+## Pickle/Serialization Support
+You can Serialize your loaded notifications so they can be restored later on:
+```python
+import apprise
+import pickle
+
+# Instantiate our object
+apobj = apprise.Apprise()
+
+# Add our URLs
+apobj.add("json://localhost")
+apobj.add("xml://localhost")
+apobj.add("form://localhost")
+apobj.add("mailto://user:pass@localhost")
+
+# Now serialize our object for any purpose
+serialized = pickle.dumps(apobj)
+
+# Consider even storing it to disk if you wanted:
+with open("myfile.txt", "w") as file:
+    file.write(serialized)
+```
+
+With respect to the above example, we could later (or in another application) reload our object back as it was without having to re-add all the URLs again:
+```python
+# Restore our Apprise Object
+apobj = pickle.loads(serialized)
+
+# Perhaps we previously wrote it to disk, well we can load our data this way as well:
+with open("myfile.txt", "r+") as file:
+   apobj = pickle.loads(file.read())
+```
