 # FPGA tutorial
 
-Here are some materials for my FPGA workshop. The workshop uses the open source
-Icestorm toolchain. The hardware is Icestick and TinyFPGA boards because that's
-what I have, as well as some peripherals like OLED displays.
+See the tutorial at [pwmarcz.github.io/fpga-tutorial/](https://pwmarcz.github.io/fpga-tutorial/),
+or just look into the [docs](docs/) directory.
 
 The code is MIT licensed (see LICENSE) unless otherwise stated in the
 file. Patches welcome!
-
-See also [fpga-experiments](https://github.com/pwmarcz/fpga-experiments) which
-is a very messy sandbox where I try out all this stuff.
-
-This tutorial has the following parts:
-
-## [NandGame](http://nandgame.com/)
-
-Play the excellent [NandGame](http://nandgame.com/). Try to get at least to
-"Data Flip-Flop".
-
-## [Bit operations](bits/)
-
-If you are not familiar with bit operations, learn a bit about them. There
-are some links and exercises in the [bits/](bits/) directory.
-
-## [Verilog basics](verilog/)
-
-Move on to Verilog basics in the [verilog/](verilog/) directory.
-
-## [FPGA](fpga/)
-
-Finally, we get to play with real hardware. See the [fpga/](fpga/) directory.
