+# Dependencies
+
+This plugin depends on common POSIX utilities (awk, grep, sed, etc.), Bash, Git, and Go. If you have a Go toolchain installed and selected via asdf (asdf current golang), it will be used to retrieve and build oapi-codegen. Otherwise, asdf will be used to retrieve the latest Go version and that will be used for the build.
+
 # Install
 
 Plugin:
 
 ```shell
-asdf plugin add oapi-codegen
-# or
 asdf plugin add oapi-codegen https://github.com/dylanrayboss/asdf-oapi-codegen.git
 ```
