The best place to start exploring the conkw you just installed is by typing http://localhost:12789/. Replace localhost by the name of the computer you installed conkw on if it is another computer.
There you will find a few things:
This is the list of the grabbers available to you in conkw. Each of them has a default UI that will show you what you can do with them. You can basically classify the grabbers in three categories:
Maybe you're already there, but maybe you're reading this from github, or directly from the files you checked out. The documentation is also available as a website on your newly installed conkw instance !
A link to the github of conkw. Issues, community and source code, a precious resource !
This is where you will customize your UI to your needs and tastes !
There is already something in there, that was build at installation time. You can keep it on the side or override it. Any conkw update will leave this space untouched, save from recreating index.html if it doesn't exist.
On the left of the page, there is a clock. Click on it and you will change the clock face. There are a few available, we hope you'll get to like at least one. Otherwise, you can write your own
