 # Contributing to OpenLLMetry
 
-Thanks for taking the time to contribute! 😃 🚀
+We welcome contributions of all sizes to OpenLLMetry! Thank you for considering contributing to our project.
+
+## Overview
+
+It's the early days of our project, and we’re dedicated to building an awesome, inclusive community. To foster this environment, all community members must adhere to our [Code of Conduct](CODE_OF_CONDUCT.md).
+
+## Getting Started
+
+### Community
+
+Join our [Slack community](https://traceloopcommunity.slack.com/join/shared_invite/zt-1plpfpm6r-zOHKI028VkpcWdobX65C~g#/shared-invite/email) to chat and get help with any issues you may encounter.
+
+### Bugs and Issues
+
+Bug reports help make OpenLLMetry a better experience for everyone. When you report a bug, a template will be created automatically to gather necessary information.
+
+Before raising a new issue, please search existing ones to avoid duplicates. If the issue is related to security, please email us directly at [[email protected]](mailto:[email protected]).
+
+## Deciding What to Work On
+
+You can start by browsing through our list of [issues](https://github.com/traceloop/openllmetry/issues) or adding your own to improve the test suite experience. Once you've decided on an issue, leave a comment and wait for approval to avoid multiple contributors working on the same task.
+
+If you're unsure whether a proposed feature aligns with OpenLLMetry, feel free to raise an issue about it, and we'll respond promptly.
+
+## Writing and Submitting Code
+
+Anyone can contribute code to OpenLLMetry. To get started, check out the **Local Development Guide** below, make your changes, and submit a pull request to the main repository.
+
+## Licensing
+
+All of OpenLLMetry’s code is under the Apache 2.0 license. Any third-party components incorporated into our code are licensed under the original license provided by the respective component owner.
+

+
+## Local Development
+
+You can contribute by adding new instrumentations or updating and improving the different SDKs.
+
+### Environment Setup
+
+The Python and TypeScript projects are monorepos that use `nx` to manage the different packages. Ensure you have Node.js version 18 or higher and `nx` installed globally.
+
+#### Basic Guide for Using `nx`
+
+Most commands can be run from the root of the project. For example, to lint the entire project, run:
+
+```bash
+nx run-many -t lint
+```
+You can also use other commands similarly: `test`, `build`, `lock`, and `install` (for Python).
+
+To run a specific command on a specific package, use:
+
+```bash
+nx run <package>:<command>
+```
+### Python Development
+We use `poetry` to manage packages, and each package is managed independently under its own directory in `/packages`. All instrumentations depend on `opentelemetry-semantic-conventions-ai`, and `traceloop-sdk` depends on all the instrumentations.
+
+When adding a new instrumentation, make sure to use it in `traceloop-sdk` and write proper tests.
+
+### Debugging
+Regardless of whether you’re working on an instrumentation or the SDK, we recommend testing your changes using the SDK in the sample app located in `/packages/sample-app` or running tests under the SDK.
+
+Running Tests
+We record HTTP requests and then replay them in tests to avoid making actual calls to the foundation model providers. See `vcr.py` and `pollyjs` for more details on usage and re-recording requests.
+
+To run all tests, execute:
+```bash
+nx run-many -t test
+```
+To run a specific test, use:
+```bash
+
+nx run <package>:test
+```
+For example, to run the tests for the OpenAI instrumentation package, run:
+
+```bash
+nx run opentelemetry-instrumentation-openai:test
+```
+### TypeScript Development
+We use `npm` with workspaces to manage packages in the monorepo. Install dependencies by running:
+
+```bash
+npm install
+```
+Each package has its own test suite. You can use the sample app to run and test changes locally.
+
+Thank you for your interest in contributing to OpenLLMetry! We look forward to collaborating with you!
