+ShellCheck is installed by default on the `ubuntu-latest` host in Azure Pipelines. To see all installed software, consult the [Azure documentation](https://docs.microsoft.com/en-us/azure/devops/pipelines/agents/hosted?view=azure-devops#use-a-microsoft-hosted-agent).
+
+
+## Caveats
+
+Trying to run ShellCheck as usual within the pipeline will produce an error:
+
+```console
+$ shellcheck myscripts/*.sh
+myscripts/*.sh: myscripts/*.sh: openBinaryFile: does not exist (No such file or directory)
+```
+
+The recommended approach is to use `find` to search the files and pass a list of those to ShellCheck:
+```console
+$ shellcheck $(find $(pwd)/myscripts/ -name "*.sh")
+```
+
+
+## Example Pipeline
+
+Copy the following yaml to run ShellCheck in Azure Pipelines against all *.sh files in the current directory:
+
+```yaml
+trigger:
+- master
+
+jobs:
+- job: shellcheck
+  displayName: ShellCheck
+  pool:
+    vmImage: 'ubuntu-latest'
+
+  steps:
+  - script: shellcheck $(find $(pwd) -name "*.sh")
+    displayName: 'Running ShellCheck'
+```
