 ### Validating the session
 
-If the `validate` function return `false`, throws an exception, returns a
-Promise that resolves to `false` or rejects, or contains any failing Cypress
-command, the session will be considered invalid, and `setup` will be re-run.
+The `validate` function is used to ensure the session has been correctly
+established. This is especially helpful when a cached session is being restored,
+because if the session is not valid, `cy.session()` will recreate the session by
+re-running `setup`.
+
+The following scenarios will mark the session as invalid:
+
+- the `validate` function throws an exception
+- the `validate` function returns a Promise that resolves to `false` or rejects
+- the `validate` function contains failing Cypress command
+- the last Cypress command in the `validate` function yielded `false`
