 ## ToDo
 
-### Linea
+### Overrides

+Attempted to overcome false positives with:
+
+1. /styles/ignore which references the Consensys-common/ignore.txt text file (which should override Vale.Spelling)
+2. With styles/Consensys/Overridesyaml which is a dummy extend of "existence" to allow use of an exceptions
+list {I am not convinced this is working and its not a ssot method as it will need to repeat the ignore items 
+for Vale.Spelling}

-1. We seem to be using proper noun for Coordinator but not for prover
-2. Proper Linea Voyage
 
-### General
-2. Will links be false positives, e.g. Can linting for " CLI" work to avoid false positives for links?
-3. Can we use reject [here to prevent links being put in this format, is it covered another way?
