# Router Tags

* If you navigate to the DOCS page

{% hint style="info" %}
Usually <http://127.0.0.1:8000/docs>
{% endhint %}

* Tags will allow us to group this documentation based on responsibility
* Basically grouping them in "folders"
* This is very easy to update
* Withing the `router` variable we will have to add the tag

```python
# post.py

# Before:
router = APIRouter(
    prefix="/posts"
)

# After:
router = APIRouter(
    prefix="/posts",
    tags=['Posts']
)

# user.py

# Before:
router = APIRouter(
    prefix="/users"
)

# After:
router = APIRouter(
    prefix="/users",
    tags=['Users']
)
```

* Now this has updated our sections as follows:
