@@ -121,3 +121,37 @@ The `simulator` directory contains a deterministic simulator for testing.
121121
What this means is that the behavior of a test run is deterministic based on the seed value.
122122
If the simulator catches a bug, you can always reproduce the exact same sequence of events by passing the same seed.
123123
The simulator also performs fault injection to discover interesting bugs.

## Python Bindings
126+
127+
Limbo provides Python bindings built on top of the [PyO3](https://pyo3.rs) project.
128+
To compile the Python bindings locally, you first need to create and activate a Python virtual environment (for example, with Python `3.12`):
129+
130+
```bash
131+
python3.12 -m venv venv
132+
source venv/bin/activate
133+
```
134+
135+
Then, install [Maturin](https://pypi.org/project/maturin/):
136+
137+
```bash
138+
pip install maturin
139+
```
140+
141+
Once Maturin is installed, you can build the crate and install it as a Python module directly into the current virtual environment by running:
142+
143+
```bash
144+
cd bindings/python && maturin develop
145+
```
146+
147+
## Adding Third Party Dependencies
148+
149+
When you want to add third party dependencies, please follow these steps:
150+
151+
1. Add Licenses: Place the appropriate licenses for the third-party dependencies under the licenses directory. Ensure
152+
that each license is in a separate file and named appropriately.
153+
2. Update NOTICE.md: Specify the licenses for the third-party dependencies in the NOTICE.md file. Include the name of
154+
the dependency, the license file path, and the homepage of the dependency.
155+
156+
By following these steps, you ensure that all third-party dependencies are properly documented and their licenses are
157+
included in the project.
