<p>You can easily tweak the script after download. The settings
and strings are in the beginning of the script. In the HTML
snippets you can modify the size of the button in the
<tt>style</tt> attribute of the <tt>&lt;img&gt;</tt> tag, which
is set to <tt>height: 32px</tt> and change the <tt>src</tt>
attribute to adjust the path to the button image. You can also
adjust the fallback links, but you can't remove the
<tt>&lt;a&gt;</tt> tags.</p>

&lt;/head&gt;</pre>
<p>You need to make sure the paths are correct in the
<tt>href</tt> and <tt>src</tt> attributes. Your account is
embedded in the script and can be changed by assigning a new
account to <tt>MastodonInteract.account</tt>. You can also
change the text for the share button with
<tt>MastodonInteract.sharetext</tt>.</p>
<p>The two HTML snippets need to be copy pasted to the part of
your page where you want to insert the buttons. Make sure that
the paths to the icons are correct and point to where you
uploaded the generated icons.</p>
