+## Getting Started
+
+Sming supports multiple architectures and has a [plethora of features](https://sming.readthedocs.io/en/latest/index.html#summary).
+Choose the architecture of your choice to [install the needed development software](https://sming.readthedocs.io/en/latest/getting-started).
+
+You can also try Sming without installing anything locally. We have an [interactive tutorial](https://www.katacoda.com/slaff/scenarios/sming-host-emulator) that can be run directly from your browser.

-## Summary
-
-* Superb performance and memory usage (Sming compiles to native firmware!).
-* Fast and user friendly development.
-* Simple yet powerful hardware API wrappers.
-* Compatible with standard [Arduino Libraries](https://sming.readthedocs.io/en/latest/libraries.html) - use any popular hardware in few lines of code.
-* Built-in file system: [spiffs](https://github.com/pellepl/spiffs).
-* Built-in powerful wireless modules.
-* Powerful asynchronous (async) network stack.
-    * Async TCP and UDP stack based on [LWIP](http://savannah.nongnu.org/projects/lwip/).
-    * With clients supporting: HTTP, MQTT, WebSockets and SMTP.
-    * And servers for: DNS, FTP, HTTP(+ WebSockets), Telnet.
-    * With [SSL support](https://sming.readthedocs.io/en/latest/_inc/Sming/Components/ssl/index.html) for all network clients and servers. Based on [axTLS](http://axtls.sourceforge.net/) and [BearSSL](https://www.bearssl.org/).
-    * Over-The-Air(OTA) firmware upgrades via HTTP(S) and MQTT(S).
-* ESP8266 specific features.
-    * Integrated boot loader [rboot](https://sming.readthedocs.io/en/latest/_inc/Sming/Components/rboot/index.html) with support for 1MB ROMs, OTA firmware updating and ROM switching.
-    * [Crash handlers](https://sming.readthedocs.io/en/latest/information/debugging.html) for analyzing/handling system restarts due to fatal errors or WDT resets.
-    * [PWM support](https://sming.readthedocs.io/en/latest/_inc/Sming/Arch/Esp8266/Components/driver/index.html) based on [Stefan Bruens PWM](https://github.com/StefanBruens/ESP8266_new_pwm.git).
-    * Optional [custom heap allocation](https://sming.readthedocs.io/en/latest/_inc/Sming/Arch/Esp8266/Components/heap/index.html) based on [Umm Malloc](https://github.com/rhempel/umm_malloc.git).
-    * Based on Espressif NONOS SDK. Officially suppored NON SDK version is >= 3.0.1.
-    * Support for a [thin No-Wifi-SDK](https://sming.readthedocs.io/en/latest/_inc/Sming/Arch/Esp8266/Components/esp_no_wifi/index.html). Helpful when a project does not require WiFi (or networking) and reduces code size and memory usage signficantly.
-* Linux/Windows features
-    * Sming has a [host emulator](https://sming.readthedocs.io/en/latest/arch/host/index.html) that allows libraries and sample applications to be compiled on a Linux/Windows host system and be tested before uploading them to an actual microcontroller.
