How to add currencies?

I just installed Tryton with Docker: How to run Tryton using Docker
Then I logged in via webbrowser and enabled company and countries module. But I could not create a company, because it wants a currency,
So I installed Currencies, log out, log in but no currencies at all. Also not a singe country is shown in module Countries.
Then I update modules, and make database update. Modules installed but without any content.

You can create yourself the currencies that you want to use.
Or you can load all the ISO currency following: Setup — Tryton module with currencies

Thank you, I thought it is included because of the description of the module: " The Currency Module defines the basics … including a list of standard currencies"
