You can use a URL to refer to an external homepage in your document. As known from Word or other text editors, the URL is automatically converted into a clickable link. In order to achieve the same in LaTeX, a suitable package must be imported and the correct command entered. More on this in this tipps + tricks article.  
  How to insert a URL in LaTeX 
  There are two packages with which URLs can be represented in LaTeX. Import either the  url  package with   \usepackage{url}   or the  hyperref  package with   \usepackage{hyperref}   . We recommend the latter - since the  hyperref  package can not only be used to link URLs, but also references to other chapters or figures. Problems with other packages can occur, which is why   \usepackage{hyperref}   the last package in the document should be imported. 
  So enter the command in the preamble of your LaTeX documents   \usepackage{hyperref}   . Then URLs can be   \url{...}   generated in the text with the command . Here is sample code for using URLs: 
 
   \documentclass{article}   
   \usepackage{hyperref} 
 \begin{document}   
   Unsere Internetseite ist auf \url{https://www.heise.de/tipps-tricks/} erreichbar.   
   \end{document}   
  
			
			  If you convert the whole thing into a PDF, you get a clickable URL. By default, the display of URLs with  hyperref is  not really appealing. In order to make links more recognizable, it is advisable to display them in blue. A few settings must be made for this. We show below what you have to set in the options of  hyperref  :  
    \usepackage[ 
 colorlinks=true, 
 urlcolor=blue, 
 linkcolor=green 
 ]{hyperref}   
   The links in the compiled document look like this:
