 ### Variant Calling
 This APP developed for germline and somatic short variant discovery (SNVs + Indels).

-**Germline**
+***Germline***
 * Haplotyper
 
-**Somatic**
+***Somatic***
 * TNseq (TNhaplotyper2)
 * TNscope
 * VarScan
 * TNhaplotyper (This caller is only available in `v0.1.0` as it is too outdated)
 
-***Accepted data***
+**Accepted data**
 * TN matched WES for somatic variant calling
 * TN matched WGS for somatic variant calling
 * Normal-only WES for germline variant calling
