+There are quite a lot of sequence diagram drawing tools available. If this one
+doesn't fit your needs for whatever reason, you might want to take a look at the
+alternatives:
+</p>
+<ul>
+
+<li><a href="https://www.websequencediagrams.com/" target="_blank">websequencediagrams.com</a>
+is a commercial offering which inspired the syntax of this project and many
+others. It has a wide range of themes but limited functionality. Also offers a
+hosted image generation service.</li>
+
+<li><a href="https://github.com/bramp/js-sequence-diagrams" target="_blank">js-sequence-diagrams</a>
+is a Javascript library which has wider browser support via snap.svg but very
+limited functionality.</li>
+
+<li><a href="https://github.com/knsv/mermaid" target="_blank">mermaid</a>
+is a Javascript library and online editor which can render multiple types of UML
+diagram, including simple sequence diagrams.</li>
+
+<li><a href="https://github.com/aivarsk/scruffy" target="_blank">Scruffy UML</a>
+is a Python library which can render multiple types of UML diagram, including
+simple sequence diagrams, from the commandline. Uses yUML syntax rather than the
+human friendly syntax used by most other projects.</li>
+
+<li><a href="https://github.com/plantuml/plantuml" target="_blank">PlantUML</a>
+is a Java project and online editor which can render multiple types of UML
+diagram, including sequence diagrams. Has a good range of features and allows a
+high degree of customisation (e.g. diagram colours).</li>
