+# Contributing to Unified InstantSearch for Ecommerce
+
+Welcome to the contributing guide for Unified InstantSearch for Ecommerce!
+
+If this guide does not contain what you are looking for and thus prevents you from contributing, don't hesitate to [let us know](https://github.com/algolia/unified-instantsearch-ecommerce/issues/new).
+
+## Reporting an issue
+
+Opening an issue is very effective way to contribute because many users might also be impacted. We'll make sure to fix it quickly if it's technically feasible and doesn't have important side effects for other users.
+
+Before reporting an issue, first check that there is not an already open issue for the same topic using the [issues page](https://github.com/algolia/unified-instantsearch-ecommerce/issues). Don't hesitate to thumb up an issue that corresponds to the problem you have.
+
+Another element that will help us go faster at solving the issue is to provide a reproducible test case.
+
+## Code contribution
+
+For any code contribution, you need to:
+
+- Make sure that the code change has been discussed in [Issues](https://github.com/algolia/unified-instantsearch-ecommerce/issues)
+- Fork and clone the project
+- Create a new branch for what you want to solve ("fix/<u>issue-number</u>", "feat/<u>name-of-the-feature</u>")
+- Make your changes
+- Open a pull request
+
+Then:
+
+- A team member will review the pull request
+
+When every check is green and a team member approves, your contribution is merged! 🚀
+
+## Commit conventions
+
+This project follows the [conventional changelog](https://conventionalcommits.org/) approach. This means that all commit messages should be formatted using the following scheme:
+
+```
+type(scope): description
+```
+
+This convention is used to generate the [changelog](https://github.com/algolia/unified-instantsearch-ecommerce/tree/master/CHANGELOG.md).
+
+In most cases, we use the following types:
+
+- `fix`: for any resolution of an issue (identified or not)
+- `feat`: for any new feature
+- `refactor`: for any code change that neither adds a feature nor fixes an issue
+- `docs`: for any documentation change or addition
+- `chore`: for anything that is not related to the library itself (e.g., doc, tooling)
+
+Even though the scope is optional, we try to fill it in as it helps us better understand the impact of a change.
+
+Finally, if your work is based on an issue on GitHub, please add in the body of the commit message "Closes #1234" if it solves the issue #1234 (read "[Closing issues using keywords](https://help.github.com/en/articles/closing-issues-using-keywords)").
+
+Some examples of valid commit messages (used as first lines):
+
+> - fix(js): increase magnifying glass size
+> - feat(core): add `enterKeyHint` input prop
+> - refactor(core): inline `navigator` default prop
+> - docs(state): add `query` state property
+> - docs(readme): add "Showcase" section
+> - chore(deps): update dependency rollup-plugin-babel to v3.0.7
+
+## Installation
+
+### Requirements
+
+To run this project, you will need:
+
+- Node.js ([nvm](https://github.com/creationix/nvm#install-script) is recommended)

+
+```sh
+yarn

-**This project aims to be used by any e-commerce website to bootstrap a search experience powered by Algolia the fastest way possible.**
+Build your Ecommerce Search & Discovery experience in no time using this framework-agnostic prebuilt UI that offers out-of-the-box a robust as-you-type InstantSearch experience, while retaining the customizability of [Algolia InstantSearch](https://www.algolia.com/doc/guides/building-search-ui/what-is-instantsearch/js/).
 
-While you would still have to push your data to Algolia, the goal of Unified InstantSearch E-Commerce is to remove the need to implement front-end logic and be able to start using Algolia as quickly as possible.
+Designed to accelerate your Algolia integration, this mobile-optimised UI has been created to best fit any website UI via its full page overlay and offers a direct access to the following Algolia key features:
+
+- Typo proof as-you-type InstantSearch experience
+- Query Suggestions
+- Advanced Analytics with A/B testing
+- Dynamic Re-ranking
+- Personalization
+- Merchandising capabilities, including banners via Rules
+
+On the frontend side, once compiled, the total package weighs under 300kb and runs on any existing website, regardless of the framework used (see [Browser support](#browser-support)). Its impact on Core Vitals is almost transparent.
