+Ergonomics Split Keyboard powered by RP2040.
+
+* Keyboard Maintainer: [ERA](https://github.com/eerraa)
+* Hardware supported: SIRIND Tomak79
+* Hardware availability: [Syryan](https://srind.mysoho.com/)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make era/sirind/tomak79s:default
+
+Flashing example for this keyboard:
+
+    make era/sirind/tomak79s: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-left(ESC, F7)' key and plug in the keyboard.
