+### Adding benchmarking for new react-native versions
+
+ Currently this repository only holds information around benchmarking of N rendered views, texts & images. If you have benchmarked the new react-native version against mentioned scenarios either by upgrading react-native versions in existing project, by using existing tool or in freshly crafted react-native project please make sure to add the benchmarking numbers under **Reports** directory in same format as other versions. In order to make sure the versions is comparable with other versions you will also need to add the versions for which benchmarking is done under **Webpage/supportedVersions.json**. By default if benchmarking is done using existing automation script the data will be dumped automatically in respective formats.
+
+ Also, for making the comparsion more promising we encourgage to get benchmarking numbers on same environment as we have for other versions.
+ Older version are benchmarked on the following devices for 30 itertions:
+ - Android Emulator: Pixel 3A API 34
+ - iOS Simulator: iPhone 15 Pro (17.2)
+
+ If you want to add or would like to have benchmarking of other scenarios like time taken to make a bridge, JSI calls for respective react-native versions feel to submit a new pull request with this data or open a feature request for the same.
+ We will more than happy to incorporate the changes so that it's available to consume on wider forums.
+
+ While adding benchmarking of new scenrios currently not available in this project it will be great addon to also add a simple webpage for quicker comparsion like we have for comparing time taken to render N views, texts & images inside **Webpage** directory of the project.
