+# Project billit
+
+One Paragraph of project description goes here
+
+## Getting Started
+
+These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.
+
+## MakeFile
+
+Run build make command with tests
+```bash
+make all
+```
+
+Build the application
+```bash
+make build
+```
+
+Run the application
+```bash
+make run
+```
+Create DB container
+```bash
+make docker-run
+```
+
+Shutdown DB Container
+```bash
+make docker-down
+```
+
+DB Integrations Test:
+```bash
+make itest
+```
+
+Live reload the application:
+```bash
+make watch
+```
+
+Run the test suite:
+```bash
+make test
+```
+
+Clean up binary from the last build:
