Using Ethereum Mist Wallet

Ethereum main wiki

Mist release
https://github.com/ethereum/mist/releases


Step-by-Step Guide: Getting Started with Ethereum Mist Wallet

https://medium.com/@attores/step-by-step-guide-getting-started-with-ethereum-mist-wallet-772a3cc99af4


Use testnet
https://testnet.etherscan.io/

Choose RINKEBY
https://rinkeby.etherscan.io/

Start geth testnet
geth --fast --cache=512 --rpcapi personal,db,eth,net,web3 --rpc --testnet




Start mist - without local testnet
