+Github 地址 : [SpaceVim/SpaceVim](https://github.com/SpaceVim/SpaceVim), 欢迎Star或fork，感谢支持! 使用过程中遇到问题在github提交issue将更容易被关注和修复。我们也欢迎喜欢vim的用户加入我们的QQ群，一起讨论vim相关的技巧，[点击加入Vim/SpaceVim用户群](https://jq.qq.com/?_wv=1027&k=43zWPlT)。
+
+SpaceVim 是一个模块化配置集合，包含针对各种语言开发的插件和相应的优化配置。目前支持多种语言的自动补全、语法检测、代码格式化，而且启动速度飞快。SpaceVim的另一核心理念就是按序延迟加载，目前90%的插件都是滞后加载。SpaceVim模块化的思想来源于 spacemacs的layer（模块），将各种功能包装好封装成一个layer，用户根据自己的需要载入相应的layer，实现自定义SpaceVim。
+
+SpaceVim对于新手有着非常友好的界面，界面格局和大多数IDE也比较类似。不过为了更好的体验SpaceVim，建议对于vim需要有一定的了解，如果有一定的英语基础建议阅读这篇关于vim的教程 vim-galore. 
+
+### 安装
+
+#### Linux 或 Mac 下 SpaceVim的安装非常简单，只需要执行以下命令即可：
+```sh
+curl -sLf https://spacevim.org/install.sh | bash
+```
+想要获取更多的自定义的安装方式，请参考：
+```sh
+curl -sLf https://spacevim.org/install.sh | bash -s -- -h
+```
+在初次使用SpaceVim的时候，当你打开vim时，SpaceVim会下载需要的插件，请等待下载过程完成，如果有失败的，可以手动执行 ：
+```viml
+:call dein#install()
+```
+SpaceVim是一种模块化配置，可以运行在vim或者neovim上，关于vim以及neovim的安装，请参考以下链接：
+
+[安装neovim](https://github.com/neovim/neovim/wiki/Installing-Neovim)
+
+[从源码编译vim](https://github.com/Valloric/YouCompleteMe/wiki/Building-Vim-from-source)
+
+#### windows系统下的安装步骤：
+
+Windows 下 vim 用户只需要将本仓库克隆到用户 HOME 目录下的 vimfiles 即可，打开 CMD 默认的目录默认即为 HOME 目录，只需要执行如下命令即可：
+```sh
+git clone https://github.com/SpaceVim/SpaceVim.git vimfiles
+```
+Windows 下 neovim 用户 需要将本仓库克隆到用户 HOME 目录下的 AppData\Local\nvim，想要获取跟多关于 neovim 安装相关的知识，可以访问 neovim 的 wiki， wiki 写的非常详细。打开 CMD 初始目录默认一般即为 HOME 目录，只需要执行如下命令即可：
+```sh
+git clone https://github.com/SpaceVim/SpaceVim.git AppData\Local\nvim
+```
+### 特性
+
+以neovim为主的新特性实现
+模块化设置
+依赖 dein.vim 的延迟加载，90%插件延迟加载，启动速度极快
+高效，轻量级
+Unite为主的工作平台
+优雅的界面
+针对不同语言开发的优化
+可扩展的补全引擎，vim下为neocomplete， neovim 下为 deoplete
+细致的tags管理
+轻量级状态栏
+优雅的主题
+
+### 文件结构
+
+- [config](./config)/ - Configuration
+  - [plugins](./config/plugins)/ - Plugin configurations
+  - [mappings.vim](./config/mappings.vim) - Key mappings

+- [vimrc](./vimrc) - Sources `config/main.vim`
+
+### 模块化设置
+
+1. SpaceVim 将从 ~/.local.vim 和当前目录的 .local.vim 载入用户配置，（该方式将被舍弃）.
+2. SpaceVim 将从 ~/.SpaceVim.d/init.vim 和当前目录的 ./SpaceVim.d/init.vim 载入配置，并且更新 rtp，用户可以在 ~/.SpaceVim.d/ 和 .SpaceVim.d/ 这两个文件夹下编辑自己的脚本，和 SpaceVim 的配置文件。
+
+示例：
+
+```viml
+" here are some basic customizations, please refer to the top of the vimrc file for all possible options
+let g:spacevim_default_indent = 3
+let g:spacevim_max_column     = 80
+let g:spacevim_colorscheme    = 'my_awesome_colorscheme'
+let g:spacevim_plugin_manager = 'dein'  " neobundle or dein or vim-plug
+
+" change the default directory where all miscellaneous persistent files go
+let g:spacevim_cache_dir = "/some/place/else"
+
+" by default, language specific plugins are not loaded.  this can be changed with the following:
+let g:spacevim_plugin_groups_exclude = ['ruby', 'python']
+
+" if there are groups you want always loaded, you can use this:
+let g:spacevim_plugin_groups_include = ['go']
+
+" alternatively, you can set this variable to load exactly what you want
+let g:spacevim_plugin_groups = ['core', 'web']
+
+" recommend to use layer function, all the layers's name can be find in `:h SpaceVim-layers`
+call SpaceVim#layers#load('layer_name')
+
+" if there is a particular plugin you don't like, you can define this variable to disable them entirely
+let g:spacevim_disabled_plugins=['vim-foo', 'vim-bar']
+
+" if you want to add some custom plugins, use this options.
+let g:spacevim_custom_plugins = [
+        \ ['plasticboy/vim-markdown', 'on_ft' : 'markdown'],
+        \ ['wsdjeg/GitHub.vim'],
+        \ ]
+
+" anything defined here are simply overrides
+set backgroud=light
+set nu
+
+" but some options need to use spacevim's option, such as:
+let g:spacevim_guifont = 'DejaVu\ Sans\ Mono\ for\ Powerline\ 11'
+```
+
+#### Unite 为主的工作流
+1. 列出所有插件，并且可以根据输入的字符模糊匹配，回车将打开对应插件的github网站， 这非常便于临时去github上面找文档，默认的启动快捷键是 ： `<leader>lp`
