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