<div class="markdown_content"><p>The libraries in V3 are installed in a Library repository.<br/> To add a library to your project you only have to open the Library Manager (part of your project tree) and add your required library.<br/> If you want to add a library which is not yet available in the Repository you have to install it.<br/> To do this you need to go to Tools-Install Library (or Library Repository with the professional feature set enabled).</p></div>
