 Translations
 ------------
 
 Translations for the strings in this project are managed using the online
 [Crowdin platform][crowdin]. To synchronise with Crowdin you can use the build
 script. To get a list of the possible commands type `./build.py help` at
 the command line. (You will also need the Crowdin API key for the project.)

 firstRun.html

 This is the implementation of the Adblock Plus first-run page that will show up
 whenever changes are applied automatically to user's Adblock Plus configuration.
 This will usually happen when the user first installs Adblock Plus (initial
 setup), but it can also happen in case the user's settings get lost.
