+The Options class allows the download of options data from Yahoo! Finance.
+
+The ''get_all_data'' method downloads and caches option data for all expiry months
+and provides a formatted ''DataFrame'' with a hierarchical index, so its easy to get
+to the specific option you want.
+
+.. ipython:: python
+
+      from pandas.io.data import Options
+      aapl = Options('aapl', 'yahoo')
+      data = aapl.get_all_data()
+      data.head()
+
+      #Show the $600 strike puts at all expiry dates:
+      data.loc[(600, slice(None), 'put'),:].head()
+
+      #Show the volume traded of $600 strike puts at all expiry dates:
+      data.loc[(600, slice(None), 'put'),'Vol'].head()
+
+If you don't want to download all the data, more specific requests can be made.
+
+.. ipython:: python
+
+      import datetime
+      expiry = datetime.date(2016, 1, 1)
+      data = aapl.get_call_data(expiry=expiry)
+      data.head()
+
+Note that if you call ''get_all_data'' first, this second call will happen much faster, as the data is cached.
