+# Contributing
+
+Hi! I'm really excited that you are interested in contributing to Vorms. Before submitting your contribution, please make sure to take a moment and read through the following guide:
+
+## Repo Setup
+
+The Vorms repo is a monorepo using pnpm workspaces. The package manager used to install and link dependencies must be [pnpm](https://pnpm.io/).
+
+Here is a quick guide to doing code contributions to the library.
+
+1. Fork and clone the repo to your local machine
+
+    ```bash
+    git clone https://github.com/YOUR_GITHUB_USERNAME/vorms.git
+    ```
+
+    ```bash
+    pnpm install
+    ```
+
+2. Create a new branch from `master` with a meaningful name for a new feature or an issue you want to work on
+3. If you've added a code that should be tested, ensure the test suite still passes.
+
+    ```bash
+    pnpm test
+    ```
+
+     Try to write some unit tests to cover as much of your code as possible.
+
+4. Ensure your code lints without errors
+
+    ```bash
+    pnpm lint
+    ```
+
+5. Ensure build passes.
+
+    **@vorms/core**
+
+    ```bash
+    pnpm build:core
+    ```
+
+    **@vorms/resolvers**
+
+    ```bash
+    pnpm build:resolvers
+    ```
+
+6. Push your branch.
+7. Submit a pull request to the upstream vorms repository.
+8. Choose a descriptive title and describe your changes briefly.
+
+## Coding style
+
+Please follow the coding style of the project. Vorms uses eslint and prettier. If possible, enable their respective plugins in your editor to get real-time feedback. The linting can be run manually with the following command: `pnpm lint` and `pnpm format`
