+# Word Cloud Generator
+
+## General Info
+
+This is a Python script that when run, creates a filter word cloud from the summary of tickets over a time period.
+
+The script takes ~10 seconds to complete on a month of tickets
+
+Unit tests exist which test the logic of the methods the script uses, and the tests should be run whenever changes are made to the code.
+
+## Requirements
+
+requests: 2.31.0
+parameterized: 0.9.0
+python-dateutil: 2.8.2
+wordcloud: 1.9.2
+
+## Setup
+Running the script:
+```
+$ cd ../word_cloud_generator
+$ pip install -r requirements.txt
+$ python3 word_cloud_generator.py
+```
+
+Running the unit tests:
+```
+$ python3 -m unittest discover -s ./test -p "test_*.py"
+```
