 ### Guidelines 
 
-1. You must run the `spotlessApply` task before commiting, either through Android Studio or with `./gradlew spotlessApply`.
+1. You must run the `spotlessApply` task before committing, either through Android Studio or with `./gradlew spotlessApply`.
 2. A PR should be focused and contained. If you are changing multiple unrelated things, they should be in separate PRs.
 3. A PR should fix a bug or solve a problem - something that only you would use is not necessarily something that should be published.
 4. Give your PR a detailed title and description - look over your code one last time before actually creating the PR. Give it a self-review.
