+# C
+
+C is a common programming language.
+In this entry we will focus on making vim support c and use vim as an ide for c.
+
+## Autocompletion
+
+### Coc
+
+To enable autocompletion for coc you need to install `ccls`.
+After that you need to add the following lines to your coc config file.
+
+```json
+{
+   "languageserver": {
+       "ccls": {
+           "command": "ccls",
+           "filetypes": [
+               "c",
+               "cpp",
+               "objc",
+               "objcpp"
+           ],
+           "rootPatterns": [
+               ".ccls",
+               "compile_commands.json",
+               ".vim/",
+               ".git/",
+               ".hg/"
+           ],
+           "initializationOptions": {
+               "cache": {
+                   "diretory": "/tmp/ccls"
+               }

+  - Add `Plug 'neoclide/coc.nvim', {'do': 'yarn install --frozen-lockfile'}`
+  to your Plug-Section
+
+## Base config
+
+Add the base configuration to your vim config file.
+
+```vimscript
+" neoclide/coc.nvim
+inoremap <silent><expr> <TAB>
+      \ pumvisible() ? "\<C-n>" :
+      \ <SID>check_back_space() ? "\<TAB>" :
+      \ coc#refresh()
+inoremap <expr><S-TAB> pumvisible() ? "\<C-p>" : "\<C-h>"
+
+function! s:check_back_space() abort
+  let col = col('.') - 1
+  return !col || getline('.')[col - 1]  =~# '\s'
+endfunction
+
+if has('nvim')
+  inoremap <silent><expr> <c-space> coc#refresh()
+else
+  inoremap <silent><expr> <c-@> coc#refresh()
+endif
+
+inoremap <silent><expr> <cr> pumvisible() ? coc#_select_confirm()
+                              \: "\<C-g>u\<CR>\<c-r>=coc#on_enter()\<CR>"
+
+nmap <silent> gd <Plug>(coc-definition)
+nmap <silent> gy <Plug>(coc-type-definition)
+nmap <silent> gi <Plug>(coc-implementation)

+
+function! s:show_documentation()
+  if (index(['vim','help'], &filetype) >= 0)
+    execute 'h '.expand('<cword>')
+  elseif (coc#rpc#ready())
+    call CocActionAsync('doHover')
+  else
+    execute '!' . &keywordprg . " " . expand('<cword>')

+## Extensions
+
+Extensions can be added to the vim config aswell.
+A basic example for adding a few extensions is:
+
+```vimscript
