+## `our-tag`
+This tag helper attribute can be seamlessly integrated with any DOM element within the Razor file. It allows content editors to oversee SEO by designating the appropriate HTML tags for distinct elements. Consider a scenario where you have an item in your block list named 'Heading Tag' - maybe it's from a predefined dropdown? This is saved as a straightforward string. Your block view then fetches this value through the model, making it accessible for the 'our-tag' tag helper.
+
+### Example 1
+```
+// Model.Heading = "This is my heading"
+// Model.HeadingTag = "H1"
+<h2 class="my-heading" our-tag="@Model.HeadingTag">@Model.Heading</h2>
+```
+
+#### Output
+The hardcoded `h2` has been replaced with an `h1` element tag.
+```
+<h1 class="my-heading">This is my heading</h1>
+```
+
+### Example 2
+```
+// Model.Heading = "This is my heading"
+// Model.HeadingTag = ""
+<h2 class="my-heading" our-tag="@Model.HeadingTag">@Model.Heading</h2>
+```
+
+#### Output
+Defaults to the original hardcoded element tag:
+```
+<h2 class="my-heading">This is my heading</h2>
+```
