 Please look at the examples regarding plurals.
 
+## Handling capitalization
+
+If you use a term at the beginning of a sentence, you might want to capitalize it.
+You can use the `capitalize` argument of `#gls` and `#glspl` to do so,
+or, shorter, call `#Gls` and `#Glspl`.
+
+```typ
+#Gls("ref")
+```
+
+You can also reference the automatically generated labels:
+
+```typ
+@Ref
+@Ref:pl
+```
+
+Please note that these are only generated if the `key` does not start with an uppercase letter.

 ## Overriding the text shown
 
 You can also override the text displayed by setting the `display` argument.
