 # Haploid variant calling for whole genome sequencing paired end data
 
+This workflow uses Illumina or Element read data to discover variants (short nucleotide polymorphisms, SNPs, and small indels) in haploid genomes with multiple genomic sequences (contigs, scaffolds, or chromosomes).
+
 ## Inputs dataset
 
 - The workflow needs a list of paired end fastq files
 - A GTF containtaing the Gene annotation for the selected haploid genome
 - A fasta file for the haploid genome to call variants against
 
+## Outputs
+
+- Tab-delimited summary of annotated variants
+- Report summarizing the quality of input data and mapping results
+
 ## Processing
 
 - The workflow will remove adapters using fastp
