 This Usermod allows you to monitor the battery level of your battery powered project.
 
-You can see the battery level in the `info modal` right under the `estimated current`. 
+You can see the battery level and voltage in the `info modal`. 
 
 For this to work the positive side of the (18650) battery must be connected to pin `A0` of the d1mini/esp8266 with a 100k ohm resistor (see [Useful Links](#useful-links)).
 
 If you have a esp32 board it is best to connect the positive side of the battery to ADC1 (GPIO32 - GPIO39)

+# I2C 4 Line Display Usermod ALT
+
+Thank you to the authors of the original version of these usermods. It would not have been possible without them!
+"usermod_v2_four_line_display"
+"usermod_v2_rotary_encoder_ui"
+
+The core of these usermods are a copy of the originals. The main changes are done to the FourLineDisplay usermod.
+The display usermod UI has been completely changed.
+
+
+The changes made to the RotaryEncoder usermod were made to support the new UI in the display usermod. 
+Without the display it functions identical to the original.
+The original "usermod_v2_auto_save" will not work with the display just yet.
+
+Press the encoder to cycle through the options:
+    *Brightness
+    *Speed
+    *Intensity
+    *Palette
+    *Effect
+    *Main Color (only if display is used)
+    *Saturation (only if display is used)
+
+Press and hold the encoder to display Network Info
+    if AP is active then it will display AP ssid and Password
+
+Also shows if the timer is enabled
+
+[See the pair of usermods in action](https://www.youtube.com/watch?v=ulZnBt9z3TI)
+
+## Installation
+
+Please refer to the original `usermod_v2_rotary_encoder_ui` readme for the main instructions
+Then to activate this alternative usermod add `#define USE_ALT_DISPlAY` to the `usermods_list.cpp` file,
+                                        or add `-D USE_ALT_DISPlAY` to the original `platformio_override.ini.sample` file
+
+
+### PlatformIO requirements
+
+Note: the Four Line Display usermod requires the libraries `U8g2` and `Wire`.

+# Rotary Encoder UI Usermod ALT
+
+Thank you to the authors of the original version of these usermods. It would not have been possible without them!
+"usermod_v2_four_line_display"
+"usermod_v2_rotary_encoder_ui"
+
+The core of these usermods are a copy of the originals. The main changes are done to the FourLineDisplay usermod.
+The display usermod UI has been completely changed.
+
+
+The changes made to the RotaryEncoder usermod were made to support the new UI in the display usermod. 
+Without the display it functions identical to the original.
+The original "usermod_v2_auto_save" will not work with the display just yet.
+
+Press the encoder to cycle through the options:
+    *Brightness
+    *Speed
+    *Intensity
+    *Palette
+    *Effect
+    *Main Color (only if display is used)
+    *Saturation (only if display is used)
+
+Press and hold the encoder to display Network Info
+    if AP is active then it will display AP ssid and Password
+
+Also shows if the timer is enabled
+
+[See the pair of usermods in action](https://www.youtube.com/watch?v=ulZnBt9z3TI)
+
+## Installation
+
+Please refer to the original `usermod_v2_rotary_encoder_ui` readme for the main instructions
+Then to activate this alternative usermod add `#define USE_ALT_DISPlAY` to the `usermods_list.cpp` file,
+                                        or add `-D USE_ALT_DISPlAY` to the original `platformio_override.ini.sample` file
+
+
+### PlatformIO requirements
+
+Note: the Four Line Display usermod requires the libraries `U8g2` and `Wire`.
+
