+Go
+==
+
+What is Go?
+-----------
+
+This Go is not the programming language from Google. This is a shell command which can help manage multiple remote servers SSH access easily, and do not need to remember so many accounts for those servers.
+
+OS requirements
+---------------
+
+The command tested on MacOSX, but should be working on most linux distributions. It depends on expect on your local system, and the remote servers need to enable SSH.
+
+If you feels something wrong, please [file an issue](https://github.com/vipzhicheng/go/issues/new) on this project, because I do not test the scripts on every case, but I am happy to help you out.
+
+Usage
+-----
+
+I am just showing the usage for MacOSX users, other OS usage maybe different, but the idea is same.
+
+### Check out code from Github
+
+```
+$ mkdir ~/bin
+$ cd ~/bin
+$ git clone https://github.com/vipzhicheng/go.git
+$ cd go
+$ cp .go.conf.example ~/.go.conf
+$ chmod a+x go
+$ chmod a+x ssh-expect
+```
+
+### Set PATH in .bash_profile
+
+```
+export PATH=~/bin/go:~/bin:$PATH
+```
+
+```
+$ source ~/.bash_profile
+```
+
+### Set ~/.go.conf, you can see demo settings as follows.
+
+```
+# IP USER:PASS LABEL
+
+192.168.1.7:22000 user1:pass1 label:7
+192.168.1.8 user2:pass2 label:8
+192.168.1.9 user3::absolute_private_file_path label:9
+```
+
+You can ignore port setting if you are using default port(22) in remote server.
+
+### How to use this command
+
+```
+$ go label
+
+Found follow servers: (Which one do you want to connect?)
+[1] [email protected] label:7
+[2] [email protected] label:8
+Please choose by ID:
+1
+
+Logging into [email protected] ...
+spawn ssh [email protected] -p 22000
+[email protected]'s password:
+Last login: Mon Mar 10 18:35:02 2014 from 192.168.1.6
+$
+```
+
+### Options
+
+There is only one option, -g, with this option, you can add -D7070 to the connection.
+
+### Change log
+
+2015-06-01
+1. Ignore comments lines
+2. Add support for secret file
+
+Inspiration & Thanks
+--------------------
+
+I know it must be somewhere about the situation of manage multiple SSH accesses via expect. Then I found [this](http://imbugs.com/blog/articles/99.html), which is written in Chinese. Thanks for the code, most of this project is from that code, but some features I need are missing. so I added them into this project.
