title: asdf commands not working even though it's installed
body: <p>Does anyone have much experience setting up asdf with zsh? I'm installing it via git. It appears to be installed as typing &quot;asdf&quot; in terminal returns a list of asdf commands, however, if I go to use one of those commands like &quot;asdf version&quot; or &quot;asdf plugin list-all&quot; it returns:</p>
  <p><code>Unknown command: 'asdf version'</code></p>
  <p><code>No plugin named update</code></p>
  <p>I think it may be an issue with the path. Any advice welcome.</p>
