 Long posts can also include multiple ordered step images. Upload them under **Step images**, then place `[[image:1]]`, `[[image:2]]`, and so on directly in the article text where each repair step needs an image. Each step image supports an optional caption and opens full-size when selected.
 
+To add a code snippet, place it between triple-backtick fences. Add an optional language name after the opening fence to label the snippet:

+````text
+```python
+print("hello, circuit")
+```
+````
+
+Code is displayed as literal text and can be copied from the article view. Image markers written inside a code fence remain literal text.
