	   Hello and welcome to Homogram!<br><br>
	   
	   Homogram is a light and simple software on premise to share your images.<br><br>
	   
	   Homogram is released under GPLv3 license, it is supplied AS-IS and we do not take any responsibility for its misusage.<br><br>
	   
     The name *Homogram* comes from a prank on the name 'instagram', in fact differently from the latter Homogram gives priorities to homines..<br><br>
     However Homogram doesn't birth as a replacement but just like its alter ego.. :o)<br><br> 
     
	   First step, use the left side panel password and salt fields to create the hash to insert in the config file. Remember to manually set there also the salt value.<br><br>
	   
	   As you are going to run Homogram in the PHP process context, using a limited web server or phpfpm user, you must follow some simple directives for an optimal first setup:<br>
	   <ol>
	   <li>Check the write permissions of your "HGRepo" folder in your web app public path; and set its path in the config file.</li>
	   <li>Check the write permissions of your "data" folder in your web app private path; and set its path in the config file.</li>
	   </ol>
	   
	   <br>	
     
	   Hope you can enjoy it and let us know about any feedback: <a href="mailto:info@homogram.org" style="color:#e6d236;">info@homogram.org</a>
