 Verifies that the container_structure_test bazel rule exposed by this project works properly.
 
+## Running tests with pre-compiled toolchain
+
 ```sh
 cd bazel/test
 bazel test ...
 bazel test --enable_bzlmod ...
-```
+```
+
+## Testing with local changes (non-pre-compiled toolchain)
+
+When developing changes, you may want to test your modifications before they're compiled a release. Here's how to test with a locally built binary:
+
+1. Build your local binary:
+   ```sh
+   go build -o /tmp/container-structure-test-local ./cmd/container-structure-test/
+   ```
+
+2. Temporarily modify `bazel/container_structure_test.bzl`:
+   ```sh
+   sed -i.bak 's|readonly st=$(rlocation {st_path})|readonly st="/tmp/container-structure-test-local"|g' bazel/container_structure_test.bzl
+   ```
+
+3. Run the bazel test:
+   ```sh
+   cd bazel/test
+   bazel test :test --test_output=all
+   ```
+
+4. Restore the original rule:
+   ```sh
+   mv bazel/container_structure_test.bzl.bak bazel/container_structure_test.bzl
+   ```
+
+This allows you to verify that your changes work correctly with the bazel integration before submitting them.
