+---
+--- 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.
+---
+--- ```lua
+--- vim.lsp.config('powershell_es', {
+---   bundle_path = 'c:/w/PowerShellEditorServices',
+--- })
+--- ```
+---
+--- By default the language server is started in `pwsh` (PowerShell Core). This can be changed by specifying `shell`.
+---
+--- ```lua
+--- vim.lsp.config('powershell_es', {
+---   bundle_path = 'c:/w/PowerShellEditorServices',
+---   shell = 'powershell.exe',
+--- })
+--- ```
+---
+--- Note that the execution policy needs to be set to `Unrestricted` for the languageserver run under PowerShell
+---
+--- If necessary, specific `cmd` can be defined instead of `bundle_path`.
+--- See [PowerShellEditorServices](https://github.com/PowerShell/PowerShellEditorServices#standard-input-and-output)
+--- to learn more.
+---
+--- ```lua
+--- vim.lsp.config('powershell_es', {
+---   cmd = {'pwsh', '-NoLogo', '-NoProfile', '-Command', "c:/PSES/Start-EditorServices.ps1 ..."},
