 This library provides a [OpenStreetMap](https://www.openstreetmap.org/) (OSM) map fetching and tile caching system for ESP32-based devices.  
 Under the hood it uses [LovyanGFX](https://github.com/lovyan03/LovyanGFX) and [PNGdec](https://github.com/bitbank2/PNGdec) to do the heavy lifting.
 
-A map is composed from downloaded OSM tiles and returned as a LGFX sprite.
-
-Tile fetching and decoding is performed concurrently across both cores on dualcore ESP32 devices.  
-
-This library is **PlatformIO only** due to use of modern C++ features. The Arduino IDE is **not** supported.  
-Use [the latest Arduino ESP32 Core version](https://github.com/pioarduino/platform-espressif32/releases/latest) from [pioarduino](https://github.com/pioarduino/platform-espressif32) to compile this library.

 Downloaded tiles are cached in psram for reuse.
 
 This library should work on any ESP32 type with psram and a LovyanGFX compatible display.  
-OSM tiles are quite large -128kB per tile- so psram is required.
