+### "Reverse" flamegraphs
+
+Sometimes it makes sense to to have functions at the bottom and their callers above them. This mode is called "reverse" flamegraph. You can make such graphs with `stackcollapse-ghc` (the real work is done by the `flamegraph` script)
+
+```bash
+stackcollapse-ghc prof_file | flamegraph.pl --reverse --title 'Reverse' --countname ticks > path_to_svg
+```
