+# Env Replacer
+
+A powerful tool to replace environment variables on template files.
+
+## Why?
+
+I don't like to maintain `bash` scripts, I don't like `gettext` and `envsubst`, so this is a replacement.
+
+
+## Installation
+
+Go to [release page](https://github.com/guumaster/env-replacer/releases) and download the binary you need.
+
+
+## Examples
+
+```bash
+$> env-replacer --path /some-path-to-tpl-files
+```
+
+
+## Usage
+
+    NAME:
+       env-replacer - replace env variables on files
+
+    USAGE:
+       env-replacer [global options] [arguments...]
+
+    VERSION:
+       dev
+
+    AUTHOR:
+       guumaster <guuweb@gmail.com>
+
+    GLOBAL OPTIONS:
+       --path value    path to scan for templates
+
+       --files value   file pattern to search (default: "*.tpl")
+
+       --quiet, -q     hide report (default: false)
+
+       --no-recursive  don't scan path recursively (default: false)
+
+       --no-truncate   don't truncate dst files (default: false)
+
+       --no-error      early quit on error (default: false)
+
+       --no-missing    don't write files with missing variables (default: false)
+
+       --no-empty      fail also with variables (default: false)
+
+       --strict        same as --no-empty and --no-missing combined (default: false)
+
+       --version       print the version (default: false)
