When added, a fox icon appears at the top right corner, click on the icon, read the hint, click on Accept.
当登录到MetaMask之后，你的账户对你访问的所有网站都是可见的，为了你的隐私，在使用完MetaMask之后最好退出登录。同时也提示读者，默认情况下MetaMask会登录到一个测试网络，要使用真实的以太网络，需要用户手动连接到以太坊的主网络，这里后面会给大家演示
When you log in to MetaMask, your account is visible to all the sites you visit. For your privacy, it is best to exit after use of MetaMask. The reader is also advised that, by default, MetaMask will log into a testing network using the real Ether network, which requires a manual connection to Ether's main network, which will show you later.
5.点击“Accept”按钮，显示的是MetaMask的服务条款，默认情况下Accept按钮是灰色的，不要着急，点击右上角蓝色方框标出的下拉条拉到最下在， 按钮就可用了。点击“Accept”按钮，进入钱包登录页面。
Click on the " Accept " button to display the service terms of MetaMask. By default, the Accept button is gray. Don't worry. Click on the bottom drop marked in the top right corner blue box to the bottom, and the button is available. Click on the "Acccept" button to enter the wallet on the page.
6.这里用户有两种选择，一种是创建一个新的DEN（DEN是在MetaMask用密码加密存储的钱包），另一种是导入已经存在的DEN。这里先以创建为例，在上面的两个密码输入框中输入一密码，自己保存好输入的密码，点击“CREATE”图标，就创建了一个MetaMask钱包
The user here has two options: to create a new DEN (DEN is a wallet stored encoded by MetaMask) and to import DEN, which already exists. For example, enter a password in the two password input boxes above, save the password that you entered yourself, click on the "CREATE" icon and create a MetaMask wallet.
7.MetaMask会为用户创建12个英文助记词，一定要保存好这些助记词，一定要保存好这些助记词，一定要保存好这些助记词，在其他钱包导入这个新创建的账户的时候有可能需要这些助记词。
7. MetaMask will create 12 English assistive notes for users, which must be preserved, which must be preserved, and which may be needed when other wallets are imported into the newly created account.
8.保存好这些助记词之后，点击I’VE COPIED IT SOMEWHERE SAFE，进入钱包页面
After saving these notes, click on I'VE COPIED IT SOMEWERE SAFE to enter the wallet page
9.MetaMask已经自动为用户创建了一个钱包地址，地址“看不全”？没关系，点击右面的三个圆点，可以打开一个钱包地址相关的菜单
MetaMask has automatically created a wallet address for users, the address is "not all"? It's okay. Click three dots on the right to open a wallet address-related menu.
10.菜单中有4项，第一项是在Etherscan上查看该钱包地址的所有转帐信息，关于Etherscan使用后面会介绍。第二项是显示钱包的二维码，第三项是将钱包地址拷贝到粘贴板，第四项是导出钱包的私钥。其中第四项在导出私钥时会提示用户输入密码。
10. There are four items in the menu, the first of which is to view all the transfer information on the wallet address on Ethercan, and the second is to display the two-dimensional code of the wallet, the third is to copy the wallet address to the paster, and the fourth is to export the wallet's private key. The fourth of these is to alert the user to enter the password when exporting the private key.
这里的输入框就是输入在创建钱包时输入的密码，之后点击“Submit”
The input box here is the password entered at the time the wallet was created, and then click "Submit"
点击Save as File，把秘钥保存好，用户一定将其保存好，不要丢失，不要告诉别人，用户一定将其保存好，不要丢失，不要告诉别人，用户一定将其保存好，不要丢失，不要告诉别人。之后点击“Done”返回到钱包页面。
Click on Save as File, save the key, the user must save it, don't lose it, don't tell anyone, the user must save it, don't lose it, the user must save it, don't lose it, don't tell anyone. Click on Done to return to the wallet page.
11.点击钱包首页左上角绿色的“Main Network”
Click "Main Network" on the top left corner of the wallet
应该还记得上面介绍时提到，MetaMask提示读者其默认情况下是连接到测试网络，但通过上图我们可以看到，它现在的版本目前已经连接到主网络了，不需要对这里修改。
It should be recalled that, as mentioned in the introduction above, MetaMask suggests to the reader that its default is to connect to the testing network, but as can be seen from the chart above, its current version is now connected to the main network and there is no need to modify it here.
12.点击钱包右上角三条横杠的设置图标，显示设置菜单。这里有三个选项，第一个是“Setting”，这里可以设置钱包中虚拟币的计价方式，点击蓝色方框标出的下拉菜单可以选择计价方式，包括法币和虚拟货币，用户可以根据自己的习惯选择
Click on the setup icon of the three bars on the upper right corner of the wallet to display the setup menu. There are three options here, the first being Setting, where you can set a price for the virtual currency in the wallet, and click on the blue box-marked drop-down menu to select the price, including French and virtual currency, which users can choose according to their own habits.
第二个选项是“Lock”，当用户暂时离开电脑旁边时可以点击这一项，将钱包暂时锁定，需要输入登录密码才可以重新解锁
The second option is Lock, which can be clicked on when the user leaves the computer temporarily, locks the wallet temporarily and requires a login password to unlock it again.
二、MetaMask的主要功能
II. Main functions of MetaMask
前文介绍了MetaMask钱包的一些常用设置，这一节介绍MateMask作为钱包的主要功能。
Some of the usual settings for MetaMask wallets are described above, and the section describes Mate Mask as the main function of the wallet.
1 购买Eth
1 Purchase of Eth
点击钱包头面的“Buy”按钮，进入购买Eth页面。
Click the " Buy " button on the header of the wallet to get into the Eth page.
从这个页面可以看到，MetaMask支持两种购买Eth的方式，一种是从Coinbase购买，一种是通过ShapeShift。
As can be seen from this page, MetaMask supports two ways of purchasing Eth, one from Coinbase and the other through ShapeShift.
Coinbase是美国第一家持有正规牌照的比特币交易所，可以用美元购买比特币，但是目前明确不对中国人开放，所以本文先不介绍。
Coinbase, the first United States-owned duly licensed Bitcoin exchange to purchase bitcoin in United States dollars, is clearly not open to Chinese at this time and is therefore not presented here.
ShapeShift是一个无需帐户的数字货币兑换平台，可以将你自己的虚拟货币直接兑换为Eth。
ShapeShift is a digital currency exchange platform that does not require an account to convert your own virtual currency directly to Eth.
2 发送Eth
2 Send Eth
点击钱包首页的“Send”按钮，进入发送Eth的页面，填写要发送到的目的Eth地址、发送的Eth数量，点击“NEXT”即可
Click on the "Send" button on the front page of the wallet, enter the page to send Eth, fill in the number of Eths to send to, and click on "NEXT"
三、账户管理
III. ACCOUNTABILITY MANAGEMENT
所谓的账户管理，其实就是对Eth地址的管理。除了默认生成的一个地址，我们还可以创建新的账户或者导入已经存在的账户。点击钱包右上角右数第二个图标，第一项是目前存在的账户，第二项是“创建新账户”，第三项是“导入已经存在的账户”。
The so-called account management is actually the management of the Eth address. In addition to the default creation of an address, we can create a new account or import an account that already exists. Click the second icon on the right number of the upper right corner of the wallet, the first being an account that currently exists, the second being “Creating a new account” and the third being “Importing an account that already exists”.
3.1创建新账户
3.1 Create a new account
点击第二行的“Create Account”，新的账户就创建了，点击不同的账户，钱包会切换到对应的账户
Click on "Create Account" in the second line. New accounts are created. Click on different accounts, wallets are switched to the corresponding accounts.
3.2 导入账户
3.2 Import accounts
点击“Import Account”就可以导入其他账户，如其他钱包的地址，可以选择通过“私钥”方式（默认方式）导入，在第二个输入框中输入私钥，点击“IMPORT”即可
Click "Import Account" to import other accounts, such as the address of other wallets, to choose to import by "private key" (default), enter a private key in the second input box, and click on "IMPORT"
