 This dataset has bounding boxes for ~6000 hand annotated pages with bounding boxes for figures, figure captions, tables, and math formulas.
 
 More coverage is available for figures + captions (some pages might not have all tables and math formulas annotated).

+## How to use this data
+
+To plot an example check out the [trial_example_from_data.ipynb](https://huggingface.co/datasets/ReadingTimeMachine/historical_dla/blob/main/trial_example_from_data.ipynb) notebook.
+
+This assumes you have the data and the [data_utils.py](https://huggingface.co/datasets/ReadingTimeMachine/historical_dla/blob/main/data_utils.py) file in the same location as your notebook.
+
+The following packages will have to be installed:
+```python
+matplotlib
+numpy
+pandas
+wand
+PIL
+wget
+cv2 # OpenCV
+```
+
+On Google Colab, to install `wand` we found we had to do the following (this is not in the linked notebook):
+
+```python
+!apt install imagemagick
+!apt-get install libmagickwand-dev
+
+!pip install Wand
+
+!rm /etc/ImageMagick-6/policy.xml
+
+!pip install wget
+```
