Sign in to our Gmail account. This will give you access to the editing page in Google Sites as well as Search Console, Calendar, Drive, etc.

Select Google Drive 

Once Drive is open click on the Sidney Chess Club button to go to our pages in Google Sites. This seems to be the easiest way to get there at the moment. 

You should have access to some basic tools for editing the site.

 Next we're going to add a position from Lichess to the Puzzles and Studies page. If there's a better way to do this please let me know.

Sign in to our Lichess account: username is sidneychessnuts and password is available on request.

Navigate to Study under Learn.

Select My Studies

Click on the box shown below

Select the nut you want people to crack or position you want to discuss.

Select the share button below the board. Here I take a picture with the Gif button, upload it manually to our site then link it to the Current Chapter URL.

It would be nicer to just use the Embed code but it looks like I've shown below with an annoying blue box.
