-
-1. turn the radio on while holding PTT and the first side button 
-2. go to BATCAL option and adjust the voltage with UP/DOWN buttons
-3. confirm the setting, calibration will be saved to EEPROM

+   * long press buttons functions replicating F+ action
+   * fast scanning
+   * channel name editing in the menu
+   * channel name + frequency display option
+   * shortcut for scan-list assignment (long press `5 NOAA`)
+   * scan-list toggle (long press `* Scan` while scanning)
+   * configurable button function selectable from menu
+   * battery percentage/voltage on status bar, selectable from menu
+   * longer backlight times
+   * mic bar
+   * RSSI s-meter
+   * more frequency steps
+   * squelch more sensitive
+* fagci spectrum analyzer (**F+5** to turn on)
+* some other mods introduced by me:
+   * SSB demodulation (adopted from fagci)
+   * backlight dimming
+   * battery voltage calibration from menu
+   * better battery percentage calculation, selectable for 1600mAh or 2200mAh
+   * more configurable button functions
+   * long press MENU as another configurable button
+   * better DCS/CTCSS scanning in the menu (`* SCAN` while in RX DCS/CTCSS menu item)
+   * Piotr022 style s-meter
+   * restore initial freq/channel when scanning stopped with EXIT, remember last found transmission with MENU button
+   * reordered and renamed menu entries
+   * LCD interference crash fix
+   * many others...

-# User customization
+## User customization
 
 You can customize the firmware by enabling/disabling various compile options, this allows
 us to remove certain firmware features in order to make room in the flash for others.
 You'll find the options at the top of "Makefile" ('0' = disable, '1' = enable) ..
 
-```
-ENABLE_CLANG                  := 0     **experimental, builds with clang instead of gcc (LTO will be disabled if you enable this)

-* Long-press 'M' .. Copy selected channel into same VFO, then switch VFO to frequency mode
+## Compiler
-*
-* Long-press '7' .. Toggle selected channel scanlist setting .. if VOX  is disabled in Makefile
-* or
-* Long-press '5' .. Toggle selected channel scanlist setting .. if NOAA is disabled in Makefile
-*
-* Long-press '*' .. Start scanning, then toggles the scanning between scanlists 1, 2 or ALL channels

-# Some changes made from the Quansheng firmware
-
-* Various Quansheng firmware bugs fixed
-* Added new bugs
-* Mic menu includes max gain possible
-* AM RX everywhere (left the TX as is)
-* An attempt to improve the AM RX audio (demodulator getting saturated/overloaded in Quansheng firmware)
-* keypad-5/NOAA button now toggles scanlist-1 on/off for current channel when held down - IF NOAA not used
-* Better backlight times (inc always on)
-* Live DTMF decoder option, though the decoder needs some coeff tuning changes to decode other radios it seems
-* Various menu re-wordings (trying to reduce 'WTH does that mean ?')
-* ..

+## Building
 
-If you have docker installed you can use `compile-with-docker.bat`, the output files are created in `compiled-firmware` folder. This method gives significantly smaller binaries, I've seen differences up to 1kb, so it can fit more functionalities this way. The challange can be (or not) installing the docker itself.
+### Github Codespace build method
 
+This is the least demanding option as you don't have to install enything on your computer. All you need is Github account.
 
-To compile directly in windows:
+1. Go to https://github.com/egzumer/uv-k5-firmware-custom
+1. Click green `Code` button
+1. Change tab from `Local` to `Codespace`
+1. Click green `Create codespace on main` button

+
+5. Open `Makefile`
+1. Edit build options, save `Makefile` changes
+1. Run `./compile-with-docker.sh` in terminal window
+1. Open folder `compiled-firmware`
+1. Right click `firmware.packed.bin`
+1. Click `Download`, now you should have a firmware on your computer that you can proceed to flash on your radio. You can use [online flasher](https://egzumer.github.io/uvtools)
