 # Driver
 
 Driver is a wrapper class that persists and retrieves values from backend. It needs to implement:
-- `inc(key:, **values)` method to store values
+
+- `inc(key:, **values)` method add values
+- `set(key:, **values)` method set values
 - `get(key:)` method to retrieve values
 
-## Packer Mixin
+## Documentation
 
-Some databases cannot store nested hashes/values. Or they cannot perform increment on nested values that does not exist. For this reason you can use Packer mixin that helps you convert values to dot notation.
-
-```ruby
-class Sample
-  include Trifle::Stats::Mixins::Packer
-end
-
-values = { a: 1, b: { c: 22, d: 33 } }
-=> {:a=>1, :b=>{:c=>22, :d=>33}}
-
-packed = Sample.pack(hash: values)
-=> {"a"=>1, "b.c"=>22, "b.d"=>33}
-
-Sample.unpack(hash: packed)
-=> {"a"=>1, "b"=>{"c"=>22, "d"=>33}}
-```

-## Dummy driver
-
-Sample of using custom driver that does, well, nothing useful.
-
-```ruby
-irb(main):001:1* class Dummy
-irb(main):002:2*   def inc(key:, **values)
-irb(main):003:2*     puts "Dumping #{key} => #{values}"
-irb(main):004:1*   end
-irb(main):005:2*   def get(key:)
-irb(main):006:2*     puts "Random for #{key}"
-irb(main):007:2*     { count: rand(1000) }
-irb(main):008:1*   end
-irb(main):009:0> end
-=> :get
-
-irb(main):010:0> c = Trifle::Stats::Configuration.new
-=> #<Trifle::Stats::Configuration:0x00007fe179aed848 @separator="::", @ranges=[:minute, :hour, :day, :week, :month, :quarter, :year], @beginning_of_week=:monday, @time_zone="GMT">

-irb(main):011:0> c.driver = Dummy.new

-
-irb(main):012:0> c.track_ranges = [:minute, :hour]
-=> [:minute, :hour]
-
-irb(main):013:0> Trifle::Stats.track(key: 'sample', at: Time.now, values: {count: 1}, config: c)
-Dumping sample::minute::1611696240 => {:count=>1}
-Dumping sample::hour::1611694800 => {:count=>1}
-=> [{2021-01-26 21:24:00 +0000=>{:count=>1}}, {2021-01-26 21:00:00 +0000=>{:count=>1}}]
-
-irb(main):014:0> Trifle::Stats.values(key: 'sample', from: Time.now, to: Time.now, range: :hour, config: c)
-Random for sample::hour::1611694800
-=> [{2021-01-26 21:00:00 +0000=>{:count=>405}}]
