 - ID must be unique
 
-# tasks::Duration
+### tasks::Duration
 - minutes should be less than 60
 
-# state::State (in state.toml)
+### state::State (in state.toml)
 - the `next_id` should always be greater than the ID of any task within the vault
 
-# index::Index (in state.toml)
+### index::Index (in state.toml)
 - the index of name to ID map should be correct given the names and IDs of all vaults
 
-# graph::Graph (in state.toml)
+### graph::Graph (in state.toml)
 - should always have dependencies the same as specified in each task file
 - no circular dependencies should be allowed to exist between tasks (and by extension should not exist in the state file)
