+<p>Experimental builds are intended for testing and evaluation of new gameplay and map features.
+The current experimental builds are specifically for testing the following new features:</p>
+<ul>
+  <li><a href="https://github.com/ddnet/ddnet/pull/9793">Tune lock tiles</a></li>
+  <li><a href="https://github.com/ddnet/ddnet/pull/9917">Ninja tunes (duration, movetime, velocity)</a></li>
+  <li><a href="https://github.com/ddnet/ddnet/pull/10514">Variable laser length tile</a></li>
+  <li><a href="https://github.com/ddnet/ddnet/pull/11398">Envelope trigger tiles</a></li>
+  <li><a href="https://github.com/ddnet/ddnet/pull/11541">Weapon ammo with switch tiles</a></li>
+</ul>
+<p>For details about the individual features, refer to the links above.
+If you encounter bugs with the new features, please report them by commenting on the respective Pull Request linked above
+or in the #bugs channel on our <a href="https://ddnet.org/discord">Discord server</a>.
+If you encounter bugs unrelated to the new features, please report them by opening an issue on <a href="https://github.com/ddnet/ddnet/issues">GitHub</a>
+or in the #bugs channel on our Discord server.</p>
+<p>Maps making use of these experimental features cannot be officially released until the features have also been finalized and released.
+However, at the same time, these features require feedback from map testers before they can be released,
+in order to reduce the likelyhood of any gameplay bugs in the final released features and to avoid feature bloat.
+To release an individual, experimental feature, it is required that at least one pilot map is developed and ready to be released,
+which is up to DDNet's map standards and covers most, if not all, reasonable uses of the new feature.
+While you can also test experimental features in combination with each other to find any potential issues,
+each pilot map should only make use of exactly one experimental feature to test and showcase it.
+Depending on the feedback from map testers, these features may be changed before being released.
+Features may also not be released at all if they do not work out as expected or if they are not compelling enough for a pilot map.</p>
