+
+Singularity is an experimental container solution that is an HPC-friendly alternative to Docker. For many reasons, `singularity` is not a drop-in replacement for Docker. Many applications require modification to fully run with `singularity`. This alternative is provided on a best-effort basis. If issues are encountered, please open an issue on this repository with details and the maintainers will try to provide support as possible.

 `-W <dir>` when executing via Singularity to redirect temp files to a
 larger directory `<dir>`.
 
+Note: By default, `singularity` makes many host resources available inside the container. This is in contrast with Docker's native isolation. This also tends to cause conflicts and errors when running Docker-based workflows. Therefore we recommend always using the `--containall` option to Singularity.

+## WDL workflow
+
+XenoCP includes a [WDL](https://github.com/openwdl/wdl) workflow implementation. This can be run locally or on a supported HPC system. It can also use Docker or Singularity for containerization.
+
+### WDL reference files
+
+As of v1.2, WDL does not support directory inputs. Therefore the reference files provided to the WDL workflow must be compressed (`.tar.gz`) before running. The compressed reference files can be downloaded from [Zenodo](https://zenodo.org/uploads/10162103).
+
+### Running WDL
+
+To run the WDL workflow, you will need a WDL engine. We suggest [miniwdl](https://github.com/chanzuckerberg/miniwdl), though the [Cromwell](https://github.com/broadinstitute/cromwell/) engine should work, but is untested with XenoCP.
+
+After acquiring the reference files for your chosen aligner, you can run the sample data through the WDL workflow with the following command.
+
+```
+miniwdl run https://raw.githubusercontent.com/stjude/XenoCP/main/wdl/workflows/xenocp.wdl input_bam=https://github.com/stjude/XenoCP/raw/main/sample_data/input_data/SJRB001_X.subset.bam input_bai=https://github.com/stjude/XenoCP/raw/main/sample_data/input_data/SJRB001_X.subset.bam.bai reference_tar_gz=MGSCv37_bwa.tar.gz aligner='bwa aln'
+```
+
+This will run all of the steps on the local machine with Docker. The WDL runner `miniwdl` supports alternative execution modes, such as the [Singularity](https://miniwdl.readthedocs.io/en/latest/runner_backends.html#singularity-beta) container engine, [Slurm](https://github.com/miniwdl-ext/miniwdl-slurm) for batch systems, and [LSF](https://github.com/adthrasher/miniwdl-lsf) for batch systems. Alternative execution modes can be specified using `miniwdl`'s [configuration system](https://miniwdl.readthedocs.io/en/latest/runner_reference.html#configuration).
