+
+Entropy is an extensible infrastructure orchestration and application deployment tool. Entropy provides features required for deploying and managing complex applications like resource versioning, config schema versioning, rollbacks dry runs etc.
+
+## Key Features
+
+- **No Dependency:** Written in Go. It compiles into a single binary with no external dependency.
+- **Extensible:** Entropy provides framework to easily write and deploy applications to your choice of cloud
+- **Runtime:** Entropy can run inside VMs or containers with minimal memory footprint.
+
+## Documentation
+
+Explore the following resources to get started with Entropy:
+
+- [Configuration](./docs/reference/configuration.md) to get familar with configuring Entropy.
+
+## Installation
+
+Install Entropy on macOS, Windows, Linux, OpenBSD, FreeBSD, and on any machine.
+
+#### Binary (Cross-platform)
+
+Download the appropriate version for your platform from [releases](https://github.com/odpf/entropy/releases) page. Once downloaded, the binary can be run from anywhere.
+You don’t need to install it into a global location. This works well for shared hosts and other systems where you don’t have a privileged account.
+Ideally, you should install it somewhere in your PATH for easy use. `/usr/local/bin` is the most probable location.
+
+#### Homebrew
+
+```sh
+# Install entropy (requires homebrew installed)
+$ brew install odpf/taps/entropy
+
+# Upgrade entropy (requires homebrew installed)
+$ brew upgrade entropy
+
+# Check for installed entropy version
+$ entropy version
+```
+
+## Usage
+
+Entropy typically runs as a service and requires a MongoDB to store its state.
+
+## Running locally
+
+```sh
+# Clone the repo
+$ git clone https://github.com/odpf/entropy.git
+
+# Build entropy binary file
+$ make build
+
+# Start a MongoDB instance
+$ docker-compose up
+
+# Run entropy on a recipe file
+$ ./entropy serve
+
+```
+
+## Running tests
+
+```sh
+# Running all unit tests, excluding extractors
+$ make test
+```
+
