+> shellcheck catches rookie mistakes (and old-habits-die-hard mistakes) in bash
+
+### Run shellcheck in your terminal:
+
+```bash
+shellcheck yourscript
+```
+
+<!---
+### Run shellcheck in your editor:
+
+Include running shellcheck in editor?
+
+It's just links to other linters or extensions
+-->
+
+### To use shellcheck in a build or test suite:
+
+Simply include shellcheck in the process.
+
+```bash
+check-scripts:
+    # Fail if any of these files have warnings
+    shellcheck myscripts/*.sh
+```
