 5. Now, let's explore three different ways to reference this section or chapter! For the first method, we use the standard title text by calling the identifier as follows. This will display: My favourite exercise was {ref}`exercise_1`.
 
-  ```md
-  My favourite exercise was {ref}`exercise_1`.
-  ```
+```md
+My favourite exercise was {ref}`exercise_1`.
+```
 
 
 6. For the second method, we want to refer to the section using a custom title text. Try this out by placing the text that you want to be displayed within `` and calling the identifier within <>. 
 This will display: My favourite exercise was {ref}`the first one <exercise_1>`.
 
-  ```md
-  My favourite exercise was {ref}`the first one <exercise_1>`.
-  ```
+```md
+My favourite exercise was {ref}`the first one <exercise_1>`.
+```
 
 
 7. The last method uses markdown syntax to also display a custom title text. Refer to the desired section once again, this time by putting the custom text within [] and calling the identifier within <> as shown below. This will display: My favourite exercise was [this one](exercise_1).
 
 
-  ```md
-  My favourite exercise was [this one](exercise_1).
