+# Diffing With Patience
+
+The default diff algorithm used by Git is pretty good, but it can get
+mislead by larger, complex changesets. The result is a noisier, misaligned
+diff output.
+
+If you'd like a diff that is generally a bit cleaner and can afford a little
+slow down (you probably can), you can instead use the `patience` algorithm
+which is described as such:
+
+> Patience Diff, instead, focuses its energy on the low-frequency
+> high-content lines which serve as markers or signatures of important
+> content in the text. It is still an LCS-based diff at its core, but with
+> an important difference, as it only considers the longest common
+> subsequence of the signature lines:
+
+> Find all lines which occur exactly once on both sides, then do longest
+> common subsequence on those lines, matching them up.
+
+You can set this as the default algorithm by adding the following lines to
+your `~/.gitconfig` file:
+
+```
+[diff]
+    algorithm = patience
+```
+
+or it can be set from the command line with:
+
+```bash
+$ git config --global diff.algorithm patience
+```
