+          In the examples above, you can generally use usernames instead of <mark class="green">uuid</mark>. However, apart from the special cases <code><a href="/renders/body/0?default=MHF_Steve" target="_blank">MHF_Steve</a></code> and <code><a href="/renders/body/0?default=MHF_Alex" target="_blank">MHF_Alex</a></code> this is discouraged as explained below.<br>

+          <h3><a href="#meta-parameters">URL Parameters</a></h3>
+          <p>
+            You can tweak images using <a href="https://en.wikipedia.org/wiki/Query_string" target="_blank">query string parameters</a>.<br>
+            Example: <code><%= domain %>/avatars/853c80ef3c3749fdaa49938b674adae6<mark class="blue">?</mark><mark class="green">size=4</mark><mark class="blue">&</mark><mark class="green">default=MHF_Steve</mark><mark class="blue">&</mark><mark class="green">helm</mark></code>
+          </p>
+          <ul>
+            <li><b>size</b>: The size of the image in pixels. <code><%= config.avatars.min_size %> - <%= config.avatars.max_size %></code>
+            <li><b>scale</b>: The scale factor renders. <code><%= config.renders.min_scale %> - <%= config.renders.max_scale %></code>
+            <li><b>helm</b>: Apply the <span title="Also known as 'hat' or 'jacket' or 'helm'">overlay</span> to the avatar. Presence of this parameter implies <code>true</code>.
+            <li>
+              <b>default</b>: The fallback to be used when the requested image cannot be served. You can use a <span title="Make sure to properly percent-encode this!">custom URL</span> or any <mark class="green">uuid</mark>.<br>
+              The option defaults to either <code>MHF_Steve</code> or <code>MHF_Alex</code>, depending on the requested UUID. All usernames default to <code>MHF_Steve</code>.
