+## Updating the configuration options for lsp-haskell
+
+1. Generate the vscode settings file
+
+```sh
+haskell-language-server-9.6.2 vscode-extension-schema > /tmp/schema.json
+```
+Add `{"contributes": {"configuration": { "properties":`
+to the top and
+`}}}` to the bottom.
+
+2. Generate the settings snippet
+
+Make sure you have https://github.com/emacs-lsp/lsp-mode/blob/master/scripts/lsp-generate-settings.el
+on your machine somewhere. In this example it is at `/tmp/lsp-generate-settings.el`
+
+In emacs, activate IELM, `M-x ielm`
+
+In IELM,
+
+```elisp
+(load-library "/tmp/lsp-generate-settings.el")
+;; Do direct output to buffer
+(defun p (x) (move-end-of-line 0) (insert (format "\n%s" x)))
+(p (lsp-generate-settings "/tmp/schema.json" 'lsp-haskell))
+```
+
+This will emit settings that do not currently exist in the running
+emacs instance.
+
+Edit them into [lsp-haskell.el](./lsp-haskell.el)
