Where is documentation for `/boot/config-<kernel_version>`?

I am working on understanding of how cgroups memory resource controller is enabled on Ubuntu 20.04. I have several Ubuntu machines that make up a Slurm 23.02.7 cluster. In cgroup.conf , SchedMD states : > Debian and derivatives (e.g. Ubuntu) usually exclude the memory and memsw (swap) cgroups by default. To include them, add the following parameters to the kernel command line: cgroup_enable=memory swapaccount=1 If I follow this advise and do :

root@node01:~# grep CONFIG_MEMCG /boot/config-5.4.0-169-generic
CONFIG_MEMCG=y
CONFIG_MEMCG_SWAP=y
# CONFIG_MEMCG_SWAP_ENABLED is not set
CONFIG_MEMCG_KMEM=y

It seems that contrary to SchedMD's opinion, the cgroups memory controller is already enabled by default. However, I'd like formal documentation about what exactly every variable is in /boot/config-5.4.0-169-generic. I've searched for an associated man page, but cannot find one. **Question** : 1. What man page or other documentation exists describing the configurations set in /boot/config-5.4.0-169-generic?
