Issue #1:

In section "Prepare OpenShift for Project Quay Builds", step 1, the command to create new OCP project is wrong, the correct command is "oc new-project builder"

oc create project builder
Error: must specify one of -f and -k

See 'oc create -h' for help and examples

Issue #2:

In section "Enable Builders and add Build Configuration to Project Quay’s Configuration Bundle", for parameter QUAY_USERNAME and QUAY_PASSWORD, Quay documents need to clarify, this credentials is used to pull image for WORKER_IMAGE
