+# Contributing to vLLM-Spyre
 
 Thank you for your interest in contributing to Spyre support on vLLM!
 
-When submitting a PR, please make sure your code passes all linting checks:
+There are several ways you can contribute:
 
-## Linting
+- Identify and report any issues or bugs.
+- Suggest or implement new features.
+- Improve documentation or contribute a how-to guide.
 
-You can install the linting requirements using either `uv` or `pip`.
+## Issues
 
-Using `uv`:
-
-```bash
-uv sync --frozen --group lint --active --inexact
-```
-
-Using `pip`:
-
-```bash
-uv pip compile --group lint > requirements-lint.txt
-pip install -r requirements-lint.txt
-```
+If you encounter a bug or have a feature request, please search [existing issues](https://github.com/vllm-project/vllm-spyre/issues?q=is%3Aissue) first to see if it has already been reported. If not, please [create a new issue](https://github.com/vllm-project/vllm-spyre/issues/new/choose), providing as much relevant information as possible.
 
-After installing the requirements, run the formatting script:
-
-```bash
-bash format.sh
-```
-
-Then, make sure to commit any changes made by the formatter:
-
-```bash
-git add .
-git commit -s -m "Apply linting and formatting"
-```
-
-Now, you’re good to go! 🚀

-We can debug using `debugpy` in VS code.
-
- This is the content of the `launch.json` file which we need for debugging in VS code:
-
-```sh
