+Language server for PowerShell.
+
+To install, download and extract PowerShellEditorServices.zip
+from the [releases](https://github.com/PowerShell/PowerShellEditorServices/releases).
+To configure the language server, set the property `bundle_path` to the root
+of the extracted PowerShellEditorServices.zip.
+
+The default configuration doesn't set `cmd` unless `bundle_path` is specified.
+
+```lua
+require'lspconfig'.powershell_es.setup{
+  bundle_path = 'c:/w/PowerShellEditorServices',
+}
+```
+
+If necessary, specific `cmd` can be defined instead of `bundle_path`.
+See [PowerShellEditorServices](https://github.com/PowerShell/PowerShellEditorServices#stdio)
+to learn more.
+
+```lua
+require'lspconfig'.powershell_es.setup{
+  cmd = {'pwsh', '-NoLogo', '-NoProfile', '-Command', "c:/PSES/Start-EditorServices.ps1 ..."}
+}
+```
+]];
+    default_config = {
+      root_dir = "git root or current directory";
