+You are likely rendering too many pages at once, causing the memory in the
+plugin to fill up too much. Try calling the `muchpdf` function several times
+with different ranges instead:
+```typ
+#let end = 50 // The number of pages you want to output.
+#let step = 10 // Choose this value depending on the complexity of the document.
+#for i in range(0, end, step: step) {
+  muchpdf(data, pages: (start: i, end: calc.min(end, i + step - 1)))
+}
+```
