@@ -55,27 +55,28 @@ k-mers by their hashcodes. For data of relatively low coverage, you may
 increase this sampling rate by reducing `-S`. This will greatly increase the
 peak memory as a cost, though. Option `-e`, which defaults to 3, specifies the
 minimum read coverage of an edge in the assembly graph. You may adjust this
-option according to the overall sequencing depth, too. For PacBio data,
+option according to the overall sequencing depth, too. Option `-A` also helps
+relatively low coverage data at the cost of performance. For PacBio data,
 `-L5000` often leads to better assemblies emperically, so is recommended.
 Please run `wtdbg2 --help` for a complete list of available options or consult
 [README-ori.md](README-ori.md) for more help.
