-SpaceVim is a vim configuration inspired by spacemacs, it is compatible with Vim and Neovim.
+SpaceVim is a (neo)vim configuration inspired by spacemacs.
 
 ## Features
 
 - **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
+- **Better experience:** [Use lua to implement core plugins](https://spacevim.org/use-lua-to-reimplement-core-plugins/)
 - **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)

+# [Blogs](../blog/) >> Use Lua to Reimplement Core Plugins
+
+After comparing the speed of vim script and lua, I want to rewrite SpaceVim with Lua.
+
+**NOTE:** All vim scripts will be retained to ensure support for older versions of Vim and NeoVim

+### How to compare speed
+
+with following vim script, and run:
+
+- `:TestFunc Fibo 1000`
+- `:TestFunc Fibo 10000000`
+- `:TestFunc LuaFibo 1000`
+- `:TestFunc LuaFibo 10000000`
+
+```viml
+function! Fibo(N) abort
+    let t = a:N
+    let b = 0
+    while t > 0
+        let t = t - 1
+        let a = 1
+        let b = 1
+        let c = 73
+        while c > 0
+            let c = c - 1
+            let tmp = a + b
+            let a = b
+            let b = tmp
+        endwhile
+    endwhile
+    echo b
+endfunction
+
+function! LuaFibo(N) abort
+lua << EOF
+local a, b, r, c, t
+t = vim.api.nvim_eval("str2nr(a:N)")
+while t > 0 do
+        t = t - 1
+        a = 1
+        b = 1
+        c = 73
+        while c > 0 do
+                c = c - 1
+                r = a + b
+                a = b
+                b = r
+        end
+end
+
+print(string.format("%d", b))
+EOF
+endfunction
+function! s:test(...) abort
+        " for func in a:000
+                let start = reltime()
+                call call(a:1,[a:2])
+                let sec = reltimefloat(reltime(start))
+                echom printf('%s(%d): %.6g sec', a:1, a:2, sec)
+        " endfor
+endfunction
+
+command! -nargs=+ TestFunc call s:test(<f-args>)
+```
+
+results:
+
+```
+Fibo(1000): 0.410364 sec
+Fibo(10000000): 1470.280914 sec
+LuaFibo(1000): 9.052000e-4 sec
+LuaFibo(10000000): 1.235385 sec
+```
+
+
+### Which version of neovim should I use?
+
+It is recommended to use neovim 0.9.0 or 0.9.1
+
+### What has been done?
+
+**Basic:**
+
+- The spacevim runtime logger
+
+The default runtime logger can be used in in both vim script and lua script. For example:
+
+```lua
+-- in lua script test.lua
+
+local log = require('spacevim.logger').derive('test')
+
+local function test_foo()
+  log.debug('this is debug message')
+end
+
+test_foo()
+```
+
+Then the runtime log via `SPC h L`, and you should be able to see:
+
+```
+[     test ] [17:14:56:907] [ Debug ] this is debug message
+```
+
+**APIs:**
+
+- [file](../api/file/)
+- [system](../api/system/)
+- [logger](../api/logger/) 
+- [job](../api/job/)
+- [data#toml](../api/data/toml/)
+- [notify](../api/notify/)
+
+**Built-in Plugins:**
+
+These plugins are very commonly used in SpaceVim, so they are rewritten using lua for a better experience.
+
+- alternate file manager
+
+  Use `:A {type}` to jump to alternate file quickly.
+
+- projectmanager
+
+  The project manager provides the function of quickly switching to the project root directory.
+
+- key binding guide
+- code runner
+- flygrep
+- The REPL plugin
