Electrum is a light weight Bitcoin wallet. There are many advantages of using a Desktop wallet, as opposed to keeping your digital currency on an exchange, where you have less control. Another, and possibly safer solution, would be using a hardware wallet.
One of the big advantages of Electrum is that you don't have to download the entire blockchain, so you can start using it right away.
You can install Electrum by following the "Installation from Python sources" directions on https://electrum.org/#download
It's probably best to verify that it matches the signature file, by following the directions under "How to verify GPG signatures". Supposedly, the WARNING part of the message can be ignored. The important thing is the "Good signature...." message. The "not certified with a trusted signature..." message just means that you haven't used your own private key to sign the Mint key as trusted."
