Yes, but it is outdated. It has grown quite different from the architect installer. The most up to date primer is probably this tutorial:
It now uses the task based menu structure that @sueridgepipe envisioned: after mounting partitions you choose what you want to do: install desktop system, just the base system, some kind of custom system (unconfigured desktops) or do system rescue tasks.
You get to choose from all kernels provided by mhwd. Desktop system is the basic case: it let’s you choose from all existing manjaro editions, by using manjaro iso-profiles as a template. All options also let you add arbitary extra packages, choose exact drivers with mhwd, chroot to installation and choose the default shell for created users. Oh, and you can choose bootloader as well (grub, systemd-boot, refind).
Also worth mentioning is btrfs support. Almost all the usual kinks have been ironed out: sane mount options are suggested based on whether the disk is ssd or not, grub is automatically configured not to throw errors, right hooks are added to mkinitcpio.conf, TLP is configured to avoid filesystem corruption, grub-btrfs is set and so on. The default subvolume layout is sane and you can freely set your own layout if you want to.
But this is getting way off topic. Sorry about that…
