 Ever wanted to try out someone's project and kept figuring out all the environment variables that were needed ? Or you are just too lazy to document the same in your own project ? Worry not !
 
 This is a simple npm package that will read through the entire codebase (don't worry, only javascript and typescript files) of your project, and create a `.env.example` file with all the environment configurations that are used in the code.
+
+---
+
+## Usage
+
+```bash
+# install the package using
+sudo npm i -g @hackcode/env-example-generator
+
+# run the cli from the project root
+generate-env
+
+# An .env.example file would be created
+```
