 The idea behind this product is clear - I want to create something simple that would help to solve this difficult problem.
 Ideally, with <em>one click</em> or <em>a command</em> and with a possibility to integrate it into a pipeline if needed. Inspired by <em>dependency-check</em> architecture and simplicity plus taking in mind that <em>developers just love mapping</em> everything in code, I've created <strong>"TicTaaC"</strong>, which means <em>"Threat modeling-as-a-Code in a Tick"</em>
 
+## Usage
+All the tool is needed is a <strong>data flow code file</strong> described in the <em>yml-like format</em> specially designed for this.<br>
+<strong>The examples</strong> of these files with verbose comments describing every aspect may be found [here](https://github.com/rusakovichma/TicTaaC/tree/master/expl). <br>
 
+### Command Line
+More detailed instructions can be found on the
+[github wiki](https://github.com/rusakovichma/TicTaaC/wiki).
+The latest CLI can be downloaded from github in the [releases section](https://github.com/rusakovichma/TicTaaC/releases). <br>
+On *nix
+```
+$ ./bin/tic-taac.sh -h
+$ ./bin/tic-taac.sh --out . --threatModel [path to threat model file]
+```
+On Windows
+```
+> .\bin\tic-taac.bat -h
+> .\bin\tic-taac.bat --out . --threatModel [path to threat model file]
+```
