Customizing your self hosted instance
Go to http://your-instance.com/customizer/
You'll be able to set the desired logo and "single competition" to view on your instance.
To enable single competition mode set the SINGLE_COMPETITION_VIEW_PK environment variable. Set this to the Primary Key (ID) of the competition you'd like to use. You can grab the ID from the URL of the competition. For example, when you go to your competition the url may be http://localhost:8000/competitions/20 so in this case 20 is the PK of the competition.
In the case below, the PK is 1371
So you'd do something like
export SINGLE_COMPETITION_VIEW_PK=1371
