Ethereum - smart contracts run on top of Ethereum Virtual Machine. Each state change is “saved” to the blockchain, but not to the memory of the single computer.
Very good list of Blockchain resources is available here (but don’t stop to read this document!) -
**Very good book that is must read for any blockchain developer. Currently Ethereum uses same crypto-consensus algorithm, just like Bitcoin does. There is no necessity to read the whole book, you can skip chapters and sections.

export the wallet to JSON
load the JSON
send or receive test transaction (say, 0.00000001 ETH)
Create coinbase account -very easy way to keep you crypto (but please don’t keep a lot! you can loose your money, because the service is centralized; also it can be hacked).
check your transactions
switch between mainnet and testnet
install geth and start it from your console
install parity and start it from your console (kovan or rinkeby testnet) + connect from the browser
Install Mist (Ethereum Wallet) and start syncing it with the mainnet (can take more than 100+ GB on your hdd)
create new account
check how smart contract deployment works
