+# workspace example
+
+Minimal Bun workspace-style layout with two packages:
+
+- `@workspace/pkg-a`: exports a string helper
+- `@workspace/pkg-b`: imports from `pkg-a` and prints the message
+
+The workspace root also defines a Bun `catalog` pin for `lodash`, and both packages consume it via `"lodash": "catalog:"` to keep versions consistent across packages.
+
+This example demonstrates building a target from a workspace-shaped directory tree with Bazel:
+
+```bash
+bazel build //examples/workspace:pkg_b_bundle
+```
