 And do the following :
 
 - Clone or download this repository.
+- Revert changes from https://github.com/SpinalHDL/SpinalTemplateSbt/commit/173bbb9bb8cbf70087339104f6ebced9321908dd
 - Run ```sbt eclipse``` in the ```SpinalTemplateSbt``` directory.
 - Import the eclipse project from eclipse.
 - In the project (eclipse project GUI), right click on src/main/scala/mylib/MyTopLevel.scala, right click on MyTopLevelVerilog, and select run it
 
 Normally, this must generate output file ```MyTopLevel.v```.
 
+## Mill Support (Experimental)
+
+This Spinal Base Project contains support for the [Mill build tool](https://com-lihaoyi.github.io/mill).
+
+The prerequisites are the same as for using SBT, except for sbt itself. Additionally, the ```mill``` executable needs to be installed on the path. Download it to ```/usr/local/bin/mill``` or ```~/bin/mill``` according to the [installation instructions](https://com-lihaoyi.github.io/mill/mill/Intro_to_Mill.html#_installation).
+
+You can clone and use this repository in the following way.
+
+```sh
+git clone https://github.com/SpinalHDL/SpinalTemplateSbt.git
+```
+
+Open a terminal in the root of it and execute your favorite mill command. At the first execution, the process could take some seconds
+
+```sh
+cd SpinalTemplateSbt
+
+//If you want to generate the Verilog of your design
+mill mylib.runMain mylib.MyTopLevelVerilog
+
+//If you want to generate the VHDL of your design
+mill mylib.runMain mylib.MyTopLevelVhdl
+
+//If you want to run the scala written testbench
+mill mylib.runMain mylib.MyTopLevelSim
+```
+
+The top level spinal code is defined into src\main\scala\mylib
