+# Docker in Docker for Insecure Registry
+
+This `Dockerfile` is for setting insecure registry easily.
+
+
+## Getting Started
+
+
+### Clone the Repository
+
+Clone this repository using `git clone`
+
+```
+$ git clone https://github.com/Pick1a1username/docker_dind_for_insecure_registry.git

+$ cd docker_dind_for_insecure_registry
+$ docker build -t docker_dind_insecure:0.1 .
+$ docker image ls
+```
+
+### Usage
+
+This image is supposed to be used in Docker Compose.

+Note that the port number of the Docker Registry is expected to be `5000`.
