+### GitHub token
 
-## FAQ:
 Since GitHub allow to make only 50 requests without authentication it's recommended to run this script with token
 
 **You can easily [generate it here](https://github.com/settings/applications)**.
 
 And:
 
-- Run with key `-t [your-16-digit-token]` that 
+- Run with key `-t [your-16-digit-token]` 
 - Or set environment variable `CHANGELOG_GITHUB_TOKEN` and specify there your token. 
  		
-	i.e. add to your `~/.bash_profile` or `~/.zshrc` or any other place to load ENV variables string `export CHANGELOG_GITHUB_TOKEN="your-40-digit-github-token"'`
+	i.e. add to your `~/.bash_profile` or `~/.zshrc` or any other place to load ENV variables string :
+
+        export CHANGELOG_GITHUB_TOKEN="your-40-digit-github-token"
 
 So, if you got error like this:
 >! /Library/Ruby/Gems/2.0.0/gems/github_api-0.12.2/lib/github_api/response/raise_error.rb:14:in `on_complete'
 
 It's time to create this token or wait for 1 hour before GitHub reset the counter for your IP.
 
+##Features and advantages of this project
+- Generate canonical change log file, followed by [keepachangelog.com guidlines](http://keepachangelog.com/)
+- Simply add links for all closed issues and merged pull requests
+- Possible to generate **Unreleased** changes (closed issues that have not released yet)
+- Flexible format customisation:
+    - Customize issues, that should be added to changelog
+    - Custom date format supported 
+    - Ability to manually specify in which version issue was fixed (in case, when closed date is not match) by setting `milestone` of issue the same name as tag of  required version
+    - Ability to exclude specific issues from change log (by labels)
+        - Automatically exclude "questions" - issues marked as `question` labels (and other issues, that shouldn't be in change log file: with `duplicate invalid wontfix` labels)
+- Distinguish bug fixes, enchantments, and closed issues according labels.
+    - 	**Issues** (closed issues w/o any labels)
+    - **Merged pull-requests** (all merged pull-requests)
+    - **Bug-fixes** (by label `bug` in issue)
+    - **Enhancements** (by label `enhancement` in issue)
