+# Schema Language Server in Neovim
+
+## Requirements
+Requires java to be excutable on the system.
+
+Optional: [lspconfig](https://github.com/neovim/nvim-lspconfig) plugin for nvim.
+
+## Installation
+Download `schema-language-server-jar-with-dependencies.jar`.
+
+### Using lspconfig
+Register `.sd` and `.profile` as filetypes (in `init.lua`):
+```lua
+vim.filetype.add {
+  extension = {
+    profile = 'sd',
+    sd = 'sd'
+  }
+}
+```
+
+Create a config for schema language server (in `init.lua`):
+```lua
+local lspconfig = require "lspconfig"
+local configs = require "lspconfig.configs"
+
+if not configs.schemals then
+    configs.schemals = {
+        default_config = {
+            filetypes = { 'sd' },
+            cmd = { 'java', '-jar', '/path/to/schema-language-server-jar-with-dependencies.jar' },
+            root_dir = lspconfig.util.root_pattern('.')
+        },
+    }
+end
+
+lspconfig.schemals.setup{
+    -- optional on_attach function for setting keybindings etc.
+    on_attach = function(client, bufnr)
+       	-- local opts = {buffer = bufnr, remap = false}
+	    -- vim.keymap.set("n", "gd", function() vim.lsp.buf.definition() end, opts)
+    end
+}
+```
+
+### Manual Installation
+If you don't want to use lspconfig you can refer to the [LSP documentation for Neovim](https://neovim.io/doc/user/lsp.html) for manually registering the server.
