 ```ruby
 SomeActiveRecordClass.where_lower(attribute1: 'AbC', attribute2: ['stRing', 123, :symBol], attribute3: ('AA'..'AZ'))
 ```
 
+Since `0.3.0`  
+You can pass a nested hash (1 level deep only) for association condition
+```ruby
+record.association_records.where_lower(association_table: {association_column: value})
+```
+
+You can also add table name in key if you are using it with association  
+I don't plan to support any "smart" table guessing though
+```ruby
+record.association_records.where_lower('association_table.association_column' => value)
+```
