+# Dockerfile for Micro-GW Base Image #
+
+This section defines the step-by-step instructions to build an [Ubuntu](https://hub.docker.com/_/ubuntu/) Linux based Docker image and an [Alpine](https://hub.docker.com/_/alpine/) Linux based Docker image for Micro-GW base image.
+
+## Prerequisites
+
+* [Docker](https://www.docker.com/get-docker) v17.09.0 or above
+
+## How to build an image
+
+##### 1. Navigate to mg directory in ubuntu or alpine directories based on the preference.
+##### 2. Build the Docker image using the following command.
+
+```docker build --no-cache=true -t wso2/wso2micro-gw:3.2.0 .```
+
+> By default, the Docker image will prepackage the General Availability (GA) release version of the relevant WSO2 product.
+
+NOTE : Please replace the '${MGW_VERSION}' with the relevant microgateway version. For ex: 3.2.0
+
+## Docker command usage references
+
+* [Docker build command reference](https://docs.docker.com/engine/reference/commandline/build/)
+* [Docker run command reference](https://docs.docker.com/engine/reference/run/)
+* [Dockerfile reference](https://docs.docker.com/engine/reference/builder/)
