title: Open 'ipython notebook' as: IPython notebook vs Jupyter
body: <p>I expected to find more documentation on the following:</p>
  <blockquote>
  <p><strong>From one computer: <code>C:\Python&gt;ipython notebook</code> opens the browser as <em>'IPython Notebook'</em>.</strong></p>
  <p><strong>From second computer: <code>C:\Python&gt;ipython notebook</code> opens the browser as <em>'Jupyter'</em>.</strong></p>
  </blockquote>
  <p>I dont have a preference, but <strong>when saving from the <em>'Jupyter'</em> browser, I can no longer open a .ipnb file in the <em>'IPython Notebook'</em> browser</strong>.  I encounter a <strong>&quot;bad request&quot;</strong> error.</p>
  <p>Initially I assumed that 'ipython notebook' had been updated to use 'Jupyter' as its browser so I updated (<code>pip install &quot;ipython[notebook]&quot;</code>) on both computers with no effect.  Clearly I am missing something.</p>
  <hr />
  <p><strong>Did <code>ipython notebook</code> switch to using <em>Jupyter</em>?  If so, am I incorrectly updating IPython?</strong></p>
