 directory.
 
-## Example pipeline
+## Example pipelines
 
 The examples directory shows a simple pipeline in the call.nix and default.nix
 files. You can build it with `nix-build` in the examples directory. The result
 will be linked to ./result, which in this example case is an empty VCF file.
 
+There is another tumour-normal pipeline calling example consisting of `tnpair`
+and `tnpair.nix`. In this case, the shell script tnpair accepts a reference and
+two fastq files to run the pipeline defined in `tnpair.nix` on.
