+For each of the 💚 implemented and thoroughly tested 💚 databases, we'll provide examples of `data-diff` input code and outputs on various data structures and sizes.

 #### Smaller Data Set with Conflicting Values
 
 In this example, we use the CLI to compare a smaller data set with one missing row (`where actor_id = 4`) as well as several conflicting values:
-- `Ed` misspelled as `Edd` `where actor_id = 3` (or is `Edd` misspelled as `Ed`? Hard to say!)
-- Conflicting `last_update` values `where actor_id = 3` and `where actor_id = 2'
-- Conflicting spellings of the `first_name` `Penelope`/`Penelop` `where actor_id = 1`
+- `Ed` is misspelled as `Edd`. (Or is `Edd` misspelled as `Ed`? Hard to say!)
+- `Ed`/`Edd` and `Nick` have conflicting `last_update` values.
+- There's one more conlicting `first_name` spelling: `Penelope` vs `Penelop`.
