Thanks for helping us test **Libraries 2.0** , which is currently in beta in each of our three primary development tools: - Command Line interface (CLI) - Desktop IDE (Dev) - Web IDE (Build) Please read this [draft documentation about Libraries 2.0](https://github.com/spark/docs/blob/libraries-docs/src/content/reference/libraries.md) before continuing with the installation of these beta tools. **NOTE** : You need to make sure that your Particle device is running [v0.5.3 or later](https://github.com/spark/firmware/releases/tag/v0.5.3) in order to take advantage of the new Libraries 2.0 architecture. All applications that are migrated to the new project structure required by Libraries 2.0 **will only work on devices running v053 or later** , and migration is non-reversible. ## The purpose of this post is to: - Provide everyone with the most up-to-date instructions for testing Libraries 2.0 in their Particle IDE of choice (CLI, Dev, Build) - Serve as a changelog that notifies users of new versions of our beta tools and the improvements that have been made in the new release ##Getting Started ### 1. Web IDE (Build) **Current version** : Always up-to-date **Installation** : `http://build-canary.particle.io` To test Libraries 2.0 with Build, simply log into your Particle account at **[https://build-canary.particle.io](https://build-canary.particle.io)**. All changes will be deployed there in real time–no need to download, update, or install to take advantage of our latest development efforts. ### 2. Desktop IDE (Dev) **Current version** : v0.2.16 **Installation** : To use Libraries 2.0 in Particle Dev, follow these instructions: 1. Open Atom or Particle Dev 2. Reveal command palette (Cmd+Shift+P on macOS and Ctrl+Shift+P on Windows/Linux) 3. Type “install packages” and select **Settings View: Install Packages and Themes** 4. Search for `particle-dev-libraries` 5. Click **Install** next to the package **Updating** : To update the Atom package (`particle-dev-libraries`) that facilitates Libraries 2.0, navigate to the Settings screen of Particle Dev by selecting **Atom** \> **Preferences**. Go to the **Updates** tab and click the **Check for Updates** button. This will update your `particle-dev-libraries` package to the most recent version available. Consult [Readme](https://github.com/spark/particle-dev-libraries#readme) for usage instructions. ### 3. Command Line Interface (CLI) **Current version** : v1.19.0-libraries.23 **Installation** : Installing the Particle CLI is a simple process. Simply type the following npm command into your terminal: `npm install -g https://github.com/spark/particle-cli/releases/download/v1.19.0-libraries.23/particle-cli-1.19.0-libraries.23.tgz` ---

I just fixed the link to the beta Web IDE in case you were wondering why it didn’t work 😉 **[https://build-canary.particle.io](https://build-canary.particle.io)** ---
