+## Getting Started
+
+## Run using Docker
+1. Install Docker on [Windows](https://docs.docker.com/docker-for-windows/), [Mac](https://docs.docker.com/docker-for-mac/) or [Linux](https://docs.docker.com/install/).
+2. Navigate to the directory where you have the input files.
+3. Run RePlAce container:
+
+       docker run -it -v $(pwd):/data openroad/replace bash
+
+4. From the interactive bash terminal, use RePlAce scripts which reside under `/RePlAce`. You can read input files from `/data` directory inside the docker container - which mirrors the host machine directory you are in. 
+
+* The Docker image is self-contained and includes everything that RePlAce needs to work properly.
+
+## Install on a bare-metal machine
