 ## SciKGTeX Branch
 This repository also contains a SCIKGTeX branch that uses the `SciKGTeX` package and makes it possible to annotate specific research contributions directly in the LaTeX source code. Interested authors may use the SciKGTeX branch instead of the master branch. The link to the SciKGTeX branch is : [https://git.rwth-aachen.de/inggrid/template/-/tree/SciKGTeX]()

+## SVG images
+If SVG images need to be added, users may uncomment line number 53 in inggrid.cls file, which will facilitate the usage of SVG images. An example for adding an SVG image can be found by uncommenting lines 114-199 of the file main.tex after adding an SVG image to the figures directory. But, users need to be aware that this may work well only in Overleaf and the package and its usage may cause issues in Texlive and other local distributions.

If authors prefer to use SVG images, they should uncomment line number 53 in inggrid.cls file, which will facilitate the usage of SVG images.

An example for adding an SVG image can be found by uncommenting lines 114-199 of the file main.tex after adding an SVG image to the figures directory.

This solution works well in Overleaf/Sharelatex. However, since the svg package requires an Inkscape installation, additional steps are necessary to make the svg package work in Texlive and other local distributions. Interested readers can refer to [link to some website that will give them a basic intro in how to set it up]
