+### [BamboohrUserExtractor](./databuilder/extractor/user/bamboohr/bamboohr_user_extractor.py)
+
+The included `BamboohrUserExtractor` provides support for extracting basic user metadata from [BambooHR](https://www.bamboohr.com/).  For companies and organizations that use BambooHR to store employee information such as email addresses, first names, last names, titles, and departments, use the `BamboohrUserExtractor` to populate Amundsen user data.
+
+A sample job config is shown below.
+
+```python
+extractor = BamboohrUserExtractor()
+task = DefaultTask(extractor=extractor, loader=FsNeo4jCSVLoader())
+
+job_config = ConfigFactory.from_dict({
+    'extractor.bamboohr_user.api_key': api_key,
+    'extractor.bamboohr_user.subdomain': subdomain,
+})
+
+job = DefaultJob(conf=job_config,
+                 task=task,
+                 publisher=Neo4jCsvPublisher())
+job.launch()
+```
