+## EditorConfig
+
+SpaceVim has support for [EditorConfig](http://editorconfig.org/), a configuration file to “define and maintain consistent coding styles between different editors and IDEs.”
+
+To customize your editorconfig experience, read the [editorconfig-vim package’s documentation](https://github.com/editorconfig/editorconfig-vim/blob/master/README.md).
+
+## Vim Server
+
+SpaceVim starts a server at launch. This server is killed whenever you close your Vim windows.
+
+### Connecting to the Vim server
+
+If you are using neovim, you need to install [neovim-remote](https://github.com/mhinz/neovim-remote), then add this to your bashrc.
+
+```
+export PATH=$PATH:$HOME/.SpaceVim/bin
+```
+
+Use `svc` to open a file in the existing Vim server.
