-# llm_regression
+# Regression using LLMs
 
-This is the repository for the llm_regression Python package.
+The llm_regression package demonstrates how LLMs can be used to solve classical regression problems, and exposes these capabilities for you to experiment with. Example:
+
+```python
+from llm_regression import OpenAiRegressor
+
+llm_regressor = OpenAiRegressor(model="gpt-3.5-turbo")
+llm_regressor.fit(X_train, y_train)
+y_pred = llm_regressor.predict(X_test)
+```
+
+This work was motivated by the paper,
+
+["_From Words to Numbers: You LLM is Secretly a Capable Regressor_", by Vacareanu et al. (2024)](https://arxiv.org/abs/2404.07544).
+
+Which is well worth a read!
+
+## Installing
+
+You can install the llm_regression package, together with the dependencies required to run the example notebooks, directly from this repo,
+
+```text
+pip install -U pip
+pip install "llm_regression[examples] @ git+https://github.com/AlexIoannides/llm-regression.git"
+```
+
+## Examples
+
+Checkout the [basic_demo notebook](https://github.com/AlexIoannides/llm-regression/tree/main/examples/basic_demo.ipynb).
 
 ## Developer Setup
 
+If you want to modify or extend the work in this repo, then the information in this section is for you.
+
+### Install Developer Tools
+
 Install the package as an [editable dependency](https://setuptools.pypa.io/en/latest/userguide/development_mode.html), together with all the developer tools required to format code, check types and run tests:
 
 ```text
-$ pip install -e ".[dev]"
+pip install -e ".[dev]"
 ```

-### Building Packages and Deploying to PyPI
-
-This is automated via the `nox -s build_and_deploy` command. In order to use this, the following environment variables will need to be made available to Python:
-
-```text
-PYPI_USR  # PyPI username
-PYPI_PWD  # PyPI password
+nox > Session run_tests-3.12 was successful.
 ```
 
-These may be specified in a `.env` file from which they will be loaded automatically - e.g.,
-
-```text
-PYPI_USR=XXXX
-PYPI_PWD=XXXX
-```
-
-Note: `.gitignore` will ensure that `.env`is not tracked by Git.
-
-## CI/CD
+### CI/CD
 
 This repo comes configured to run two [GitHub Actions](https://docs.github.com/en/actions) workflows:
 
 - **Test Python Package (CI)**, defined in `.github/workflows/python-package-ci.yml`
 - **Deploy Python Package (CD)**, defined in `.github/workflows/python-package-cd.yml`
 
 The CI workflow has been configured to run whenever a pull request to the `main` branch is created. The CD workflow has been configured to run whenever a [release](https://docs.github.com/en/repositories/releasing-projects-on-github/managing-releases-in-a-repository) is created on GitHub.
-
-Note, the CD workflow will require `PYPI_USR` and `PYPI_PWD` to be added as [repository secrets](https://docs.github.com/en/actions/security-guides/using-secrets-in-github-actions).
