+## CanBoot Deployer
+
+The CanBoot deployer allows a user to overwrite their existing bootloader
+with CanBoot, allowing modification and updates without a programmer.  It
+is *strongly* recommended that an alternate recovery (programmer, DFU, etc)
+method is available in the event that something goes wrong during deployment.
+If coming from a stock bootloader it is also recommended that the user create
+a backup before proceeding.
+
+To build the deployer set the `Build CanBoot deployment application` option
+in the menuconfig to your existing bootloader offset.  The additional settings
+apply to the CanBoot binary, configure them just as you would without the
+deployer.  Save your settings and build with `make`.
+
+This will result in an additional binary in the `out` folder, `deployer.bin`.
+Flash `deployer.bin` with your existing bootloader (SD Card, HID, an older
+version of CanBoot, etc).  Once complete, the deployer should reset the
+device and enter CanBoot.  Now you are ready to use CanBoot to flash an
+application, such as Klipper.
