Display the recently viewed items

Hi,
This is something that I should have figured out ages ago but but didn't need to:
How do I display the recently viewed items on the bottom of the page.
Please give instructions as if you were speaking to someone clueless. (because you are)

Thanks

steve

Here is what I don't understand:
I make a Hikashop module and enable it in a specific module position, on the home page only, using the Joomla module manager. Hikashop seems to overide the Joomla module manager and place the module on every page. Or failing that, on any pages that its settings determine. I can't seem to understand how Hikashop decides on what pages to place the module. Please can you help me understand this.
Thanks

Ok here is the situation.

I can now have select items show up in a module position on a specified page which is great but when I select one of the items in the module position and go to the product page, the module stays where it is.
In other words, if the module is listed on the home page it will show, only on the home page BUT if a product it selected and then the product page comes up, the module position is still there.

Also, on the recently viewed items thing: I tried creating a new module from the configuration page as per the instructions and I've tried creating it from the Joomla module manager, in each case, Hikashop will show items but I cannot figure out how to set the settings in order to get it to show recently viewed items.
Thanks

Ok I've got the " recently viewed items" where I need it and there are items being shown in it. But here is the thing: some items show in it and some don't. And some seem to stay in the "recently viewed" when I would expect them to be cycled out. What controls the selection and behavior of the items?

Thanks Nicolas, I really appreciate your help

hi Nicolas, finally im stuck with something in HikaShop - cant figure out what options exactly should i set for module to display list of recently viewed items. now it displays some items but they seem unrelated to current session.
joomla 2.5.1 / hikashop 1.5.6 Starter

i kinda have russian language override

sorry for that, took some time to replace ini back.

didnt help, just showing static list of some prods no matter what i do.

now it seem to work, but all main product images are replaced by default pic and recent items are shown in reverse order.

The issue I have is that I want just a few of the most recent showing, e.g. the 3 most recently viewed by the current user. The recently viewed seems to be across the whole site site, so what is viewed by other visitors also counts. I would like the behaviour to be like Amazon, where you see that latest products YOU have viewed. Is this possible?
