+# jcli Document
+
+`jcli` was written by [golang](https://github.com/golang) which could provide you a easy way to manage your Jenkins. Unlike the [build-in cli](https://jenkins.io/doc/book/managing/cli/), `jcli` allows you manage multiple servers.
+
+## How to get it
+
+Read [here](../README.md) to get know about how to install `jcli`.
+
+## Configuration
+
+Once you'v installed `jcli`. You should provide a config file for it. Please execute cmd `jcli config generate`, this will help you to edit the config file `~/.jenkins-cli.yaml`. According to your Jenkins configuration to modify this file.
+
+If you want to modify your config file of `jcli`. You just need to execute `jcli config edit`.
+
+It's simple to add another Jenkins config item. Here's a sample cmd: `jcli config add -n yourJenkinsName --url http://localhost:8080/jenkins --token replacethesampletoken`.
+
+## Plugin Management
+
+`jcli` allows you to search, download, install, uninstall or upload a plugin.
+
+First, please search a plugin by a keyword if you want to install it. You can get a plugin list by execute `jcli plugin search zh-cn`. You can install it with the plugin name.
+
+For example, you can install the Simplified Chinese Localization plugin by `jcli plugin install localization-zh-cn`.
+
+### Download Plugins
+
+Some times, Jenkins just cannot connect with the offical Update Center. We can use the `download` sub-cmd to download all the plugins which're you need, then upload them. This command will take care of the dependencies of the plugin.
+
+You can try it:
+
+`jcli plugin download localization-zh-cn`
