+== Installing with a persistent NixOS installer
+
+In some cases such as my main desktop configuration, it may be impossible to install it with a typical installer image like the official ISO.
+This is because the typical installer environment boots on a 2GB tmpfs which should be enough for most environments.
+Buuuuuut several of my NixOS configurations are not that, they basically contain at least 24GB of shenanigans and the collective build files resulting from it is simply not enough in a little 2GB tmpfs and most likely creates a system crash.
+For this reason, it is very recommended to create an installer environment with a persistent live installer.
+
+To do so, simply partition your storage device (e.g., a flash drive, external hard drive) of at least >=64GB.
+Then, you'll have to install a NixOS system in the partition with `graphical-installer` NixOS configuration found in the project flake.
+As widespread throughout the project, you can use disko to install the system in a one-liner.
