 1. Using `append_single_option_line` with a second string argument for the wiki page.  
 
-   ```cpp
-   optgroup->append_single_option_line("[OPTION_NAME]"); // Option without wiki page/redirection
-   optgroup->append_single_option_line("[OPTION_NAME]", "[WIKI_LINK]"); // Option with wiki page and redirection
-   ```
+    ```cpp
+    optgroup->append_single_option_line("[OPTION_NAME]"); // Option without wiki page/redirection
+    optgroup->append_single_option_line("[OPTION_NAME]", "[WIKI_LINK]"); // Option with wiki page and  redirection

-   ```cpp

-   optgroup->append_single_option_line("seam_slope_type", "quality_settings_seam#scarf-joint-seam"); // Wiki page and redirection to `Scarf Joint Seam` section

+    optgroup->append_single_option_line("seam_gap","quality_settings_seam"); // Wiki page and redirection
+    optgroup->append_single_option_line("seam_slope_type", "quality_settings_seam#scarf-joint-seam"); // Wiki  page and redirection to `Scarf Joint Seam` section
+    ```
 
 2. Using `append_option_line` with a third string argument for the wiki page.
 
-   ```cpp
-   append_option_line([optgroup], [opt_key], "[WIKI_LINK]");
-   ```
+    ```cpp
+    append_option_line([optgroup], [opt_key], "[WIKI_LINK]");
+    ```
 
     Example:
 
-   ```cpp
-   append_option_line(optgroup, "machine_max_acceleration_x", "printer_motion_ability#acceleration-limitation");
-   ```
+    ```cpp
+    append_option_line(optgroup, "machine_max_acceleration_x", "printer_motion_ability#acceleration-limitation");
+    ```
 
 3. Using grouped rows with `append_line` and setting the wiki target via `line.label_path`.
 
-   ```cpp
-   line.label_path = "[WIKI_LINK]";
-   ```
+    ```cpp
+    line.label_path = "[WIKI_LINK]";
+    ```
 
     Example:
 
-   ```cpp
-   Line line = { L("Overhang speed"), L("...") };
-   line.label_path = "speed_settings_overhang_speed#slow-down-for-overhang";
-   line.append_option(optgroup->get_option("overhang_1_4_speed"));
-   optgroup->append_line(line);
-   ```
+    ```cpp
+    Line line = { L("Overhang speed"), L("...") };
+    line.label_path = "speed_settings_overhang_speed#slow-down-for-overhang";
+    line.append_option(optgroup->get_option("overhang_1_4_speed"));
+    optgroup->append_line(line);
