Add ESP32-S3 example

README.md

@@ -10,8 +10,15 @@ This should work together with `esp-wifi`. It currently won't work without. Howe
 
 See the examples for how to use it. A key thing is to enable the feature `big-heap` in esp-wifi since more heap memory is needed to get this working.
 
+In general this is heavy in terms of heap memory used and code size. If you can, you should prefer using something like `embedded-tls`.
+
 For now it's missing advanced configuration options which will be added step-by-step.
 
+Currently this won't work on ESP32-S2 - getting it to work will require tweaking the memory usage a lot!
+
+The examples use one hard-coded address of `www.google.com` which might not always work.
+Also the examples include hard-coded certificates which will expire some day.
