+- **Modularization:** plugins and functions are organized in [layers](https://spacevim.org/layers/).
+- **Compatible api:** a series of [compatible APIs](https://spacevim.org/api/) for Vim/Neovim.
+- **Great documentation:** online [documentation](https://spacevim.org/documentation/) and `:h SpaceVim`.
+- **Better experience:** rewrite core plugins using lua
+- **Beautiful UI:** you'll love the awesome UI and its useful features.
+- **Mnemonic key bindings:** key binding guide will be displayed automatically
+- **Fast boot time:** Lazy-load 90% of plugins with [dein.vim](https://github.com/Shougo/dein.vim)
+- **Lower the risk of RSI:** by heavily using the space bar instead of modifiers.
+- **Consistent experience:** consistent experience between terminal and gui
