 - simplified configuration of hostnames and `ActionMailer` with a YAML file
 
+### http_accept_language
+
+To install `http_accept_language` you just have to add a line in your `ApplicationController`
+
+```ruby
+class ApplicationController < ActionController::Base
+  include HttpAcceptLanguage::AutoLocale
+
+end
+```
+
+### Dotenv
+
+It's a good practice to not include credentials for third party services in your code. You can defined it in a `.env` file which I recommend to not include in your git repository.
+
 ### Exception Notification
 
 If `exception` is not set in `jt-toolbox.yml` file, Exception Notification is disabled.
 In addition to the default ignored exceptions, the following exceptions are also muted:
 
 - `ActionController::InvalidCrossOriginRequest`
 - `ActionController::InvalidAuthenticityToken`
+
+### Airbrake
+
+If `airbrake` is not set in `jt-toolbox.yml` file, Airbrake is disabled.
 
 ### Paperclip
 
 - `convert_options` is set to `-strip`, which means all metadata of images are removed, this is used for reduced the weight of images.
 - `use_timestamp` is et to `false`, it's a good practice to have unique url for image and url without parameters, instead of using the timestamp we use the fingerprint of the image. [More informations here.](https://github.com/thoughtbot/paperclip#md5-checksum--fingerprint)
