 Atmosphère is a work-in-progress customized firmware for the Nintendo Switch.
 
+
+### Stratosphère (Custom Sysmodule(s)) - In Progress
+
+For user's benefits, we'll likely want custom sysmodules -- both of the Rosalina style to extend the kernel/provide new features, and of the loader re-implementation style to hook important system actions.
+
+
+### Troposphère (Application-level Horizon OS patches) - In Progress
+
+Patches will need to be developed for Horizon to implement desirable CFW features.
+
+
+
+### Thermosphère (EL2 Emunand support) - In Progress
+
+In the absence of a released coldboot entrypoint, Atmosphère will want to support backing up and using virtualized/redirected NAND images.
+
+
+### Exosphère (Customized TrustZone) - In Progress
+
+Atmosphère will want to run a customized Secure Monitor.
+
+
+### Fusée (First-stage Loader) - In Progress
+
+Atmosphère will need a loader -- this will be responsible for loading and validating stage 2 (custom TrustZone) plus package2 (Kernel/FIRM sysmodules), and patching them as needed. (This should implement all functionality normally in Package1loader/NX Bootloader).
