 3. Keys for common accessibility strings must start by `a11y_`. Example: `a11y_hide_password`
 4. Otherwise, try to group keys logically and nest where appropriate, such as `keyboard_` for strings relating to keyboard shortcuts.
 5. Ensure your translation keys do not include `.` or `|` or ` `. Try to balance string length against descriptiveness.

 There you can also require all translations to be redone if the meaning of the string has changed significantly.
 
+### Editing English UK (en_EN) strings

+Edits to `en_EN.json` **require** a PR, since there is a high chance that a test covers the string in use and may be impacted if it were to change. This also gives us a clean change history.

+When changing a string, be careful to rename the key if the meaning changes. For instance, if the key `button_click_biscuits` changed from "Click for biscuits" to "Click for vegetables", then they key should have changed to `button_click_vegetables`.

 ## Removing existing strings
 
 You can remove an existing string by removing the key from `en_EN.json`. Do not modify other language json files for this purpose.
