# Exercise 9: Referencing using target headers
It can be really useful to refer to a specific section in your book while working in a different file. Referencing can be done using target headers such as:
```
(<title>)=
```
1. Navigate to the file you want to work in (for example `book/some_content/overview.md`) and make sure you're in the correct branch.
2. Identify the section you want to reference and name it between brackets for example `exercise_`1.
```
(exercise_1)=
# Exercise 1: First file edit
Let's start with the most basic edit: add some text to a file and see that the website is updated...
```
3. Referencing
There are three types of referencing:
* If you want to refernce in line you can use:
My favourite exercise was {ref}`exercise_1`.
```
My favourte exercise was {ref}`exercise_1`.
```
* You can also specify the in-line text of the target (aka what the link will say):
{ref}`Best exercise <exercise_1>`
* Another alternative is to use Markdown syntax:
[Best exercose](exercise_1)
