 ========================
 Pyleri is an easy-to-use parser created for [SiriDB](http://siridb.net/). We first used [lrparsing](http://lrparsing.sourceforge.net/doc/html/) and wrote [jsleri](https://github.com/cesbit/jsleri) for auto-completion and suggestions in our web console. Later we found small issues within the `lrparsing` module and also had difficulties keeping the language the same in all projects. That is when we decided to create Pyleri which can export a created grammar to JavaScript, C, Python, Go and Java.
 
+Gabriele Tomassetti [wrote a tutorial](https://tomassetti.me/pyleri-tutorial/) about the pyleri library.
