 ## Introduction
 
-**ferlab/postprocessing** is a bioinformatics pipeline that takes GVCFs from several samples to combine, perform joint genotyping, tag low quality variant and annotate a final vcf version.
+**Ferlab-Ste-Justine/Post-processing-Pipeline** is a bioinformatics pipeline designed for family-based analysis of GVCFs from multiple samples. 
+It performs joint genotyping, tags low-quality variants, and optionally annotates the final vcf data using vep and/or prioritize variant using exomiser.

-## Usage
 
-> [!NOTE]
-> If you are new to Nextflow and nf-core, please refer to [this page](https://nf-co.re/docs/usage/installation) on how to set-up Nextflow. Make sure to [test your setup](https://nf-co.re/docs/usage/introduction#how-to-run-a-pipeline) with `-profile test` before running the workflow on actual data.
-
-### Samples
-The workflow will accept sample data separated by commas (CSV format). The path to the sample file must be specified with the "**input**" parameter. The column names are : familyId,sample,sequencingType,file. The sequencing type must be either WES (Whole Exome Sequencing) or WGS (Whole Genome Sequencing).
-
-**sample.csv**
-```csv
-**familyId**,**sample**,**sequencingType**,**file**

+### Workflow subway schema
 
+The full Ferlab workflow is shown in the image below, including the steps applicable prior to this pipeline. The steps relevant to the Ferlab-Ste-Justine/Post-processing-Pipeline correspond to the post-processing block.
+![PostProcessingDiagram](docs/images/ferlab_workflow.png)
 
-> [!NOTE]
-> The sequencing type also determines the type of variant filtering the pipeline will use.
-> 
-> In the case of Whole Genome Sequencing, VQSR (Variant Quality Score Recalibration) is used (preferred method).
-> 
-> In the case of Whole Exome Sequencing, Hard-filtering needs to be used.
+This schema was done using [inkscape](https://inkscape.org/) with the good pratices recommended by the nf-core community. See [nf-core Graphic Design](https://nf-co.re/docs/guidelines/graphic_design).

-### References
-Reference files are necessary at multiple steps of the workflow, notably for joint-genotyping,the variant effect predictor (VEP) and VQSR. 
-Using igenome, we can retrieve the relevant files for the desired version of the human genome.
-Specifically, we specifiy the igenome version with the **genome** parameter. Most likely this value will be *'GRCh38'*
-
 
-Next, we also need broader references, which are contained in a path defined by the **broad** parameter.
+For more details, see [docs/usage.md](docs/usage.md) and [docs/reference_data.md](docs/reference_data.md).
 
-The broad directory must contain the following files:
 
-- The interval list which determines the genomic interval(s) over which we operate: filename of this list must be defined with the **intervalsFile** parameter
-- Highly validated variance ressources currently required by VQSR. ***These are currently hard coded in the pipeline!***
-  - HapMap file : hapmap_3.3.hg38.vcf.gz
-  - 1000G omni2.5 file : 1000G_omni2.5.hg38.vcf.gz
-  - 1000G reference file : 1000G_phase1.snps.high_confidence.hg38.vcf.gz
-  - SNP database : Homo_sapiens_assembly38.dbsnp138.vcf.gz
+### Stub mode and quick tests
 
-
-Finally, the vep cache directory must be specified with **vepCache**, which is usually created by vep itself on first installation.
-Generally, we only need the human files obtainable from https://ftp.ensembl.org/pub/release-112/variation/vep/homo_sapiens_vep_112_GRCh38.tar.gz
+The `-stub` (or `-stub-run`) option can be added to run the "stub" block of processes instead of the "script" block. This can be helpful for testing.
