+# Minify TF
+
+This is a simple script to output minify the Terraform CLI output. The script is **only** able to plan (or plan a destruction) because you should always check the real plan before applying.
+
+## Usage
+
+Normal planning:
+
+```bash
+minify_tf plan # Plan the Creation/Update of the infrastructure
+minify_tf destroy # Plan the Destruction of the infrastructure
+```
+
+Regenerate the last plan:
+
+```bash
+minify_tf regen # Regenerate the last plan with minimal output
+minify_tf regenfull # Regenerate the last plan with full output
+```
+
+Other commands:
+
+```bash
+minify_tf about # Show the about message
+minify_tf version # Show the version of the script
+```
+
+## Installation
+
+There are two ways of installing this script:
+
+1. Put the script in your `$PATH` (e.g. `/usr/local/bin`)
+2. Use Homebrew (or Linuxbrew) to install it:
+
+```bash
+brew tap k3y0708/tap
+brew install minify_tf
+```
