 Without the display, it functions identical to the original.
 The original "usermod_v2_auto_save" will not work with the display just yet.

 ## Installation
 
-Please refer to the original `usermod_v2_rotary_encoder_ui` readme for the main instructions.<br/>
-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.
+Copy the example `platformio_override.sample.ini` to the root directory of your particular build and rename it to `platformio_override.ini`.
 
+To activate this alternative usermod, add `#define USE_ALT_DISPlAY` (NOTE: CASE SENSITIVE) to the `usermods_list.cpp` file, or add `-D USE_ALT_DISPlAY` to your `platformio_override.ini` file
+
+### Define Your Options
+
+* `USERMOD_ROTARY_ENCODER_UI`       - define this to have this user mod included wled00\usermods_list.cpp
+* `USERMOD_FOUR_LINE_DISPLAY`       - define this to have this the Four Line Display mod included wled00\usermods_list.cpp
+                                        also tells this usermod that the display is available
+                                        (see the Four Line Display usermod `readme.md` for more details)
+* `USE_ALT_DISPlAY`                 - Mandatory to use Four Line Display
+* `ENCODER_DT_PIN`                  - defaults to 18
+* `ENCODER_CLK_PIN`                 - defaults to 5
+* `ENCODER_SW_PIN`                  - defaults to 19
+* `USERMOD_ROTARY_ENCODER_GPIO`     - GPIO functionality:
+                                        `INPUT_PULLUP` to use internal pull-up
+                                        `INPUT` to use pull-up on the PCB
