directory to where you want the folder to output.
Once you have changed the above accordingly, press enter and it will create the folder where you set it to output. It will have a template setup for you to start creating your new Odoo module.
