+# Compatible with ranger 1.6.*
+#
+# This is a sample plugin that displays "Hello World" in ranger's console after
+# it started.
+
+# We are going to extend the hook "ranger.api.hook_ready", so first we need
+# to import ranger.api:
+import ranger.api
+
+# Save the previously existing hook, because maybe another module already
+# extended that hook and we don't want to lose it:
+old_hook_ready = ranger.api.hook_ready
+
+# Create a replacement for the hook that...
+def hook_ready(fm):
+    # ...does the desired action...
+    fm.notify("Hello World")
+    # ...and calls the saved hook.  If you don't care about the return value,
+    # simply return the return value of the previous hook to be safe.
+    return old_hook_ready(fm)
+
+# Finally, "monkey patch" the existing hook_ready function with our replacement:
+ranger.api.hook_ready = hook_ready
