and migration overview pages so developers migrating from v0.5.3 can
discover and use the automated migration tooling.

 A direct migration from v0.5.3 to v1.0.0 touches **20+ files** per app with deep, scattered rewrites. The compat layer reduces this to **~5 file changes** per app.

+Before migrating manually, try the [yellow-sdk-codemod](https://github.com/layer-3/yellow-sdk-codemod). It rewrites imports, renames auth fields, migrates client constructors, updates `package.json`, and flags RPC patterns with `// TODO [codemod]` comments for the remaining manual steps.

+## Automated Migration with Codemod
+
+If you are migrating an existing codebase from `@erc7824/nitrolite` (v0.4–v0.5.3) or `@layer-3/nitrolite`, the [yellow-sdk-codemod](https://github.com/layer-3/yellow-sdk-codemod) tool can automate much of the upgrade for you.
+
+:::tip Codemod available
+Run the codemod to handle import rewrites, client constructor migration, auth field renames, and package.json updates automatically. Patterns that require manual judgment (RPC call collapse, WebSocket removal) are flagged with `// TODO [codemod]` comments pointing to the exact replacement.
+
+```bash
+# Scan your codebase for old patterns (no changes made)
+npx tsx src/cli.ts scan --path ./src
+
+# Apply all transforms + update dependencies
+npx tsx src/cli.ts run --path ./src --update-deps
+```
+
+See the [codemod README](https://github.com/layer-3/yellow-sdk-codemod#readme) for the full list of transforms and options.
