 In this example we will be using [KaTeX](https://katex.org/)
 
-- Create a partial under `/layouts/partials/math.html`
-- Within this partial reference the [Auto-render Extension](https://katex.org/docs/autorender.html) or host these scripts locally.
-- Include the partial in your templates like so:  
-
-```bash
-{{ if or .Params.math .Site.Params.math }}
-{{ partial "math.html" . }}
-{{ end }}
-```
-
-- To enable KaTex globally set the parameter `math` to `true` in a project's configuration
-- To enable KaTex on a per page basis include the parameter `math: true` in content files
+- To enable KaTeX globally, set the parameter `math` to `true` in a project's
+  configuration:
+  - `config.toml`
+    ```toml
+    [params]
+      math = true
+    ```
+  - `config.yaml`
+    ```yaml
+    params:
+      math: true
+    ```
+- To enable KaTeX on a per page basis, include the parameter `math: true` in
+  Front Matter of Markdown content files:
+
+  ```
+  ---
+  math: true
+  ---
+  ```
