 assemblers. It also introduces a new graph binning algorithm and achieves
 the best haplotype-resolved assembly given trio data.
 
+## Why Hifiasm?
+
+* Hifiasm delivers high-quality assemblies. It tends to generate longer contigs
+  and resolve more segmental duplications than other assemblers.
+
+* Given sequence reads from the parents, hifiasm can produce overall the best
+  haplotype-resolved assembly so far. It is the assembler of choice by the
+  [Human Pangenome Project][hpp] for the first batch of samples.
+
+* Hifiasm can purge duplications between haplotigs without relying on
+  third-party tools such as purge\_dups. Hifiasm does not need polishing tools
+  like pilon or racon, either. This simplifies the assembly pipeline and saves
+  running time.
+
+* Hifiasm is fast. It can assemble a human genome in half a day and assemble a
+  ~30Gb redwood genome in three days. No genome is too large for hifiasm.
+
+* Hifiasm is trivial to install and easy to use. It does not required python,
+  R or C++11 compilers and can be compiled into a single executable. The
+  default setting works well with a variety of genomes.
