SNDL is a Google Chrome add-on developed by HAOUARI Noureddine that aims to simplify the process of accessing scientific articles. With this add-on, users only need to enter their SNDL login information once, and then they can easily open any scientific article by clicking on the add-on's link.

To use SNDL, simply click on the add-on icon and then select "options" to enter your login information. Save this information for future use. From then on, whenever you come across a scientific article, you can simply click on the add-on icon and it will open the article directly in SNDL.

Please note that SNDL only supports specific fields, so only articles within those fields can be accessed using this add-on.
