+#### reportFilename replacement tokens
+
+Using the following tokens it is possible to dynamically alter the filename of the generated report.
+
+- **[name]** will be replaced with the spec filename when possible.
+- **[status]** will be replaced with the status (pass/fail) of the test run.
+- **[datetime]** will be replaced with a timestamp. The format can be - specified using the `timestamp` option.
+
+For example, given the spec `cypress/integration/sample.spec.js` and the following config:
+
+```
+{
+  reporter: "mochawesome",
+  reporterOptions: {
+    reportFilename: "[status]_[datetime]-[name]-report",
+    timestamp: "longDate"
+  }
+}
+```
+
+The resulting report file will be named `pass_February_23_2022-sample-report.html`
+
+**Note:** The `[name]` replacement only occurs when mocha is running one spec file per process and outputting a separate report for each spec. The most common use-case is with Cypress.
