<p>I want to open the English Auction example. I was looking for it on the playground, but couldn't find it. Where did I go wrong?</p>
<p>First I have checked out the commit with SHA1 hash <em>41149926c108c71831cfe8d244c83b0ee4bf5c8a</em> in <a href="https://github.com/input-output-hk/plutus-apps" rel="nofollow noreferrer">the plutus-apps repo</a>. Then I have build the playground server with <code>nix-build -A plutus-playground.server</code> as was suggested in a hint on the IOHK discord server (no link unfortunately, since not accessible from everywhere). I do not know what this did, but I remember it worked. Then I opened another terminal and inside this same repo I ran <code>nix-shell</code> and then changed directory to the <code>plutus-playground-client</code>. I ran <code>plutus-playground-server</code>, which seemed to have started the server without any mentionable warnings or errors:</p>

I want to open the English Auction example. I was looking for it on the playground, but couldn't find it. Where did I go wrong?
First I have checked out the commit with SHA1 hash 41149926c108c71831cfe8d244c83b0ee4bf5c8a in the plutus-apps repo. Then I have build the playground server with nix-build -A plutus-playground.server as was suggested in a hint on the IOHK discord server (no link unfortunately, since not accessible from everywhere). I do not know what this did, but I remember it worked. Then I opened another terminal and inside this same repo I ran nix-shell and then changed directory to the plutus-playground-client. I ran plutus-playground-server, which seemed to have started the server without any mentionable warnings or errors:

If I remember correctly I then could already see stuff running on the https://localhost:8009 (ignoring the warnings about the self-signed certificate). Anyways I continued following the week01 instructions and opened the plutus-apps once more, executed the nix-shell again and then navigated to the repo of the plutus-pioneer-program, which I had cloned earlier. There I changed directory to code/week01 and
$ cabal update
$ cabal build

the project. However the auction game is not visible anywhere. The plutus playground is visible on https://localhost:8009, but I do not see the auction game. Help anyone?
