+Loading data in Google Colab notebooks
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Google Colab is a hosted Jupyter notebook environment. Since it runs remotely,
+files must be explicitly uploaded or mounted before they can be read by pandas.
+
+Uploading local files
+^^^^^^^^^^^^^^^^^^^^^
+
+Files can be uploaded directly to the Colab runtime using ``google.colab.files``:
+
+.. code-block:: python
+
+   from google.colab import files
+   uploaded = files.upload()
+
+   import pandas as pd
+   df = pd.read_csv("data.csv")
+
+Using Google Drive
+^^^^^^^^^^^^^^^^^
+
+Google Drive can be mounted to make files available to the runtime:
+
+.. code-block:: python
+
+   from google.colab import drive
+   drive.mount("/content/drive")
+
+   import pandas as pd
+   df = pd.read_csv("/content/drive/MyDrive/data.csv")
+
+Loading data from a URL
+^^^^^^^^^^^^^^^^^^^^^^
+
+Data hosted remotely can be read directly using a URL:
+
+.. code-block:: python
+
+   import pandas as pd
+
+   url = (
+       "https://raw.githubusercontent.com/pandas-dev/pandas/main/"
+       "doc/data/air_quality_no2.csv"
+   )
+   df = pd.read_csv(url)
