 ## Introduction
 
-**nf-core/eager** is a bioinformatics best-practice analysis pipeline for ancient DNA data analysis.
-
-The pipeline uses [Nextflow](https://www.nextflow.io), a bioinformatics workflow tool. It pre-processes raw data from FastQ inputs, aligns the reads and performs extensive quality-control on the results. It comes with docker / singularity containers making installation trivial and results highly reproducible.
-
-### Pipeline steps
-
-* Create reference genome indices (optional)
-    * BWA 
-    * Samtools Index
-    * Sequence Dictionary
-* QC with FastQC
-* AdapterRemoval for read clipping and merging
-* Read mapping with BWA, BWA Mem or CircularMapper
-* Samtools sort, index, stats & conversion to BAM
-* DeDup or MarkDuplicates read deduplication
-* QualiMap BAM QC Checking
-* Preseq Library Complexity Estimation
-* DamageProfiler damage profiling
-* BAM Clipping for UDG+/UDGhalf protocols
-* PMDTools damage filtering / assessment

-### Documentation
+**nf-core/eager** is a bioinformatics best-practice analysis pipeline for NGS 
+sequencing based ancient DNA (aDNA) data analysis.
+
+The pipeline uses [Nextflow](https://www.nextflow.io), a bioinformatics 
+workflow tool. It pre-processes raw data from FASTQ inputs, aligns the reads 
+and performs extensive general NGS and aDNA specific quality-control on the 
+results. It comes with docker, singularity or conda containers making 
+installation trivial and results highly reproducible.
+
+## Pipeline steps
+
+By default the pipeline currently performs the following:
+
+* Create reference genome indices for mapping (`bwa`, `samtools`, and `picard`)
+* Sequencing quality control (`FastQC`)
+* Sequencing adapter removal and for paired end data merging (`AdapterRemoval`)
+* Read mapping to reference using (`bwa aln`, `bwa mem` or `CircularMapper`)
+* Post-mapping processing, statistics and conversion to bam (`samtools`)
+* Ancient DNA C-to-T damage pattern visualisation (`DamageProfiler`)
+* PCR duplicate removal (`DeDup` or `MarkDuplicates`)
+* Post-mapping statistics and BAM quality control (`Qualimap`)
+* Library Complexity Estimation (`preseq`)
+* Overall pipeline statistics summaries (`MultiQC`)
+
+Additional functionality contained by the pipeline currently includes:
+
+* Illumina two-coloured sequencer poly-G tail removal (`fastp`)
+* Automatic conversion of unmapped reads to FASTQ (`samtools`)
+* Damage removal/clipping for UDG+/UDG-half treatment protocols (`BamUtil`)
+* Damage reads extraction and assessment (`PMDTools`)
+
+## Quick Start
+
+1. Install [`nextflow`](docs/installation.md)
+2. Install one of [`docker`](https://docs.docker.com/engine/installation/), [`singularity`](https://www.sylabs.io/guides/3.0/user-guide/) or [`conda`](https://conda.io/miniconda.html)
+3. Download the EAGER pipeline
+
+```bash
+nextflow pull nf-core/eager
+```
+
+4. Set up your job with default parameters
+
+```bash
+nextflow run nf-core -profile <docker/singularity/conda> --reads'*_R{1,2}.fastq.gz' --fasta '<REFERENCE.fasta'
+```
+
+5. See the overview of the run with under `<OUTPUT_DIR>/MultiQC/multiqc_report.html`
+
+Modifications to the default pipeline are easily made using various options
+as described in the documentation.
