-## Design
+## Reference material
 
-At a high level, littlefs is a block based filesystem that uses small logs to
-store metadata and larger copy-on-write (COW) structures to store file data.
+[DESIGN.md](DESIGN.md) - DESIGN.md contains a fully detailed dive into how
+littlefs actually works. I would encourage you to read it since the
+solutions and tradeoffs at work here are quite interesting.
 
-In littlefs, these ingredients form a sort of two-layered cake, with the small
-logs (called metadata pairs) providing fast updates to metadata anywhere on
-storage, while the COW structures store file data compactly and without any
-wear amplification cost.
-
-Both of these data structures are built out of blocks, which are fed by a
-common block allocator. By limiting the number of erases allowed on a block
-per allocation, the allocator provides dynamic wear leveling over the entire
-filesystem.
