 ## Steps
 
-- Get a running simulator id with `xcrun simctl list devices`
-- Create template Flashlight in Xcode Instruments (with cpu-profile and memory usage)
-- Add your own test in `test.yaml`
-- `PLATFORM=ios-instruments node packages/commands/test/dist/bin.js test --bundleId <YOUR_APP_ID> --simulatorId 9F852910-03AD-495A-8E16-7356B764284 --testCommand "maestro test test.yaml" --resultsFilePath "./result.json"`
+PLATFORM=ios-instruments node packages/commands/test/dist/bin.js test --bundleId <YOUR_APP_ID> --testCommand "maestro test test.yaml" --resultsFilePath "./result.json"`
 
 - Check the results in the web-reporter
   `yarn workspace @perf-profiler/web-reporter build`
