+One can also specify the directory or directories to use via the `directories` input (which defaults to `src`). E.g.
+```yaml
+
+      - uses: julia-actions/julia-processcoverage@v1
+        with:
+          directories: src,examples
+      - uses: codecov/codecov-action@v1
+        with:
+          file: lcov.info
+```
+instructs the action to look for coverage information in both `src` and an `examples` folder. Likewise, use
+```yaml
+      - uses: julia-actions/julia-processcoverage@v1
+        with:
+          directories: path/to/subdir/package/src
+      - uses: codecov/codecov-action@v1
+        with:
+          file: lcov.info
+```
+to get coverage information from a package in a subdirectory of the repo.
