 ## Getting Started
 
+### Operating System Compatibility
+
+| O/S    | Status   |
+| :---------------- | :------: |
+| Android        | ✅ |
+| FreeBSD        | ✅ |
+| LCARS          | 🛸 | 
+| Linux          | ✅ |
+| MacOS          | ✅ | 
+| OS/2 Warp      | ❌ |
+| Windows (WSL2) | ✅ |
+

 ### Prerequisites
 
-- A Unix-like operating system: macOS, Linux, BSD. On Windows: WSL2 is preferred, but cygwin or msys also mostly work.
 - [Zsh](https://www.zsh.org) should be installed (v4.3.9 or more recent is fine but we prefer 5.0.8 and newer). If not pre-installed (run `zsh --version` to confirm), check the following wiki instructions here: [Installing ZSH](https://github.com/ohmyzsh/ohmyzsh/wiki/Installing-ZSH)
 - `curl` or `wget` should be installed
 - `git` should be installed (recommended v2.4.11 or higher)

+## rtx
+
+
+Adds integration with [rtx](https://github.com/jdx/rtx), a runtime executor compatible with npm,  nodenv, pyenv, etc. rtx is written in rust and is very fast. 20x-200x faster than asdf. With that being said, rtx is compatible with asdf plugins and .tool-versions files. It can be used as a drop-in replacement.
+
+### Installation
+
+1. [Download & install rtx](https://github.com/jdx/rtx#installation) by running the following:
+
+  ```
+  curl https://rtx.pub/install.sh | sh
+  ```
+
+
+2. [Enable rtx](https://github.com/jdx/rtx#quickstart) by adding it to your `plugins` definition in `~/.zshrc`.
+
+  ```
+  plugins=(rtx)
+  ```
+
+### Usage
+
+See the [rtx readme](https://github.com/jdx/rtx#table-of-contents) for information on how to use rtx. Here are a few examples:
+
+```
+rtx install node         Install the current version specified in .tool-versions/.rtx.toml
+rtx use -g node@system   Use system node as global default
+rtx install node@20.0.0  Install a specific version number
+rtx use -g node@20       Use node-20.x as global default
+```
