+# Default Screenshot Location
+
+By default, Mac saves all screenshots to the desktop. If you'd like
+screenshots to be dumped somewhere else, you have to configure it manually
+from the command line. For instance, if you'd like your screenshots to be
+saved in the `~/screenshots` directory, then enter the following commands:
+
+```bash
+$ mkdir ~/screenshots
+$ defaults write com.apple.screencapture location ~/screenshots
+$ killall SystemUIServer
+```
