wuffle: Problems installing

Hi, I’ve installed the docker image and I can see a board with the configured columns but I have the following issues/questions:

• as title it shows the first repo in the array of repositories (in the format nikku/wuffle)
• all columns are empty, even though I have an issue with the label “ready” (I’ve configured the columns as in the example config)
• when clicking on the top-right icon which should allow to log-in with GitHub I’m being eventually redirected to http://localhost:3000/board even though “localhost” never appears in the application configuration on GitHub
• When configuring the environment variables I wasn’t sue about the SESSION_SECRET, I then assumed I could enter an arbitrary String.
