+Sparkleshare and dvcs-autosync are tools to automatically commit your
+changes to git and keep them in sync with other repositories. Unlike
+git-annex, they don't store the file content on the side, but directly in
+the git repository. Great for small files, less good for big files.
+
+Here's how to use the [[git-annex assistant|/assistant]] to do the same
+thing, but even better!
+
+----
+
+Let's suppose you're delveloping a video game, written in C. You have
+source code, and some large game assets. You want to ensure the source
+code is stored in git -- that's what git's for! And you want to store
+the game assets in the git annex -- to avod bloating your git repos with
+possibly enormous files, but still version control them.
+
+All you need to do is configure git-annex to treat your C files
+as small files. And treat any file larger than, say, 100kb as a large
+file that is stored in the annex.
+
+	git config annex.largefiles "largerthan=100kb and not (include=*.c or include=*.h)"
+
+Now if you run `git annex add`, it will only add the large files to the
+annex. You can `git add` the small files directly to git.
+
+Better, if you run `git annex assistant`, it will *automatically*
+add the large files to the annex, and store the small files in git.
+It'll notice every time you modify a file, and immediately commit it,
+too. And sync it out to other repositories you configure using `git annex
+webapp`.
+
+----
+
+It's also possible to disable the use of the annex entirely, and just
+have the assistant *always* put every file into git, no matter its size:
+
+	git config annex.largefiles "exclude=*"
