+# Contributing to Glass
+
+Thank you for considering contributing to **Glass by Pickle**! Contributions make the open-source community vibrant, innovative, and collaborative. We appreciate every contribution you make—big or small.
+
+## 📌 Contribution Guidelines
+
+### 👥 Avoid Work Duplication
+
+Before creating an issue or submitting a pull request (PR), please check existing [Issues](https://github.com/pickle-com/glass/issues) and [Pull Requests](https://github.com/pickle-com/glass/pulls) to prevent duplicate efforts.
+
+### ✅ Start with Approved Issues
+
+- **Feature Requests**: Please wait for approval from core maintainers before starting work. Issues needing approval are marked with the `🚨 needs approval` label.
+- **Bugs & Improvements**: You may begin immediately without explicit approval.
+
+### 📝 Clearly Document Your Work
+
+Provide enough context and detail to allow easy understanding. Issues and PRs should clearly communicate the problem or feature and stand alone without external references.
+
+### 💡 Summarize Pull Requests
+
+Include a brief summary at the top of your PR, describing the intent and scope of your changes.
+
+### 🔗 Link Related Issues
+
+Use GitHub keywords (`Closes #123`, `Fixes #456`) to auto-link and close issues upon PR merge.
+
+### 🧪 Include Testing Information
+
+Clearly state how your changes were tested.
+
+> Example:  
+> "Tested locally on macOS 14, confirmed all features working as expected."
+
+### 🧠 Future-Proof Your Descriptions
+
+Document trade-offs, edge cases, and temporary workarounds clearly to help future maintainers understand your decisions.

+# Developing
+
+### Prerequisites
+
+Ensure the following are installed:
+- [Node.js v20.x.x](https://nodejs.org/en/download)
+- [Python](https://www.python.org/downloads/)
+- (Windows users) [Build Tools for Visual Studio](https://visualstudio.microsoft.com/downloads/)
+
+Ensure you're using Node.js version 20.x.x to avoid build errors with native dependencies.
+
+```bash
+# Check your Node.js version
+node --version
+
+# If you need to install Node.js 20.x.x, we recommend using nvm:
+# curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
+# nvm install 20
+# nvm use 20
+```
+
+## Setup and Build
+
+```bash
+npm run setup
+```
+Please ensure that you can make a full production build before pushing code.
+
+
+
+## Linting
+
+```bash
+npm run lint
+```
+
+If you get errors, be sure to fix them before committing.
+
+
+## Making a Pull Request
+
+- Be sure to [check the "Allow edits from maintainers" option](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/allowing-changes-to-a-pull-request-branch-created-from-a-fork) when creating your PR. (This option isn't available if you're [contributing from a fork belonging to an organization](https://github.com/orgs/community/discussions/5634))
+- If your PR refers to or fixes an issue, add `refs #XXX` or `fixes #XXX` to the PR description. Replace `XXX` with the respective issue number. See more about [linking a pull request to an issue](https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue).
+- Lastly, make sure to keep your branches updated (e.g., click the `Update branch` button on the GitHub PR page).
