## What is Bit? 🤔
Bit is an [open-source](https://github.com/teambit/bit) cli tool for collaborating on isolated components across projects and repositories.
Use Bit to distribute discrete components from a design library or a project into a standalone reusable package and utilize it across applications.
You can set up your own server for components collaboration, or use the [bit.dev cloud](#bitdev-cloud-%EF%B8%8F) hosting for private and public components sharing.
## Why Bit? 🎖️
Bit facilitates the process of collaborating on UI components. Team members can share, maintain, and synchronize isolated components from different projects.
Bit allows teams to:
- Increase code reusability
- Increase design and development efficiency
- Retain UI and UX consistency
- Increase project's stability
## Key Features 🔑
- Extract a component for sharing directly from an existing library or project.
- Validate the component's independence by building and testing each component separately from the rest of the project.
- Change the source code of shared components from any application that utilizes it.
- Get published changes in components on top of local modifications.
- Contribute back changes made to components directly from the consuming applications.
- Automatically wrap each component as an npm package.
- Distribute discrete components instead of a single massive package.
- Automate component versioning according to changes in its dependencies.
- Use with leading frameworks and tools: React, Vue, Angular, Mocha, Jest.
- Works alongside Git, NPM, and Yarn.
Bit is working with Javascript and Javascript frameworks:
## Installation 🚪

```
Using yarn:
```bash
yarn global add bit-bin
```
Bit cli requires node 8.12 and above. Check other [installation](https://docs.bit.dev/docs/installation) methods.
## bit.dev cloud 🌩️
Use [bit.dev](https://bit.dev) cloud hosting solution as a shared server and showcase for your components.
