Currency module step by step guide I want to provide a block where user can convert the currencies as desired and get the latest conversion rate.

I'm using Currency module. But there is no any set up guide for it, so I'm unable to use it. Can somebody tell me how to set it up?

If it is not possible in this module, is there any other module?
