+## Installing on PlatformIO
+1. Use espressif32 platform at version 5.2.0
+2. Turn on C++17 support for, by setting `build_unflags=-std=gnu++11` and `build_flags=-std=gnu++17`.
+3. Add this library: `lib_deps=https://github.com/jakubdybczak/esp32-arduino-matter.git`
+4. Choose larger partition scheme, for example `board_build.partitions=min_spiffs.csv`
+5. Run example sketch

 ## Example usage
 Please look at [examples](https://github.com/jakubdybczak/esp32-arduino-matter/tree/master/examples). You can test integration with Android and Matter controller by downloading compiled [CHIPTool](https://drive.google.com/drive/folders/1NXqfbRzBQRWCH4VWJQwQSO6KKYeIH7VK) for Android.
 
 ## Limitations
-* Library only works on base ESP32 (no support for ESP32-S2 and other variants).
+* Library only works on base ESP32 (with experimental support for ESP32-S3, ESP32-C3).
 * There is no possibility to change vendor/product ID as this value is pre-compiled.
 * There is no known possibility to change setup PIN.
 * This library comes with precompiled NimBLE, because default Bluedroid shipped with arduino-esp32 takes too much RAM memory.
