+[[!meta title="Installing onto a USB stick"]]
+
+Starting from version 0.11, Tails includes a custom USB installer to create
+bootable USB sticks. The advantages of using Tails USB installer are that you
+can:
+
+  - **use the extra space** left on the USB stick,
+  - **setup a persistent storage** to store some of your settings.
+
+But in order to use the USB installer, you need to start Tails from another
+media than the USB you want to install. You can either:
+
+  - **[[Burn a Tails CD|download#index4h1]]** (recommended)
+  - **Use another Tails USB**, for example from a friend
+  - **[[Manually install Tails onto another USB
+    stick|manual_usb_installation]]**, if you can't use a CD
