+# Wizer plugin
+
+[Wizer](https://github.com/bytecodealliance/wizer) plugin for [proto](https://github.com/moonrepo/proto).
+
+## Installation
+
+This is a community plugin and is thus not built-in to proto. In order to use it, first either add it to your global or project-based `.prototools` by running:
+
+### Global install
+
+```shell
+proto plugin add wizer "source:https://raw.githubusercontent.com/Phault/proto-toml-plugins/main/wizer/plugin.toml" --global
+proto install wizer
+```
+
+### Per-project install
+
+```shell
+proto plugin add wizer "source:https://raw.githubusercontent.com/Phault/proto-toml-plugins/main/wizer/plugin.toml"
+proto pin wizer latest --resolve
+```
