1. Installation, create block chain ETH address account

2. To 0.1 ETH
3. Enter the website https://www.myetherwallet.com/for contract release
The first need to login first: click here to login to choose, choose MetaMask, and then select login



4. After logging in the diagram below: choose the arrow mark, click on the Contract first, and then click the Deploy Contract; Appear on the right way is, need to Byte Code and ABI, to write intelligent contract

Contract code as follows, do not do any modification:

Then began to compile after 6: code copy: click on the following figure





Select the corresponding version (I this is just a screenshot, you choose your own)


Click the compile: ABI in the lower left corner and the ByteCode; This in the previous screenshots useful to copy to summer orders, the corresponding position:


The number of tokens for HTUT, I am here for a number of $

And then submit, he will show you to continue to trade payment, is the fee for absenteeism, click on the top right corner will be a payment message, below


Click on the confirmation, after the success of the payment, and then he will automatically deploy contracts, wait a minute, to block the browser check your ETH Lord account things: address is: https://etherscan.io/address/(add your own pay the costs of miners ETH account address); Click to enter




Under the plan for your tokens, address, and then view the tokens of specific information: address is:
https://etherscan.io/token/(your own tokens, address)
