+Notes for Conservators
+----------------------
+If you are recording animated GIFs of a game with Octo, be sure to run the output through an optimizer before checking it in- Octo tends to produce very large files. One way to optimize a GIF is to use [gifsicle](https://www.lcdf.org/gifsicle/) like so:
+
+	gifsicle src/mygame/cool.gif --optimize=3 --colors=2 -o src/mygame/cool.gif
+
+Old shared Octo programs used GitHub gists to store their source and metadata. If you have a URL which looks like
+
+	http://johnearnest.github.io/Octo/index.html?gist=bdd2840b9fe5fad7bd5995423ea57a23
+
+You can use the gist ID to view the `options` dictionary and original submission date:
+
+	https://gist.github.com/bdd2840b9fe5fad7bd5995423ea57a23
+
+Octo's newer sharing system uses a custom storage API, and URLs look like this:
+
+	http://johnearnest.github.io/Octo/index.html?key=AcfYNFAu
+
+The `key` can be used to retrieve a JSON file with `options` and other metadata like this:
+
+	https://vectorland.nfshost.com/storage/octo/AcfYNFAu
