+# Docker Quick Start
+
+This project includes a Docker workflow that will allow you to build a new firmware for your keyboard very easily without major changes to your primary operating system. This also ensures that when you clone the project and perform a build, you have the exact same environment as anyone else and the QMK build infrastructure. This makes it much easier for people to help you troubleshoot any issues you encounter.
+
+## Requirements
+
+The main prerequisite is a working `docker` install.
+* [Docker CE](https://docs.docker.com/install/#supported-platforms)
+
+## Usage
+
+Acquire a local copy of the QMK's repository (including submodules):
+
+```bash
+git clone --recurse-submodules https://github.com/qmk/qmk_firmware.git
+cd qmk_firmware
+```
+
+Run the following command to build a keymap:
+```bash
+util/docker_build.sh <keyboard>:<keymap>
+# For example: util/docker_build.sh planck/rev6:default
+```
+
+This will compile the desired keyboard/keymap and leave the resulting `.hex` or `.bin` file in the QMK directory for you to flash. If `:keymap` is omitted, all keymaps are used. Note that the parameter format is the same as when building with `make`.
+
+There is also support for building _and_ flashing the keyboard straight from Docker by specifying the `target` as well:
+
+```bash
+util/docker_build.sh keyboard:keymap:target
+# For example: util/docker_build.sh planck/rev6:default:flash
+```
+
+You can also start the script without any parameters, in which case it will ask you to input the build parameters one by one, which you may find easier to use:
+
+```bash
+util/docker_build.sh
+# Reads parameters as input (leave blank for all keyboards/keymaps)
+```
+
+## FAQ
+
+### Why can't I flash on Windows/macOS
+
+On Windows and macOS, it requires [Docker Machine](http://gw.tnode.com/docker/docker-machine-with-usb-support-on-windows-macos/) to be running. This is tedious to set up, so it's not recommended; use [QMK Toolbox](https://github.com/qmk/qmk_toolbox) instead.
+
+!> Docker for Windows requires [Hyper-V](https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/quick-start/enable-hyper-v) to be enabled. This means that it cannot work on versions of Windows which don't have Hyper-V, such as Windows 7, Windows 8 and **Windows 10 Home**.

+Now that you've built a custom firmware file you'll want to flash your keyboard.
+
+## Put Your Keyboard into DFU (Bootloader) Mode
+
+In order to flash your custom firmware you must first put your keyboard into a special flashing mode. While it is in this mode you will not be able to type or otherwise use your keyboard. It is very important that you do not unplug the keyboard or otherwise interrupt the flashing process while the firmware is being written.
+
+Different keyboards have different ways to enter this special mode. If your PCB currently runs QMK, TMK, or PS2AVRGB (Bootmapper Client) and you have not been given specific instructions, try the following, in order:
+
+* Hold down both shift keys and press `Pause`
+* Hold down both shift keys and press `B`
+* Unplug your keyboard, hold down the Spacebar and `B` at the same time, plug in your keyboard and wait a second before releasing the keys
+* Unplug your keyboard, hold down the top or bottom left key (usually Escape or Left Control) and plug in your keyboard
+* Press the physical `RESET` button, usually located on the underside of the PCB
+* Locate header pins on the PCB labeled `RESET` and `GND`, and short them together while plugging your PCB in
+
+If you've attempted all of the above to no avail, and the main chip on the board says `STM32` on it, this may be a bit more complicated. Generally your best bet is to ask on [Discord](https://discord.gg/Uq7gcHh) for assistance. It's likely some photos of the board will be asked for -- if you can get them ready beforehand it'll help move things along!
+
+Otherwise, you should see a message in yellow, similar to this in QMK Toolbox:
+
+```
+*** DFU device connected: Atmel Corp. ATmega32U4 (03EB:2FF4:0000)
+```
+
+and this bootloader device will also be present in Device Manager, System Information.app, or `lsusb`.

+# 'serial' Driver
+This driver powers the [Split Keyboard](feature_split_keyboard.md) feature.
+
+!> Serial in this context should be read as **sending information one bit at a time**, rather than implementing UART/USART/RS485/RS232 standards.
+
+All drivers in this category have the following characteristics:
+* Provides data and signaling over a single conductor
+* Limited to single master, single slave
+
+## Supported Driver Types
+
+|                   | AVR                | ARM                |
+|-------------------|--------------------|--------------------|
+| bit bang          | :heavy_check_mark: | Soon™              |
+| USART Half-duplex |                    | :heavy_check_mark: |
+
+## Driver configuration
+
+### Bitbang
+Default driver, the absence of configuration assumes this driver. To configure it, add this to your rules.mk:
+
+```make
+SERIAL_DRIVER = bitbang
+```
+
+Configure the driver via your config.h:
+```c
+#define SOFT_SERIAL_PIN D0  // or D1, D2, D3, E6
+#define SELECT_SOFT_SERIAL_SPEED 1 // or 0, 2, 3, 4, 5
+                                   //  0: about 189kbps (Experimental only)
+                                   //  1: about 137kbps (default)
+                                   //  2: about 75kbps
+                                   //  3: about 39kbps
+                                   //  4: about 26kbps
+                                   //  5: about 20kbps
+```
+
+### USART Half-duplex
+Targeting STM32 boards where communication is offloaded to a USART hardware device. The advantage is that this provides fast and accurate timings. `SOFT_SERIAL_PIN` for this driver is the configured USART TX pin. **The TX pin must have appropriate pull-up resistors**. To configure it, add this to your rules.mk:
+
+```make
+SERIAL_DRIVER = usart
+```
+
+Configure the hardware via your config.h:
+```c
+#define SOFT_SERIAL_PIN B6  // USART TX pin
+#define SELECT_SOFT_SERIAL_SPEED 1 // or 0, 2, 3, 4, 5
+                                   //  0: about 460800 baud
+                                   //  1: about 230400 baud (default)
+                                   //  2: about 115200 baud
+                                   //  3: about 57600 baud
+                                   //  4: about 38400 baud
+                                   //  5: about 19200 baud
+#define SERIAL_USART_DRIVER SD1 // USART driver of TX pin. default: SD1
+#define SERIAL_USART_TX_PAL_MODE 7 // Pin "alternate function", see the respective datasheet for the appropriate values for your MCU. default: 7
+```
+

-# gherkin super micro edition
+# The 25% SuperMicro keyboard
+## A full featured keymap on Gherkin compatible with a pure "Alpha 26" layout
 
-With this configuration the "28" layout first experimented on the plank-like jj40 is being ported to a more proper board, leaving just two keys not used.
+With this configuration the "SuperMicro" layout first experimented on the plank-like jj40 is being ported to a more proper board, and with the last changes, this layout has been made compatible also to a "26 keys" one. So you can now choose to leave all 30 keys on the keyboard, or remove the two on the bottom line corners to have the "old" and comfortable 28 keys layout, or remove also space and enter to have the simplest "pure alpha" one! And even the intermediate 27 keys one is an interesting compatible option!
 
-For more information please have a look at https://github.com/stevexyz/qmk_firmware/blob/master/keyboards/jj40/keymaps/stevexyz/readme.md 
+This keymap is for a generic usage, trying to avoid as much gimmick as possible (considering the number of keys) and retain muscle memory from people used to the standard Qwerty 104 keys one. Functions and numbers (with related symbols) are on the first row as expected; other examples of design coherency include the symbols on the central row laid out in the same order as you'll find on a standard full keyboard, and the cursor movement aligned to the common unix vi standard ("hjkl", and for symmetry "sdfg" for home/pgdn/pgup/end). I've personally used this layout for months on my home PC in parallel to my portable work PC.
 
-The image below explain the main layers. In addition to them with q, w and e there are three specific dedicated layers for cursors/mouse, numpad and media.
-![layers](https://raw.githubusercontent.com/stevexyz/qmk_firmware/master/keyboards/40percentclub/gherkin/keymaps/stevexyz/layers.jpeg)
+Relying just on the alphabetic keys this layout can be also very easily ported and tested on any qmk supported keyboard (ok, butterstick excluded).
+
+The image below explains the main layers activated respectively with F, N or both modifiers pressed together. In addition to them there are available 5 layers that can be personalized as needed or completely removed without losing any functionality; three of them are currently setup in the default keymap for cursors/mouse, numpad and media (activated with q, w and e respectively).
