If you decide to open an issue in this repository, please fill in all information the [issue template](https://github.com/cypress-io/code-coverage/blob/master/.github/ISSUE_TEMPLATE/bug_report.md) asks for. The issues most likely to be resolved have debug logs, screenshots, and hopefully public repository links so we can try running the tests ourselves.
+### Coverage reporting timeouts
+
+If the plugin times out when sending coverage report data to be merged, this may be due to a very large
+report being sent across processes. You can batch the report by setting the `sendCoverageBatchSize` environment
+variable in your `cypress.config.js` file's 'env' section. Assign the variable an integer value representing
+the number of report keys to send per batch.
+
## Contributing
You can test changes locally by running tests and confirming that the code coverage has been calculated and saved.
