 ## Documentation
 
+### Quick start guide
+
+SpaceVim load custom configuration from `~/.SpaceVim.d/init.vim`, 
+
+:warning: It is not `~/.SpaceVim/init.vim`, user should not change anything in `~/.SpaceVim/`.
+
+here is an example:
+
+```vim
+" Here are some basic customizations, please refer to the ~/.SpaceVim.d/init.vim
+" file for all possible options:
+let g:spacevim_default_indent = 3
+let g:spacevim_max_column     = 80
+let g:spacevim_colorscheme = 'jellybeans'
+let g:spacevim_plugin_manager = 'dein'  " neobundle or dein or vim-plug
+
+" Change the default directory where all miscellaneous persistent files go.
+" By default it is ~/.cache/vimfiles.
+let g:spacevim_plugin_bundle_dir = '~/.cache/vimfiles'
+
+" By default, language specific plugins are not loaded. This can be changed
+" with the following, then the plugins for go development will be loaded.
+call SpaceVim#layers#load('lang#go')
+
+" loaded ui layer
+call SpaceVim#layers#load('ui')
+
+" Alternatively, you can set this variable to load exactly what you want:
+let g:spacevim_plugin_groups = ['core', 'web']
+
+" If there is a particular plugin you don't like, you can define this
+" variable to disable them entirely:
+let g:spacevim_disabled_plugins=[
+    \ ['junegunn/fzf.vim'],
+    \ ]
+
+" If you want to add some custom plugins, use these options:
+let g:spacevim_custom_plugins = [
+    \ ['plasticboy/vim-markdown', {'on_ft' : 'markdown'}],
+    \ ['wsdjeg/GitHub.vim'],
+    \ ]
+
+" set the guifont
+let g:spacevim_guifont = 'DejaVu\ Sans\ Mono\ for\ Powerline\ 11'
+
+" use space as `<Leader>`
+let mapleader = "\<space>"
+```
