 ### How to add new symbols:
 
 * Browse [this cheatsheet](https://fontawesome.com/cheatsheet/free/solid) and pick symbols
-* For each symbol, add its hex code (0xf641 for the 'Ad' icon, for example) to the *Range* list (Remember to keep this
-  readme updated with newest range list)
-* Convert this hex value into a UTF-8 code
+* For each symbol, add its hex code (0xf641 for the 'Ad' icon, for example) to the *Range* list (or the symbol list when its simple enough) in the `fonts.json` file
+* * Convert this hex value into a UTF-8 code
   using [this site](http://www.ltg.ed.ac.uk/~richard/utf-8.cgi?input=f185&mode=hex)

 ### Navigation font
 
 `navigtion.ttf` is created with the web app [icomoon](https://icomoon.io/app) by importing the svg files from `src/displayapp/icons/navigation/unique` and generating the font. `lv_font_navi_80.json` is a project file for the site, which you can import to add or remove icons.
 
-This font must be generated with the `lv_font_conv` tool, which has additional options not available in the online converter.

-`lv_font_conv --font navigation.ttf -r '0xe900-0xe929' --size 80 --format lvgl --bpp 2 -o lv_font_navi_80.c`
