+To register a LSP server, add the following lines to your .vimrc file:
+>
+   let lspServers = [
+               \     {
+               \       'filetype': ['c', 'cpp'],
+               \       'path': '/usr/local/bin/clangd',
+               \       'args': ['--background-index']
+               \     },
+               \     {
+               \       'filetype': ['javascript', 'typescript'],
+               \       'path': '/usr/local/bin/typescript-language-server',
+               \       'args': ['--stdio']
+               \     }
+               \     {
+               \       'filetype': 'sh',
+               \       'path': '/usr/local/bin/bash-language-server',
+               \       'args': ['start']
+               \     },
+               \   ]
+   call lsp#addServer(lspServers)
+<
+The above lines add the LSP servers for C, C++, Javascript, Typescript and
+Shell script file types.
+
+To add a LSP server, the following information is needed:
+
+       filetype        One or more file types supported by the LSP server.
+                       This can be a |String| or a |List|. To specify
+                       multiple multiple file types, use a List.
+       path            complete path to the LSP server executable (without
+                       any arguments).
+       args            a list of command-line arguments passed to the LSP
+                       server. Each argument is a separate List item.
+
+The LSP servers are added using the lsp#addServer() function. This function
+accepts a list of LSP servers with the above information.
