-## Real examples:
+### GitHub token
-### [This changelog](https://github.com/skywinder/ActionSheetPicker-3.0/blob/master/CHANGELOG.md) was generated by

-## FAQ
+Since GitHub allow to make only 50 requests without authentication it's recommended to run this script with token
-Since GitHub allow to make only 50 requests without authentication it's recommended to run this scrip with key `-t [your 16 digit token]` that you can easily **[generate here](https://github.com/settings/applications)**.
+
+**You can easily [generate it here](https://github.com/settings/applications)**.
+
+And:
+
+- 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"'`
