+### HTML escape
+
+By default, HTML tags are escaped. You can enable HTML tags rendering
+by setting `security.markdwon_escape` to `false` in `data/config.json.php`:
+
+```json
+{
+ "security": {
+ "markdown_escape": false
+ }
+}
+```
+
+With this setting, Markdown support HTML tags. For example:
+
+ > <strong>strong</strong><strike>strike</strike>
+
+Will render as:
+
+> <strong>strong</strong><strike>strike</strike>
+
+
+**Warning:**
+
+ * This setting might present **security risks** (XSS) on shared instances, even though tags
+ such as script, iframe, etc should be disabled.
+ * If you want to shaare HTML code, it is necessary to use inline code or code blocks.
+ * If your shaared descriptions contained HTML tags before enabling the markdown plugin,
+enabling it might break your page.
