+## Existing Replicator Strategies
+
+Before writing a new kind of Replicator Strategy, check below to see if your
+resource can already be handled by one of the existing strategies. Consult with
+the Geo team if you are unsure.
+
+### Blob Replicator Strategy
+
+Models that use
+[CarrierWave's](https://github.com/carrierwaveuploader/carrierwave) `Uploader::Base`
+can be easily supported by Geo with the `Geo::BlobReplicatorStrategy` module.
+
+First, each file should have its own primary ID and model. Geo strongly
+recommends treating *every single file* as a first-class citizen, because in
+our experience this greatly simplifies tracking replication and verification
+state.
+
+For example, to add support for files referenced by a `Widget` model with a
+`widgets` table, you would perform the following steps:
+
+1. Add verification state fields to the `widgets` table so the Geo primary can
+   track verification state:
+
+   ```ruby
+   # frozen_string_literal: true
+
+   class AddVerificationStateToWidgets < ActiveRecord::Migration[6.0]
+     DOWNTIME = false
+
+     def change
+       add_column :widgets, :verification_retry_at,  :datetime_with_timezone
+       add_column :widgets, :last_verification_ran_at,  :datetime_with_timezone
+       add_column :widgets, :verification_checksum, :string
+       add_column :widgets, :verification_failure, :string
+       add_column :widgets, :verification_retry_count, :integer
+     end
+   end
+   ```
+
+1. Add a partial index on `verification_failure` to ensure re-verification can
+   be performed efficiently:
+
+   ```ruby
+   # frozen_string_literal: true
+
+   class AddVerificationFailureIndexToWidgets < ActiveRecord::Migration[6.0]
+     include Gitlab::Database::MigrationHelpers
+
+     DOWNTIME = false
+
+     disable_ddl_transaction!
+
+     def up
+       add_concurrent_index :widgets, :verification_failure, where: "(verification_failure IS NOT NULL)", name: "widgets_verification_failure_partial"
+     end
+
+     def down
+       remove_concurrent_index :widgets, :verification_failure
+     end
+   end
+   ```
+
+1. Include `Gitlab::Geo::ReplicableModel` in the `Widget` class, and specify
+   the Replicator class `with_replicator Geo::WidgetReplicator`.
+
+   At this point the `Widget` class should look like this:
+
+   ```ruby
+   # frozen_string_literal: true
+
+   class Widget < ApplicationRecord
+     include ::Gitlab::Geo::ReplicableModel
+
+     with_replicator Geo::WidgetReplicator
+
+     mount_uploader :file, WidgetUploader
+
+     ...
+   end
+   ```
+
+1. Create `ee/app/replicators/geo/widget_replicator.rb`. Implement the
+   `#carrierwave_uploader` method which should return a `CarrierWave::Uploader`.
+   And implement the private `#model` method to return the `Widget` class.
+
+   ```ruby
+   # frozen_string_literal: true
+
+   module Geo
+     class WidgetReplicator < Gitlab::Geo::Replicator
+       include ::Geo::BlobReplicatorStrategy
+
+       def carrierwave_uploader
+         model_record.file
+       end
+
+       private
+
+       def model
+         ::Widget
+       end
+     end
+   end
+   ```
+
+1. Create `ee/spec/replicators/geo/widget_replicator_spec.rb` and perform
+   the setup necessary to define the `model_record` variable for the shared
+   examples.
+
+   ```ruby
+   # frozen_string_literal: true
+
+   require 'spec_helper'
+
+   describe Geo::WidgetReplicator do
+     let(:model_record) { build(:widget) }
+
+     it_behaves_like 'a blob replicator'
+   end
+   ```
+
+1. Create the `widget_registry` table so Geo secondaries can track the sync and
+   verification state of each Widget's file:
+
+   ```ruby
+   # frozen_string_literal: true
+
+   class CreateWidgetRegistry < ActiveRecord::Migration[5.2]
+     DOWNTIME = false
+
+     def change
+       create_table :widget_registry, id: :serial, force: :cascade do |t|
+         t.integer :widget_id, null: false
+         t.integer :state, default: 0, null: false
+         t.integer :retry_count, default: 0
+         t.string :last_sync_failure, limit: 255
+         t.datetime_with_timezone :retry_at
+         t.datetime_with_timezone :last_synced_at
+         t.datetime_with_timezone :created_at, null: false
+
+         t.index :widget_id, name:  :index_widget_registry_on_repository_id, using: :btree
+         t.index :retry_at, name: :index_widget_registry_on_retry_at,  using: :btree
+         t.index :state, name: :index_widget_registry_on_state, using:  :btree
+       end
+     end
+   end
+   ```
+
+1. Create `ee/app/models/geo/widget_registry.rb`:
+
+   ```ruby
+   # frozen_string_literal: true
+
+   class Geo::WidgetRegistry < Geo::BaseRegistry
+     include Geo::StateMachineRegistry
+
+     belongs_to :widget, class_name: 'Widget'
+   end
+   ```
+
+1. Create `ee/spec/factories/geo/widget_registry.rb`:
+
+   ```ruby
+   # frozen_string_literal: true
+
+   FactoryBot.define do
+     factory :widget_registry, class: 'Geo::WidgetRegistry' do
+       widget
+       state { Geo::WidgetRegistry.state_value(:pending) }
+
+       trait :synced do
+         state { Geo::WidgetRegistry.state_value(:synced) }
+         last_synced_at { 5.days.ago }
+       end
+
+       trait :failed do
+         state { Geo::WidgetRegistry.state_value(:failed) }
+         last_synced_at { 1.day.ago }
+         retry_count { 2 }
+         last_sync_failure { 'Random error' }
+       end
+
+       trait :started do
+         state { Geo::WidgetRegistry.state_value(:started) }
+         last_synced_at { 1.day.ago }
+         retry_count { 0 }
+       end
+     end
+   end
+   ```
+
+1. Create `ee/spec/models/geo/widget_registry.rb`:
+
+   ```ruby
+   # frozen_string_literal: true
+
+   require 'spec_helper'
+
+   describe Geo::WidgetRegistry, :geo, type: :model do
+     let_it_be(:registry) { create(:widget_registry) }
+
+     specify 'factory is valid' do
+       expect(registry).to be_valid
+     end
+   end
+   ```
+
+Widget files should now be replicated and verified by Geo!
