+# SingleFile (MAFF to HTML)
+
+## Introduction
+
+SingleFile can be launched from the command line to convert MAFF files into HTML files by running it into Firefox. It runs through Node.js as a standalone script injected into the web page instead of being embedded into a WebExtension. To connect to Firefox, it uses [Selenium WebDriver](https://www.npmjs.com/package/selenium-webdriver).
+
+## Convert MAFF to HTML
+
+### Prerequisites
+
+- [Node.js](https://nodejs.org) must be installed. 
+- You must use specific versions of Firefox and Selenium WebDriver component. You must install respectively [Firefox version 56.0.2](https://ftp.mozilla.org/pub/firefox/releases/56.0.2/) and [Mozilla geckodriver version 0.20.1](https://github.com/mozilla/geckodriver/releases/tag/v0.20.1).
+- It is recommended that the Firefox binary can be found through the `PATH` environment variable or the current folder. Otherwise you will need to set the `--browser-executable-path` option..
+- It is also recommended that the Mozilla geckodriver binary can be found through the `PATH` environment variable or the current folder. Otherwise you will need to set the `--web-driver-executable-path` option.
+
+### Install
+
+- Unzip the [master archive](https://github.com/gildas-lormeau/SingleFile/archive/master.zip) somewhere on your disk in an empty folder.
+
+  `$ unzip master.zip .`
+  
+- Go into the `maff2html` directory.
+
+  `$ cd maff2html`
+  
+- Install dependencies with npm (installed with Node.js).
+
+  `$ npm install`
+  
+- Make `single-file.js` executable (Linux/Unix/BSD etc.).
+
+  `$ chmod +x single-file.js`
+
+### Run
+
+- Syntax
+ 
+  `$ ./single-file.js <url> [output] [options ...]` (Linux/Unix/BSD etc.)
+
+  `> node single-file.js <url> [output] [options ...]` (Windows)    
+
+- Display help
+
+  `$ ./single-file.js --help` (Linux/Unix/BSD etc.)
+
+  `> node single-file.js --help` (Windows)
+
+- Examples
+
+  - Convert a MAFF file (e.g. `wikipedia.maff`) into `wikipedia.html` with Firefox installed in the folder "~/firefox-56.0.2/" (Linux/Unix/BSD etc.) or "C:\Program Files\Mozilla Firefox 56.0.2\" (Windows)
+
+  `$ ./single-file.js file:///home/gildas/wikipedia.maff wikipedia.html --browser-executable-path=~/firefox-56.0.2/firefox` (Linux/Unix/BSD etc.)
+  
+  `> node single-file.js file:///C:/Users/Gildas/wikipedia.maff wikipedia.html --browser-executable-path="C:\Program Files\Mozilla Firefox 56.0.2\firefox"` (Windows)
