+## Jujutsu's Core Tenets
+
+Jujutsu's core tenets are:
+
+ * Separation of logic and UI: It should be as easy to create new UIs (CLIs,
+   GUIs, TUIs, servers) without having to duplicate logic.
+ * Easy-to-use APIs: It should be easy to create new commands. For example,
+   each command should not have to worry about concurrency, working-copy state,
+   and rebasing descendants of rewritten commits.
+ * User-friendliness: Making the working copy a commit is simpler. This is
+   how the project started.
+ * The repository is the source of truth: Most commands should operate on the
+   commit graph. The working copy is just one way of editing commits.
+ * Pluggable storage: Must be easy to integrate with different commit storage,
+   virtual file systems and more.
+ * Git-interop: Git is everywhere. We need to have good interop to be adopted.
+ * All operations must be able to scale to Google-scale repos (lots of commits,
+   lots of files): Laziness is important, must avoid accessing data
+   unnecessarily.
+ * Having as few states as possible.
+ * Make it incredibily hard to lose work in your repository.
+ * Concurrent modifications to the repo should be safe.
+ * Allow concurrent edits on any commit, pending or finished.
+ * Make a "stacked diffs" workflow as easy as possible.
