+# Typescript-Tutorial-Exercises Contributing Guide
+
+Hi! I'm really excited that you are interested in contributing to js-sdsl. Before submitting your contribution, please make sure to take a moment and read through the following guidelines:
+
+- [Code of Conduct](https://github.com/typescript-tutorial-exercises/core/blob/main/CODE_OF_CONDUCT.md)
+- [Issue Reporting Guidelines](#issue-reporting-guidelines)
+- [Pull Request Guidelines](#pull-request-guidelines)
+- [Development Setup](#development-setup)
+- [Project Structure](#project-structure)
+
+## Issue Reporting Guidelines
+
+- Always use issue-template to create new issues.
+
+## Pull Request Guidelines
+
+- The `main` branch is just a snapshot of the latest stable release. All development should be done in dedicated branches. **Do not submit PRs against the `main` branch.**
+
+- Checkout a topic branch from the relevant branch, e.g. `dev`, and merge back against that branch.
+
+- Work in the `src` folder and **DO NOT** check in `dist` in the commits.
+
+- It's OK to have multiple small commits as you work on the PR - GitHub will automatically squash it before merging.
+
+- Make sure it works fine in local environment. (see [development setup](#development-setup))
+
+- If adding a new feature:
+  - Provide a convincing reason to add this feature. Ideally, you should open a suggestion issue first and have it approved before working on it.
+
+- If fixing bug:
+  - If you are resolving a special issue, add `(fix #xxxx[,#xxxx])` (#xxxx is the issue id) in your PR title for a better release log, e.g. `update entities encoding/decoding (fix #3899)`.
+  - Provide a detailed description of the bug in the PR. Live demo preferred.
+  - Add appropriate test coverage if applicable.
+
+## Development Setup
+
+You will need [Node.js](http://nodejs.org) **version 16+** and [yarn](https://yarnpkg.com/).
+
+After cloning the repo, run:
+
+```bash
+$ yarn setup
+```
+
+### Committing Changes
+
+Please follow the commit specification. See [`.commitlintrc.json`](https://github.com/typescript-tutorial-exercises/core/blob/main/.commitlintrc.json) get help.
+
+### Commonly used NPM scripts
+
+```bash
+# run project in development mode
+$ yarn dev
+# build all dist files
+$ yarn build
+```
+
+There are some other scripts available in the `scripts` section of the `package.json` file.
+
+## Project Structure
+
+- **`assets`**: contains static files of the site
+- **`config`**: contains configuration files
+- **`src`**: contains the source code
+- **`problems`**: contains all the problems
+
+All our source files are written in typescript, please make sure your submissions have strict type deduction and follow eslint specifications.
