 ** Language Server Protocol Support
-This module must be enabled with the =+lsp= flag, and the =:tools lsp= module
-must be enabled. LSP will try pyls then mspyls; the first that is available.
+For LSP support the =:tools lsp= module must be enabled, along with this
+module's =+lsp= flag. By default, it supports =mspyls= and =pyls=, in that
+order. With the =+pyright= flag, it will try Pyright first.
 
-*To use [[https://pypi.org/project/python-language-server/][Python Language Server]] (pyls)* install it with ~pip install
-'python-language-server[all]'~
+Each of these servers must be installed on your system via your OS package
+manager or manually:
 
-*To use mspyls*, install it with ~M-x lsp-install-server~ and add this to your
-private config.el:
-
-#+BEGIN_SRC elisp
-(after! lsp-python-ms
-  (set-lsp-priority! 'mspyls 1))
-#+END_SRC
-
-*To use pyright*, install it from your shell with with ~npm i -g pyright~.
++ [[https://pypi.org/project/python-language-server/][*pyls*]] can be installed with ~pip install python-language-server[all]~.
++ *mspyls* can be installed by typing =M-x lsp-install-server RET mspyls=.
++ *pyright* can be installed with ~pip install pyright~ or ~npm i -g pyright~.
 
 * Features
 This module supports LSP. It requires installation of [[https://pypi.org/project/python-language-server/][Python Language
 Server]], [[https://github.com/Microsoft/python-language-server][Microsoft Language Server]], or [[https://github.com/microsoft/pyright][pyright]], see [[Language Server Protocol Support][LSP Support]].
