 This layer adds supports [Language Server Protocol](https://langserver.org/).
 
-## Requrement
+## Install
+
+To use this configuration layer, add it to your `~/.spacevim`, set it up like so:
+
+```vim
+let g:spacevim_layers = [
+      \ 'lsp',
+      \ ]
+```
+
+Currently [LanguageClient-neovim](https://github.com/autozimu/LanguageClient-neovim) is the default *language server client* when using the lsp layer.
+
+Currently the *language server client* builtin to Neovim is not supported by space-vim [#483](https://github.com/liuchengxu/space-vim/issues/483).
+
+To use [coc.nvim](https://github.com/neoclide/coc.nvim) or [vim-lsp](https://github.com/prabirshrestha/vim-lsp) instead of the default set `g:spacevim_lsp_engine` as desired:
+
+```vim
+let g:spacevim_layers = [
+      \ 'lsp',
+      \ ]
+
+let g:spacevim_lsp_engine = 'coc'
+let g:spacevim_lsp_engine = 'vim_lsp'
+```
+
+Note that coc.nvim is dependent on Node.js, the nodejs layer will satisfy that dependency.
+
+If using vim-lsp as the *language server client*, this layer will handle the configuration and installation of many *language servers* for you (this layer includes the [vim-lsp-settings](https://github.com/mattn/vim-lsp-settings) plugin). On opening a file this layer will detect if there is a *language server* for that filetype and prompt you to run the command `:LspInstallServer`.
+
+Unlike other Vim *language server clients*, LanguageClient-neovim does not include configuration and installation of *language servers*. space-vim includes some configuration for *language servers* and this client, but installation must be done manually.
+
+Often the Yarn or npm tools are needed to retrieve a *language server* and its dependencies. For convenience space-vim includes these tools within the nodejs layer, which builds them or locates them using the `$PATH` and `$NODE` environmental variables. You may include the nodejs layer as follows (which may require the programming layer):
+
+```vim
+let g:spacevim_layers = [
+      \ 'programming', 'nodejs', 'lsp',
+      \ ]
+```
+
+## Manual Language Server Installation
+
+If using LanguageClient-neovim, directions for the manual installation of some LSP servers are as follows. Other configuration and installation directions can be found in locations like its github wiki pages.

+
+## Description
+
+Folowing the zero-install philosophy, this layer adds the Node.js tool, built from source if needed.
+
+If `node` is found on $PATH, or $NODE points to `node`, and either is of sufficient version, that will be used instead of building from source.
+
+The curated node will be added to `$PATH` for use by other plugins and language servers. Including yarn/npm which language servers may use to download dependencies.
+
+## Install
+
+To use this layer, add it to your `~/.spacevim`.
+
+### Building
+
+On building from source, around 200MiB is installed into the prefix `./install` relative to the plugin directory. The building process requires around 4GiB, which will be deleted on completion.
+
+If the automated building doesn't work, you may navigate to the plugin directory and build manually, into the prefix `./install`; installing system-wide isn't required. Or install prebuilt binaries and set $PATH or $NODE accordingly.
+
+#### MS Windows
+
+You have two ABI choices: GNU and MSVC (comes with Visual Studio Tools). Your choice depends on the C/C++ libraries you want to interoperate with.
+
+Automated building from source isn't tested. However it should work in Cygwin or with the environmental variables as defined by `msys2_shell.cmd` or `vcvars64.bat` per the desired ABI.
