 ## Features and usage
 
+### 0) Editor toolbar: Code block button
+
+The plugin adds a custom button to the DokuWiki editor toolbar for quickly inserting `<code>` blocks.
+
+When editing a page, click the code block button (angle brackets icon `<>`) in the toolbar to wrap selected text in `<code></code>` tags, or to insert an empty code block at the cursor position.
+
+This complements DokuWiki's built-in monospace formatting (`''`) by providing quick access to HTML code blocks.
+
 ### 1) List files by glob pattern
