-You can install additional PyPI packages and import your own Python packages. See [Python Packages](../piplines/python-packages.md) for more details.
+## PyPI packages
+
+You can install additional PyPI packages and import them your handlers. Cortex looks for a `requirements.txt` file in the top level Cortex project directory (i.e. the directory which contains `cortex.yaml`):
+
+```text
+./iris-classifier/
+├── cortex.yaml
+├── handler.py
+├── ...
+└── requirements.txt
+```
+
+## Project files
+
+Cortex makes all files in the project directory (i.e. the directory which contains `cortex.yaml`) available to pre and post inference handlers. Python generated files and files and folders that start with `.` are excluded.
+
+The contents of the project directory is available in `/mnt/project/` in the API containers. For example, if this is your project directory:
+
+```text
+./iris-classifier/
+├── cortex.yaml
+├── config.json
+├── handler.py
+├── ...
+└── requirements.txt
+```
+
+You can access `config.json` in `handler.py` like this:
+
+```python
+import json
+
+with open('/mnt/project/config.json', 'r') as config_file:
+  config = json.load(config_file)
+
+def pre_inference(sample, metadata):
+  print(config)
+  ...
+```
+
+## System packages
+
+You can also install additional system packages. See [System Packages](system-packages.md) for more details.
