 ## Disclaimer
 
-Project Trellis is currently **highly** experimental. Do not use it for anything mission critical like avionics, nuclear power or automatic cat feeders!
+Project Trellis is currently experimental. Do not use it for anything mission critical like avionics, nuclear power or automatic cat feeders!
 Although I have not managed to destroy any FPGAs, there is a non-zero chance that the tools could produce a bitstream that destroys or degrades the FPGA. Do not
 use with a development board that you cannot afford to lose!

-## Notes
 
-In all cases there are a handful of constant bits (that remain the same in all ECP5 designs), whose detailed function
-is unknown - even if the low-level purpose, such as tying an internal signal low, is known. This is why there is a
-"_empty.config" file in all examples. These files are also located in the `misc/basecfgs` folder. If you need to
-change any of the examples to a different ECP5 device, you will also need to pick the appropriate base config.
-
-IO constraints are currently specified as attributes on `TRELLIS_IO` primitives, reading IO constraint files
-is not yet implemented.
