-If you use latex, you can automatize references, by creating a bash script with:
-
-    #!/bin/bash
-    pubs export > references.bib
-    latex manuscript.tex
-    bibtex manuscript
-    latex manuscript.tex
+If you use latex, you can automatize references, by running `pubs export > references.bib` each time you update your library, which also fits well as a `makefile` rule.
 
 This ensures that your reference file is always up-to-date; you can cite a paper in your manuscript a soon as you add it in pubs. This means that if you have, for instance, a doi on a webpage, you only need to do:
 
     pubs add -D 10.1007/s00422-012-0514-6
-
-and then add `\cite{Loeb_2012}` in your manuscript. After running the bash script, the citation will correctly appear in your compiled pdf.
