+These scripts are primarily meant to support the use of
+[Janky](https://github.com/github/janky). To use them, read the contents of this
+repository into a `script` folder:
+
+```
+$ git remote add objc-build-scripts https://github.com/jspahrsummers/objc-build-scripts.git
+$ git fetch objc-build-scripts
+$ git read-tree --prefix=script/ -u objc-build-scripts/master
+```
+
+Then commit the changes to incorporate the scripts into your own repository's
+history. You can also freely tweak the scripts for your specific project's
+needs.
+
+To bring in upstream changes later:
+
+```
+$ git fetch -p objc-build-scripts
+$ git merge -Xsubtree=script objc-build-scripts/master
+```
