+## Objective
 
 The original objective of the Facebook [Nuclide](https://nuclide.io) / [Atom-IDE](https://ide.atom.io) project has been to provide extension packages for the [Atom Editor](https://www.atom.io) to interact with custom Language Servers via the [Language Server Protocol](https://langserver.org) to enable IDE like functionality in our beloved editor.
 
 The original package was made of various "subpackages" that provide the overall functionality and were always build and released in a monolithic extension (aka atom-ide-ui).
 
 The objective of this project is to take over the concepts and ideas in the original atom-ide-ui package, but provide individual extensions that can be developed, released and installed independently.
 
-We will start with the most important features, and iterate on them quickly to come on par with the functionality available in the atom-ide-ui package.   
+We will start with the most important features, and iterate on them quickly to come on par with the functionality available in the atom-ide-ui package.
+
+
+## Getting Started
+
+So far, there have been a few features from the original atom-ide-ui package that have been created as individual packages. Here are the steps required to start using IDE features in your Atom Text Editor using the new community packages.
+
+1. Install an IDE language package that you would like to use:
+* TypeScript & JavaScript [ide-typescript](https://atom.io/packages/ide-typescript)
+* Python [ide-python](https://atom.io/packages/ide-python)
+* Rust [ide-rust](hhttps://atom.io/packages/ide-rust)
+* You can also search for [packages](https://atom.io/packages/search?q=IDE) in Atom.
+
+2. Install any of the [community packages](https://atom.io/users/atom-ide-community) listed below.
+
+3. Enjoy!
