By default, the ansible-doc command will use module as the type, thus the -t or --type option followed by strategy must be used to display documentation on strategy.
The -l or --list option can be used to list the strategy documentation.
ansible-doc --type strategy --list
debug Executes tasks in interactive debug session
free Executes tasks without waiting for all hosts
host_pinned Executes tasks on each host without interruption
linear Executes tasks in a linear fashion
Let's say you want to learn about "linear". The -s or --snippet option can be used.
ansible-doc --type strategy --snippet linear
