+# MiniTMPL
+
+MiniTMPL is a simple, yet powerful tool designed to render text templates using environment variables. It reads a template from `stdin` and outputs the rendered version to `stdout`, making it an excellent tool for generating configuration files, messages, or any text-based content that requires dynamic data insertion.
+
+## Features
+
+- Reads templates from standard input (`stdin`).
+- Renders templates using environment variables.
+- Supports basic template functions provided by Go's `text/template` package.
+
+## Getting Started
+
+To use EnvTemplater, clone this repository or download the latest release to your local machine.
+
+### Prerequisites
+
+Ensure you have Go installed on your system. EnvTemplater requires Go 1.14 or higher.
+
+
+### Building form source
+
+First, clone the repository:
+
+```bash
+git clone https://git.behzadan.ir/p/minitmpl.git
+cd minitmpl
+```
+
+Then, build the program:
+
+```bash
+go build -o minitmpl
+```
+
+## Usage
+
+To use EnvTemplater, simply pipe a template into the program and it will output the rendered version:
+
+```bash
+echo "Hello, {{.USER}}" | ./envtemplater
+```
+
+This will replace `{{.USER}}` with the value of the `USER` environment variable.
+
+## License
