Using anticrux engine with PyChess GUI

[gbtami]

Just a little nitpicking. Now https://github.com/ecrucru/anticrux#procedure-for-pychess say "To start a new game, you should always use the menu "File > New game" because the home screen is unable (at the current time) to start a variant game."

You can start the same dialog as "File > New game" from home screen just clicking on big weather icon button.

That's a good remark. The procedure is updated.

Thanks.
