+Workflow for developing would be the following:

+```sh
+# Bootc root folder:
+yarn watch
+
+# In a separate terminal in the Podman Desktop folder:
+yarn watch --extension-folder ../podman-desktop-extension-bootc/packages/backend

+# Formatting, linting and typecheck
+yarn format:fix
+yarn lint:fix
+yarn typecheck
