+Packages for performant sequences of `Data.Map` differences.
+
+We follow processes and guidelines as established by the Consensus team at IOG.
+A nice starting point for reading `ouroboros-consensus` documentation is
+[ouroboros-network/ouroboros-consensus/README.md](
+https://github.com/input-output-hk/ouroboros-network/blob/master/ouroboros-consensus/README.md).
+
+
+## Usage
+
+Below is a simple example of defining a sequence of differences using
+root-measured finger trees and diffs. For more in-depth information about
+root-measured finger trees and diffs, read the following two READMEs. It is
+recommended to read them in order, because the documentation of `fingertree-rm`
+will justify choices and goals for `diff-containers`.
+
+* See [fingertree-rm/README.md](./fingertree-rm/README.md)
+* See [diff-containers/README.md](./diff-containers/README.md)
+
+```haskell
+import qualified Data.Map.Diff.Strict as Diff
+import qualified Data.FingerTree.RootMeasured.Strict as FTRM
+
+-- | A sequence of differences as a root-measured finger tree, storing the total
+-- sum of diffs at the root, and the length of sub-sequences in each node of the
+-- finger tree tree.
+type DiffSeq k v = FTRM.StrictFingerTree (Diff k v) (Sum Int) (Diff k v)
+
+instance RootMeasured (Diff k v) (Diff k v) where
+  measureRoot = id
+
+instance Measured (Diff k v) (Sum Int) where
+  measure = const 1
