+# Assembly polishing with Racon workflow
+
+## Inputs
+
+- Sequencing reads in format: fastq, fastq.gz, fastqsanger.gz or fastqsanger
+- Genome assembly to be polished, in fasta format
+
+## What does the workflow do
+
+- After long reads have been assembled into a genome (contigs), this can be polished with the same long reads. 
+- This workflow uses the tool minimap2 to map the long reads back to the assembly, and then uses Racon to make polishes. 
+- This is repeated a further 3 times. 
+
+In more detail:
+
+- minimap2 : long reads are mapped to assembly => overlaps.paf.
+- overaps, long reads, assembly => Racon => polished assembly 1
+- using polished assembly 1 as input; repeat minimap2 + racon => polished assembly 2
+- using polished assembly 2 as input, repeat minimap2 + racon => polished assembly 3
+- using polished assembly 3 as input, repeat minimap2 + racon => polished assembly 4
+
+## Settings
+
+- Run as-is or change parameters at runtime.
+- For the input at "minimap settings for long reads", enter (map-pb) for PacBio reads, (map-hifi) for PacBio HiFi reads, or (map-ont) for Oxford Nanopore reads.
+
+## Outputs
+
+There is one output: the polished assembly in fasta format.
