+## Telemetry
+
+ElixirLS language server sends telemetry information to the client via [LSP Telemetry notification](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#telemetry_event), [DAP Output event](https://microsoft.github.io/debug-adapter-protocol/specification#Events_Output) and [DAP ErrorResponse](https://microsoft.github.io/debug-adapter-protocol/specification#Base_Protocol_ErrorResponse). Telemetry data include usage, performance, environment info and error reports. Please refer to your client and/or extension documentation on telemetry.

 ## Acknowledgements and related projects
 
 ElixirLS isn't the first frontend-independent server for Elixir language support. The original was [Alchemist Server](https://github.com/tonini/alchemist-server/), which powers the [Alchemist](https://github.com/tonini/alchemist.el) plugin for Emacs. Another project, [Elixir Sense](https://github.com/elixir-lsp/elixir_sense), builds upon Alchemist and powers the [Elixir plugin for Atom](https://github.com/msaraiva/atom-elixir) as well as another VS Code plugin, [VSCode Elixir](https://github.com/fr1zle/vscode-elixir). ElixirLS uses Elixir Sense for several code insight features. Credit for those projects goes to their respective authors.

+# Incomplete OTP installations
+
 Incomplete installations is a frequent cause of ElixirLS failures. Generally
 this is resolved by:
-* Installing elixir and erlang with ASDF https://github.com/asdf-vm/asdf
+
+* Installing elixir and erlang via [ASDF](https://github.com/asdf-vm/asdf) or [RTX](https://github.com/jdx/rtx)
   (recommended)
-* Installing a full version of Erlang via the package manager
+* Installing a full version of Erlang/OTP via the package manager
