+## Actions specifying HTML values
+
+To use HTML in actions you must encode the HTML string. We recommend using [CyberChef](https://gchq.github.io/CyberChef/#recipe=To_HTML_Entity(false,'Numeric%20entities')). Using CyberChef or a similar tool is straightforward: enter in your HTML string, copy the encoded result, and paste that value into your MFTF test.
+
+For example, we want to ensure that this value is presented as a string and not rendered as a H1 tag: `<h1 class="login-header">`
+
+After passing `<h1 class="login-header">` through CyberChef we get `&#60;h1 class&#61;&#34;login-header&#34;&#62;` which can be used in a test like:
+
+```xml
+<dontSeeInSource html="&#60;h1 class&#61;&#34;login-header&#34;&#62;" stepKey="dontSeeInSource"/>
+```
