-## About
-
-`configure-env` will read a `.env.example` or any other similar `.env` file and prompt for values for each variable that has a comment header above it. Afterwards it will generate a `.env` file out of it.
-
-It works as a more user-friendly approach to:
-
-```
-cp .env.example .env
-```
-
-## Installation
-
-You can install the CLI tool via `npm` or another package manager. Ideally install it as a dev dependency instead of global:
-
-```bash
-# Install it as a dev dependency
-npm install configure-env --save-dev
-
-# Afterwards you can use by using:
-node_modules/.bin/configure-env
-
-npx configure-env
-
-# Or inside your package.json scripts section as "configure-env"
-```
-
-## Usage
-
-In a project that contains a `.env.example` file, run:
-
-```bash
-$ npx configure-env --help
-Prompts user for environment variables and generates .env files based on a
-.env.example file
-
-Usage:
-  configure-env.js -o [outputFile] -i [exampleFile]
-
-Options:
-  --help        Show help                                              [boolean]
-  --version     Show version number                                    [boolean]
-  --output, -o  Location of the .env file that should be written
-                                                      [string] [default: ".env"]
-  --input, -i   Location of input .env.example file for prompts
-                                              [string] [default: ".env.example"]
-  --verbose                                           [boolean] [default: false]
-
-Examples:
-  npx configure-env       Reads a .env.example file in the current directory and
-                          creates a .env file
-  configure-env.js | cat  The output can be either written to a file or piped to
-                          another process
