 `angular-language-server` can be installed via npm `npm install @angular/language-server`.
 Be aware there is no global binary and must be run via `node_modules/@angular/language-server/index.js` which can be added as the default cmd.
+
+Note, that if you override the default `cmd`, you must also update `on_new_config` to set `new_config.cmd` during startup.

+```lua
+local project_library_path = "/path/to/project/lib"
+local cmd = {"node", "/path/to/node_modules/@angular/language-server/index.js", "--stdio", "--tsProbeLocations", project_library_path , "--ngProbeLocations", project_library_path}
+
+require'lspconfig'.angularls.setup{
+  cmd = cmd,
+  on_new_config = function(new_config,new_root_dir)
+    new_config.cmd = cmd
+  end,
+}
