+  title: GA4GH Tool Discovery API
+  description: Proposed API for GA4GH (Global Alliance for Genomics & Health) tool
+    repositories. A tool consists of a set of container images that are paired
+    with a set of documents. Examples of documents include CWL (Common Workflow
+    Language), WDL (Workflow Description Language), NFL (Nextflow), GXFORMAT2
+    (Galaxy) or SMK (Snakemake) that describe how to use those images and a set
+    of specifications for those images (examples are Dockerfiles or Singularity
+    recipes) that describe how to reproduce those images in the future. We use
+    the following terminology, a "container image" describes a container as
+    stored at rest on a filesystem, a "tool" describes one of the triples as
+    described above. In practice, examples of "tools" include CWL
+    CommandLineTools, CWL Workflows, WDL workflows, and Nextflow workflows that
+    reference containers in formats such as Docker or Singularity.
