### In NEO, public key and public address are two different things. 
If you wanna be an NEO developer, you need your NEO public key to apply testNet NEO&GAS, and it's kind of tricky to get your own public key. You cannot get it from a Neon Wallet, you need to use Neo CLI(command line interface). Today I'm here to show you how to create a new wallet and get your public key using NEO-CLI in Linux Ubuntu 16.04.
>這陣子想要試試看在NEO上面的應用開發，所以要申請一下TestNet上面的NEO還有GAS。殊不知申請的步驟裡要輸入Public Key，而不是Public Address，搞的我一個頭兩個大。好不容易搞懂要用NEO的CLI(command line interface)才能看到自己的公鑰，只好親手來試試囉

It's actually very easy, all you have to do is download neo-cli, compile it and run some simple commands.

> 其實CLI真的沒有想像中可怕，但是看到黑底白字就會覺得好像要很專業才有辦法使用。其實整個過程也就只是安裝些套件，然後下點簡單指令罷了。所以我就紀錄一下在Ubuntu 16.04環境下如何創立新的錢包，並且讀取自己的Public Key吧！

### 1. install pre-requirements
`sudo apt-get install libleveldb-dev sqlite3 libsqlite3-dev libunwind8-dev`

### 2. You may also need to install **dotnet core 2.0** for neo-cli to run(if you don't have it).
```
curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg
sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg
sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-ubuntu-xenial-prod xenial main" > /etc/apt/sources.list.d/dotnetdev.list'
```
Then, update the package cache and install .NET Core
```
sudo apt-get update
sudo apt-get install dotnet-sdk-2.0.0
```

### 3. Download and unzip latest NEO-CLI realease
https://github.com/neo-project/neo-cli/releases

### 4. Go into the folder, run:
`dotnet neo-cli.dll`
You should be able to run NEO CLI!

#### You can type in `help` and find some instructions about the commands
(And more detail [here](http://docs.neo.org/en-us/node/cli.html))

### 5. Now I want to create a new wallet, just type in `create wallet [path under neo-cli/]`. 
Remeber that the filename should be ended with `.json` or `.db3`

#### You have successfully created a new wallet! You can copy your public key here right now.

### 6. In the future, you need your password to open the wallet to see your keys again. To open your wallet:
`open wallet: [your wallet path]`

### With your wallet opened, you can now do a lot of stuff with the CLI! 

#### I'm just using the CLI to get my public key so I can get some NEO and GAS on testNet ;)

#### That's it! Happy Developing on NEO!
#### 謝謝大家，這一篇就這麼簡單的結束了xD一起來成為NEO的開發者吧！
