 #### Here is an overview of the main features currently included in the app:
 - This project is written for Android! No need for some kind of janky laptop charging setup.
-- Similar to ScoutingPASS, there are many diffrent types of fields that can be used to collect data.
-- The app is designed to handle updates to the fields on the fly, without loosing any data!
+- Similar to ScoutingPASS, many different types of fields can be used to collect data.
+- The app is designed to handle updates to the fields on the fly, without losing any data!
 - Unlike other scouting solutions, scouters can disable any field they did not measure, and disabled fields will not be included in any calculations.
-- Dynamic displays based off of the diffrent fields.
+- Dynamic displays based on the different fields.
 - Data transfer including 2D codes, Bluetooth, and File Bundle.
 - Exporting using CSV.
 - Deployment on F-Droid

 #### Things that are yet to be implemented:
 - A page that lets users cross-compare scouting data between teams. (Compare)
-- A page that lets scouters more easily make reports to the drive team before a match starts (Report)
 
 #### Things that may or may not be implemented:
-- Statbotics intgration
+- Statbotics integration
 - Scout error estimation using OPR-like calculation
 - - Would most likely require Statbotics
