 To test your new language translation, you have two options:
 
-##### Option 1: Using `npm` symlinks
+##### Option 1: Using a symlink
 
-Create a symlink to test your local changes without publishing:
+From the workspace root, run the `symlink` script. It builds all packages, resolves `catalog:` and `workspace:*` references, and prints ready-to-paste override snippets:
 
 ```bash
-# Navigate to the i18n package
-cd packages/i18n
+pnpm symlink
+```
 
-# Create a global symlink
-npm link
+Copy the relevant snippet from the output into your test project's `package.json` and run `pnpm install` (or the equivalent for your package manager):
 
-# Navigate to your test application
-cd /path/to/your/test-app
+###### pnpm
 
-# Link the local i18n package
-npm link @asgardeo/i18n
+```json
+{
+  "pnpm": {
+    "overrides": {
+      "@asgardeo/i18n": "file:/path/to/javascript/packages/i18n"
+    }
+  }
+}
 ```
 
-For more information about npm symlinks, see the [npm link documentation](https://docs.npmjs.com/cli/v10/commands/npm-link).

+/**
+ * Prepares local packages for symlinking into external projects.
+ *
+ * Problems this solves:
+ *  - `catalog:` references in package.json are a pnpm workspace-only protocol.
+ *    External consumers (even via `file:`) can't resolve them.
+ *  - `workspace:*` references must become `file:` paths so the external project
+ *    resolves inter-package dependencies to the local builds too.
+ *
+ * What it does:
+ *  1. Reads the `catalog:` entries from pnpm-workspace.yaml.
+ *  2. Builds all packages (pnpm build:packages).
+ *  3. Patches every `packages/<*>/package.json`, replacing:
+ *       `"catalog:"` → the real version string from the catalog
+ *       `"workspace:*"` → `"file:<absolute-path-to-package>"`
+ *  4. Prints ready-to-paste override snippets for pnpm and npm.
+ *
+ * To restore the source files after you're done:
+ *   git checkout packages/<*>/package.json
