+# Contributing Guide
+
+Before submitting your contribution, please make sure to take a moment and read through the following guidelines:
+
+- [Pull Request Guidelines](#pull-request-guidelines)
+- [Development Setup](#development-setup)
+- [Scripts](#scripts)
+- [Project Structure](#project-structure)
+- [Contributing Tests](#contributing-tests)
+
+## Pull Request Guidelines
+
+- The master branch is just a snapshot of the latest stable release. All development should be done in dedicated branches. Do not submit PRs against the master branch.
+
+- Checkout a topic branch from a base branch, e.g. `master`, and merge back against that branch.
+
+- If adding a new feature add accompanying test case.
+
+- It's OK to have multiple small commits as you work on the PR - GitHub can automatically squash them before merging.
+
+- Make sure tests pass!
+
+- Commit messages must follow the [commit message convention](./commit-convention.md). Commit messages are automatically validated before commit (by invoking [Git Hooks](https://git-scm.com/docs/githooks) via [husky](https://github.com/typicode/husky)).
+
+- No need to worry about code style as long as you have installed the dev dependencies - modified files are automatically formatted with Prettier on commit (by invoking [Git Hooks](https://git-scm.com/docs/githooks) via [husky](https://github.com/typicode/husky)).
+
+## Development Setup
+
+You will need [Node.js](https://nodejs.org) **version 16+**.
+
+After cloning the repo, run:
+
+```bash
+$ npm i # install the dependencies of the project
+```
+
+A high level overview of tools used:
+
+- [Jest](https://jestjs.io/) for unit testing
+- [Prettier](https://prettier.io/) for code formatting
+
+## Scripts
+
+### `npm run lint`
+
+The `lint` script runs linter.
+
+```bash
+# lint files
+$ npm run lint
+# fix linter errors
+$ npm run lint:fix
+```
+
+### `npm run test`
+
+The `test` script simply calls the `jest` binary, so all [Jest CLI Options](https://jestjs.io/docs/en/cli) can be used. Some examples:
+
+```bash
+# run all tests
+$ npm run test
+
+# run all tests under the runtime-core package
+$ npm run test -- runtime-core
+
+# run tests in a specific file
+$ npm run test -- fileName
+
+# run a specific test in a specific file
+$ npm run test -- fileName -t 'test name'
+```
+
+## Project Structure
+
+- **`src`**: contains the source code
+
+  - **`api`**: contains group of methods and methods for the API.
+
+  - **`helpers`**: contains utilities shared across the entire codebase.
+
+    - **`tests`**: contains tests for the helpers directory.
+
+  - **`tests`**: contains tests for the src directory.
+
+## Contributing Tests
+
+Unit tests are collocated with the code being tested inside directories named `tests`. Consult the [Jest docs](https://jestjs.io/docs/en/using-matchers) and existing test cases for how to write new test specs. Here are some additional guidelines:
+
+- Use the minimal API needed for a test case. For example, if a test can be written without involving the reactivity system or a component, it should be written so. This limits the test's exposure to changes in unrelated parts and makes it more stable.
+
+- Only use platform-specific runtimes if the test is asserting platform-specific behavior.
