 ## Influxer
 
-Use InfluxDB in your Rails (>4.0) application.
+ActiveRecord-like wrapper for [influxdb-ruby](https://github.com/influxdb/influxdb-ruby) with many useful features, such as:
+- Familar query language (use `select`, `where`, `not`, `group` etc).
+- Support for Regex conditions: `where(page_id: /^home\/.*/) #=> select * ... where page_id=~/^home\/.*/`.
+- Special query methods for InfluxDB: 
+    - `time` - group by time (e.g. `Metrics.time(:hour) => # select * ... group by time(1h)`);
+    - `past` - get only points for last hour/minute/whatever (e.g. `Metrics.past(:day) => # select * ... where time > now() - 1d`);
+    - `since` - get only points since date (e.g. `Metrics.since(Time.utc(2014,12,31)) => # select * ... where time > 1419984000s`);
+    - `merge` - merge series.
+- Scopes support
+    ```
+    class Metrics < Influxer::Metrics
+        default_scope -> { time(:hour).limit(1000) }
+        scope :unlimited, -> { limit(nil) }
+        scope :by_account, -> (id) { where(account_id: id) if id.present? }
+    end
 
-### Basic support
+    Metrics.by_account(1)
+    # => select * from "metrics" group by time(1h) where account_id=1 limit 1000
 
-ToDo
+    Metrics.unlimited.by_account(1).time(:week)
+    # => select * from "metrics" group by time(1w) where account_id=1
 
-### ActiveRecord 
+    ```
+- Support for handling fanout series as one metrics.
+    ```
+    class Metrics < Influxer::Metrics
+        fanout :account, :user, :page
+    end
 
-`has_metrics`
+    Metrics.where(account: 1)
+    # => select * from "metrics_account_1" 
 
-ToDo
+
+    Metrics.where(page: 'home').where(user: 12)
+    # => select * from "metrics_user_12_page_home" 
+
+    Metrics.where(page: /(home|faq)/).where(account: 1).where(user: 12)
+    # => select * from /^metrics_account_1_user_12_page_(home|faq)$/ 
+
+    ``` 
+- Integrate with your model:
+    ```
+    class UserVisits < Influxer::Metrics
+    end
+    
+    class User < ActiveRecord::Base
+        has_metrics :visits
+    end
+
+    user = User.find(1)
+    user.visits.write(page_id: 'home')
+    #=> < creates point {user_id: 1, page_id: 'home'} in 'user_visits' series >
+
+    user.visits.where(page_id: 'home')
+    #=> select * from user_visits where page_id='home'
+    ```
