+
+* case-insensitive languages are more suitable for beginners, because they don't have to worry about the case of identifiers and keywords
+* there are basically two options you can choose from:
+  * you can either make Langium case-insensitive by configuration
+  * or you can include case-insensitivity only where you need it
+
+## Case-insensitive Langium
+
+* to make Langium case-insensitive, you have to set the `caseInsensitive` option in the `LangiumConfig` object
+
+## Case-insensitivity on demand
+
+* if you want to include case-insensitivity only where you need it, you can use the `i` flag inside of your grammar regexes
+* do not forget to adjust your scoping as well!
