 Adblock Plus for Chrome, Opera, Microsoft Edge and Firefox
 ==========================================================
 
 This repository contains the platform-specific Adblock Plus source code for
 Chrome, Opera, Microsoft Edge and Firefox. It can be used to build
 Adblock Plus for these platforms, generic Adblock Plus code will be extracted
 from other repositories automatically (see _dependencies_ file).
 
 Note that the Firefox extension built from this repository is the new
 [WebExtension](https://developer.mozilla.org/en-US/Add-ons/WebExtensions).
 The source code of the legacy Adblock Plus extension
 can be found [here](https://hg.adblockplus.org/adblockplus).

Just wondering, are these extra whitespaces intentional?

[Sebastian Noack, 2018/04/15 12:01:17]

Yes, in order to group the Python modules under Python.

+  - For signed builds: [PyCrypto module](https://www.dlitz.net/software/pycrypto/)
+- [Node.js](https://nodejs.org/) (>= 8)

Version 8.x is the current LTS channel of Node.js. I'm on version 8.5.0 which
buildtools is compatible with. If any of you have any more accurate information
regarding the minimum Node.js version required, please let me know.

[Sebastian Noack, 2018/04/16 08:27:35]

As discussed with Dave on IRC, I went with Node.js >=7 now.
For reference, this is what we require for adblockpluscore.

 
 ### Building the extension
 
 Run one of the following commands in the project directory, depending on your
 target platform:
 
     ./build.py build -t chrome -k adblockpluschrome.pem
     ./build.py build -t edge
     ./build.py build -t gecko

 Linting
 -------
 
 You can lint the code using [ESLint](http://eslint.org).
 
     eslint *.js lib/ qunit/ ext/ chrome/
 
 You will need to set up ESLint and our configuration first, see
 [eslint-config-eyeo](https://hg.adblockplus.org/codingtools/file/tip/eslint-config-eyeo)
 for more information.
