 ## 📝 Usage
 
-First, you'll need to generate a migration to add the prefix_id column to your model(s).
+Add `has_prefix_id :my_prefix` to your models to autogenerate prefixed IDs.
 
 ```ruby
-class AddPrefixIdToUsers< ActiveRecord::Migration
-  def change
-    add_index :users, :prefix_id, unique: true
-  end
+class User < ApplicationRecord
+  has_prefix_id :user
 end
 ```
 
-It's important the `prefix_id` column is indexed and unique.
+This will generate a value like `user_1234abcd`.
 
-Then you can add `has_prefix_id :my_prefix` to your models to autogenerate prefixed IDs.
+To query using the prefixed ID, simply you can use either `find` or `find_by_prefixed_id`:
 
 ```ruby
+User.find("user_5vJjbzXq9KrLEMm32iAnOP0xGDYk6dpe")
+User.find_by_prefix_id("user_5vJjbzXq9KrLEMm32iAnOP0xGDYk6dpe")
+```
+
+We also override `to_param` by default so it'll be used in URLs automatically.
+
+To disable find and to_param overrides, simply pass in the options:
+
+```ruby
 class User < ApplicationRecord
-  has_prefix_id :user
+  has_prefix_id :user, override_find: false, override_param: false
 end
 ```
 
-This will generate a value like `user_1234abcd` in the User's `prefix_id` column.
+### Generic lookup
 
+Imagine you have a prefixed ID but you don't know which model it belongs to.
+
+```ruby
+PrefixedIds.find("user_5vJjbzXq9KrLEMm3")
+#=> #<User>
+PrefixedIds.find("acct_2iAnOP0xGDYk6dpe")
+#=> #<Account>
+```
+
 ### Customizing
 
 You can customize the prefix, length, and attribute name for PrefixedIds.
 
 ```ruby
 class Account < ApplicationRecord
-  has_prefix_id :acct, attribute: :my_id, length: 32
+  has_prefix_id :acct, minimum_length: 32, override_find: false, to_param: false
 end
 ```
