+space-vim aspires to adhere to the zero-install philosophy, just clone and use. Optional dependencies not installed on the system are downloaded and built from source where possible, and are used embedded within the application.

-## Customize
-
-You can use `.spacevim` in your home directory to customize space-vim, where you can enable the existing layers, add your extra plugins and private configurations.
 
-If `.spacevim` does not exist, vanilla vim will be loaded! Refer to [init.spacevim](init.spacevim) as an example.
 
-### Presetting
 
-```vim
-" Comment the following line if you don't want Vim and NeoVim to share the
-" same plugin download directory.
-let g:spacevim_plug_home = '~/.vim/plugged'
-
-" Uncomment the following line to override the leader key. The default value is space key "<\Space>".
-" let g:spacevim_leader = "<\Space>"
-
-" Uncomment the following line to override the local leader key. The default value is comma ','.
-" let g:spacevim_localleader = ','
+## Customize
 
-" Enable the existing layers in space-vim
-" Refer to https://github.com/liuchengxu/space-vim/blob/master/layers/LAYERS.md for all available layers.

-" endif

+### .spacevim details
 
 Please refer to [LAYERS.md](layers/LAYERS.md) to take a look at the whole shipped layers.
 
 Basically, `g:spacevim_layers` almost takes the place of `Layer` command. As far as I known, most people never use the option of `Layer` command, e.g., `exclude`, so `g:spacevim_layers` could save a lengthy `Layer` list, requiring less ceremony. Nevertheless, `Layer` command is still avaiable for some advanced uses.
 
 ### `UserInit()`
 
+`UserInit()` may be used to add plugins that are not within a layer.

 ```vim

 ### `UserConfig()`
 
+Configuration may be placed in `UserConfig()`, and/or in a `plugin/` folder on the runtime path. E.g. `~/.vim/plugin/<pluginname>.vim` for each local plugin configuration.

-Alternatively, you can manually perform the following steps. If anything has changed with the structure of the configuration, you will have to create the appropriate symlinks.
