+# Link
+
+The Link is a Sofle58 inspired Ergo Split keyboard from CannonKeys.
+It uses 1.3" SH1107 screens and ALPS EC11 compatible encoders.
+
+* Keyboard Maintainer: [Andrew Kannan](https://github.com/awkannan)
+* Hardware Supported: RP2040
+* Hardware Availability: [CannonKeys](https://cannonkeys.com)
+
+
+Make example for this keyboard (after setting up your build environment):
+
+ make cannonkeys/link:default
+
+Flashing example for this keyboard:
+
+ make cannonkeys/link:default:flash
+
+See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
+
+## Bootloader
+
+Enter the bootloader in 3 ways:
+
+* **Bootmagic reset**: Hold down the top-most and outer-most key in the matrix and plug in the keyboard
+* **Physical reset button**: Hold the "BOOTMODE" button on the back of the PCB and briefly press the "RESET" button on the back of the PCB
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
