 # Singularity Builds
 
-Definitions for [Singularity](https://sylabs.io/singularity/) files for software that I want to use, but wasn't already there.

+
+Definition files for building [Nextflow]-compatible [Singularity] container
+images to use in bioinformatics pipelines. Programs get containers in this
+repository if I can't find an up-to-date container that also has Nextflow's
+dependencies installed (usually `bash` and `ps` are the culprits). All of these
+images are available on the [Sylabs Cloud Library] for easy access.
+
+## Get started
+
+1. [Install Singularity]
+2. Enter the container, e.g.
+
+    ```bash
+    singularity shell library://millironx/default/julia:latest
+    ```
+
+3. Execute commands, e.g.
+
+    ```shellsession
+    Singularity> julia
+                   _
+       _       _ _(_)_     |  Documentation: https://docs.julialang.org
+      (_)     | (_) (_)    |
+       _ _   _| |_  __ _   |  Type "?" for help, "]?" for Pkg help.

+
+## Where else to find container images
+
+### State Public Health Bioinformatics (StaPH-B) Dockerfiles
+
+[:globe_with_meridians: Website](https://staph-b.github.io/) -
+[:octocat: GitHub](https://github.com/StaPH-B/docker-builds) -
+[:whale: Docker hub](https://hub.docker.com/u/staphb)
+
+All of these images are tested for Nextflow and Singularity compatability, and
+are updated on a regular basis. I've even contributed to their repository.
+
+### Biocontainers Registry
+
+[:globe_with_meridians: Website](https://biocontainers.pro/) -
+[:octocat: GitHub](https://github.com/BioContainers/containers) -
+[:whale: Docker hub](https://hub.docker.com/u/biocontainers)
+
+Most of these images are already in Singularity format, and there are _a lot_ of
+tools for the picking here.
