+### get-repositories-with-copilot-instructions.sh

+
+Usage:
+
+```shell
+./get-repositories-with-copilot-instructions.sh my-org
+```
+
+### get-repositories-without-copilot-instructions.sh
+
+Get repositories that do not have any Copilot custom instruction files (neither `.github/copilot-instructions.md` nor `.github/instructions/`)
+
+Usage:
+
+```shell
+./get-repositories-without-copilot-instructions.sh my-org
+```
