+## Variables
 
 To control the creation of UDF or SP macros with dbt run:
 * UPDATE_UDFS_AND_SPS
-When True, executes all macros included in the on-run-start hooks within dbt_project.yml on model run as normal
-When False, none of the on-run-start macros are executed on model run
+  * Default values are False
+  * When True, executes all macros included in the on-run-start hooks within dbt_project.yml on model run as normal
+  * When False, none of the on-run-start macros are executed on model run
 
-Default values are False
+  * Usage: `dbt run --vars '{"UPDATE_UDFS_AND_SPS":True}' -m ...`
 
-* Usage:
-dbt run --vars '{"UPDATE_UDFS_AND_SPS":True}'  -m ...
+Use a variable to heal a model incrementally:
+* HEAL_MODEL
+  * Default is FALSE (Boolean)
+  * When FALSE, logic will be negated
+  * When TRUE, heal logic will apply
+  * Include `heal` in model tags within the config block for inclusion in the `dbt_run_heal_models` workflow, e.g. `tags = 'heal'`
 
-To reload records in a curated complete table without a full-refresh, such as `silver_bridge.complete_bridge_activity`:
-* HEAL_CURATED_MODEL
-Default is an empty array []
-When item is included in var array [], incremental logic will be skipped for that CTE / code block  
-When item is not included in var array [] or does not match specified item in model, incremental logic will apply
-Example set up: `{% if is_incremental() and 'axelar' not in var('HEAL_CURATED_MODEL') %}`
+  * Usage: `dbt run --vars '{"HEAL_MODEL":True}' -m ...`
 
-* Usage:
-Single CTE: dbt run --vars '{"HEAL_CURATED_MODEL":"axelar"}' -m ...
-Multiple CTEs: dbt run --vars '{"HEAL_CURATED_MODEL":["axelar","across","celer_cbridge"]}' -m ...

+Use a variable to extend the incremental lookback period:
+* LOOKBACK
+  * Default is a string representing the specified time interval e.g. '12 hours', '7 days' etc.
+  * Example set up: `SELECT MAX(_inserted_timestamp) - INTERVAL '{{ var("LOOKBACK", "4 hours") }}'`
+
+  * Usage: `dbt run --vars '{"LOOKBACK":"36 hours"}' -m ...`
