 ## What this workflow does for you
 
-With this workflow you can screen and clean your Illumina, Nanopore or any FASTA-formated sequence date. The results are the clean sequences and the sequences identified as contaminated.
+With this workflow you can screen and clean your Illumina, Nanopore or any FASTA-formated sequence data. The results are the clean sequences and the sequences identified as contaminated.
 Per default [minimap2](https://github.com/lh3/minimap2) is used for aligning your sequences to reference sequences but I recommend using `bbduk`, part of [BBTools](https://github.com/BioInfoTools/BBMap), to clean short-read data (_--bbduk_).
 
 You can simply specify provided hosts and controls for the cleanup or use your own FASTA files. The reads are then mapped against the specified host, control and user defined FASTA files. All reads that map are considered as contamination. In case of Illumina paired-end reads, both mates need to be aligned.

+## Results
+
+Running the pipeline will create a directory called `results/` in the current directory with some or all of the following directories and files (plus additional failes for indices, ...):
+
+```text
+results/
+├── clean/
+│   └── <sample_name>.fastq.gz

+```
+
+The most important files you are likely interested in are `results/clean/<sample_name>.fastq.gz`, which are the "cleaned" reads. These are the input reads that *do not* map to the host, control, own fasta or rRNA files (or the subset of these that you provided), plus those reads that map to the "keep" sequence if you used the `--keep` option. Any files that were removed from your input fasta file are placed in `results/removed/<sample_name>.fastq.gz`.
+
+For debugging purposes we also provide various intermediate results in the `intermediate/` folder.
