A simplistic User Interface (Nostalgia), is provided to help community members get started with using IOTA. The actual GUI wallet will be released in a few days, so if you don't feel comfortable with Nostalgia, I suggest you to wait until the wallet is ready.
As a first step, you should download Nostalgia from our Github:
If you are on Linux/Mac, you can simply open your console and clone the project:
git clone https://github.com/domschiener/nostalgia
Else you can also simply download the zipped version from here: https://github.com/domschiener/nostalgia/archive/master.zip
Now in order to run nostalgia, all you need to do is open up
If you are using a different port than 14265, change line 18 in nostalgia.html to the correct port.
Now all you have to do is type in your seed and hit enter in order to login. You should now see an empty screen and you can start sending transactions and generating addresses.
If you have already made transactions, Nostalgia will mark sent transactions in red (as in the picture below), so that you know to which address you have sent tokens.
In addition to that, you can also take a look at the entire bundle by clicking on "Show Bundle". The transactions form the bundle will be marked in blue. If you click on Show Bundle again they will disappear.
