 * **Name of the binary file:**  
   The binary file of the browser, ``peb``, ``peb.app``, ``peb.dmg`` or ``peb.exe`` by default, can be renamed without restrictions. It can take the name of the PEB-based application it is going to run. No additional adjustments are necessary after renaming the binary. If log files are wanted, they will take the name of the binary file (without the filename extension), whatever the name may be.
 * **Application directory:**  
-  Application directory is ``{PEB_binary_directory}/resources/app``. All files used by PEB, with the exception of data files, must be located within this folder. Application directory is hard-coded in C++ code for compatibility with the [Electron](http://electron.atom.io/) framework.   [Epigraphista](https://github.com/ddmitov/epigraphista) provides an example of a PEB-based application, that is also compatible with [Electron](http://electron.atom.io/) and [NW.js](http://nwjs.io/).

   Note, however, that to achieve [Electron](http://electron.atom.io/) and [NW.js](http://nwjs.io/) compatibility a PEB-based program must fit into the single-page application paradigm and no frames or iframes should be used.
 * **Data directory:**  
   Data directory is not hard-coded in C++ code, but a separation of data files from code is generally a good practice. Data directory should contain any SQLite or flat file database or other data files, that a PEB-based application is going to use or produce. The recommended path for data directory is inside the ``{PEB_binary_directory}/resources`` directory. ``data`` is a good directory name, although not mandatory. Perl scripts can access this folder using the following code:
