+# ALT v2
+
+The Drop ALT v2 is a 65% mechanical keyboard featuring dual USB-C connectors, an integrated Hi-Speed USB 2.0 hub, and fully customizable RGB backlighting and underlighting.
+
+* Keyboard Maintainer: [zvecr](https://github.com/zvecr)
+* Hardware Availability: [Drop ALT Mechanical Keyboard](https://drop.com/buy/drop-alt-mechanical-keyboard)
+
+Make example for this keyboard (after setting up your build environment):
+
+ make drop/alt/v2:default
+
+Flashing example for this keyboard:
+
+ make drop/alt/v2: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 key at (0,0) in the matrix (usually the top left key or Escape) and plug in the keyboard
+* **Physical reset button**: Quickly double tap the button located under the spacebar
+* **Keycode in layout**: Press the key mapped to `QK_BOOT` if it is available
