The knative/eventing issue 2376 (opened, I supposed, by the OP) includes an explanation from Vincent (houshengbo):

Vincent refers to Knative Eventing / Sources, about how to install the eventing sources.

GitHubSource is one of them, and all the available sources are be found here.
The repo is https://github.com/knative/eventing-contrib.

However, there should be instruction on how to install the sources: Install Knative Eventing.
Those instructions also install the default eventing sources, including the GitHubSource we'll use.

I have not found any.

I guess you need to install it by

kubectl apply -f https://github.com/knative/eventing-contrib/releases/download/v0.11.0/github.yaml

for 0.11.0.
