title: I'm trying to setup showoff.io or localtunnel on a Mac, but I'm stuck
body: <p>I installed the gem according to the instructions at <a href="https://showoff.io/" rel="nofollow">showoff.io</a>, but when I try to run</p>
  
  <pre><code>show 8888
  </code></pre>
  
  <p>it doesn't work and I get</p>
  
  <pre><code>-bash: show: command not found
  </code></pre>
  
  <p>In their <a href="https://showoff.io/support#faq" rel="nofollow">faq</a>, they mention running </p>
  
  <pre><code>gem contents showoff-io
  </code></pre>
  
  <p>if that happens, but I don't know how to read what I get:</p>
  
  <pre><code>Rakefile
  Gemfile
  lib/showoff/client.rb
  lib/showoff/settings.rb
  lib/showoff/api.rb
  lib/showoff/helpers.rb
  lib/showoff/version.rb
  lib/showoff/setup.rb
  lib/showoff/session.rb
  lib/showoff.rb
  bin/show
  </code></pre>
  
  <p>They say this:</p>
  
  <blockquote>
    <p>This will list all of the files in the showoff-io gem. Look for the bin/show script. Either add that folder to your $PATH, or symlink the script into a location already on your $PATH. For example: </p>
  </blockquote>
  
  <pre><code>sudo ln -s /var/ruby/gems/.../bin/show /usr/local/bin
  </code></pre>
  
  <p>But obviously copy&amp;pasting that doesn't do anything because those are just example paths. </p>
  
  <p>I'm sure this is very basic, but I'm a novice at this. What do I have to do?</p>
  
  <p>Thanks!</p>
