+
+> Minify URLs by converting them from absolute to relative.
+
+If you were to use this library on a website like `http://example.com/dir1/dir1-1/`, you would get results such as:
+
+| Before                                      | After                                |
+| :------------------------------------------ | :----------------------------------- |
+| `http://example.com/dir1/dir1-2/index.html` | `../dir1-2/`                         |
+| `http://example.com/dir2/dir2-1/`           | `/dir2/dir2-1/`                      |
+| `http://example.com/dir1/dir1-1/`           | ` `                                  |
+| `https://example.com/dir1/dir1-1/`          | `https://example.com/dir1/dir1-1/`   |
+| `http://google.com:80/dir/`                 | `//google.com/dir/`                  |
+| `../../../../../../../../#anchor`           | `/#anchor`                           |
+
+**All string parsing.** *No* directory browsing. It is thoroughly tested, very fast and lightweight with zero external dependencies.
+
+## Getting Started
+
+This utility requires [Node.js](http://nodejs.org/) `>= 0.10`. To install, type this at the command line:
+```
+npm install relateurl --save-dev
+```
+
+### Options
+
+#### options.defaultPorts
+Type: `Object`   
+Default value: `{ftp:21, http:80, https:443}`  
+
+Extend the list with any ports you need. Any URLs containing these default ports will have them removed. Example: `http://example.com:80/` will become `http://example.com/`.
+
+#### options.directoryIndexes
+Type: `Array`   
+Default value: `["index.html"]`  
+
+Extend the list with any resources you need. Works with [`options.removeDirectoryIndexes`](#options.removeDirectoryIndexes).
+
+#### options.ignore_www
+Type: `Boolean`  
+Default value: `false`  
+
+This will, for example, consider any domains containing `http://www.example.com/` to be related to any that contain `http://example.com/`.
+
+#### options.output
+Type: constant or `String`  
+Choices: `RelateUrl.ABSOLUTE`,`RelateUrl.PATH_RELATIVE`,`RelateUrl.ROOT_RELATIVE`,`RelateUrl.SHORTEST`  
+Choices: `"absolute"`,`"pathRelative"`,`"rootRelative"`,`"shortest"`  
+Default value: `RelateUrl.SHORTEST`  
+
+`RelateUrl.ABSOLUTE` will produce an absolute URL. Overrides [`options.schemeRelative`](#options.schemeRelative) with a value of `false`.  
+`RelateUrl.PATH_RELATIVE` will produce something like `../child-of-parent/etc/`.  
+`RelateUrl.ROOT_RELATIVE` will produce something like `/child-of-root/etc/`.  
+`RelateUrl.SHORTEST` will choose whichever is shortest between root- and path-relative.  
+
+#### options.rejectedSchemes
+Type: `Array`   
+Default value: `["data","javascript","mailto"]`  
+
+Extend the list with any additional schemes. Example: `javascript:something` will not be modified.
+
+#### options.removeAuth
+Type: `Boolean`   
+Default value: `false`  
+
+Remove user authentication information from the output URL.
+
+#### options.removeDirectoryIndexes
+Type: `Boolean`   
+Default value: `true`  
+
+Remove any resources that match any found in [`options.directoryIndexes`](#options.directoryIndexes).
+
+#### options.removeEmptyQueries
+Type: `Boolean`   
+Default value: `false`  
+
+Remove empty query variables. Example: `http://domain.com/?var1&var2=&var3=asdf` will become `http://domain.com/?var3=adsf`. This does not apply to unrelated URLs (with other protocols, auths, hosts and/or ports).
+
+#### options.removeRootTrailingSlash
+Type: `Boolean`   
+Default value: `true`  
+
+Remove trailing slashes from root paths. Example: `http://domain.com/?var` will become `http://domain.com?var` while `http://domain.com/dir/?var` will not be modified.
+
+#### options.schemeRelative
+Type: `Boolean`   
+Default value: `true`  
+
+Output URLs relative to the scheme. Example: `http://example.com/` will become `//example.com/`.
+
+#### options.site
+Type: `String`   
+Default value: `undefined`  
+
+An options-based version of the [`from`](#examples) argument. If both are specified, `from` takes priority.
+
+#### options.slashesDenoteHost
+Type: `Boolean`   
+Default value: `true`  
+
+Passed to Node's [`url.parse`](http://nodejs.org/api/url.html#url_url_parse_urlstr_parsequerystring_slashesdenotehost).
+
+### Examples
+This library can be used as a [function for single-use](#single-instance) or as a [class for multiple conversions](#reusable-instances).
+
+Upon successful conversion, a `String` will be returned. If an issue is encountered while parsing `from`, an error will be thrown.
+
+#### Single Instance
+```js
+var RelateUrl = require("relateurl");
+
+var result = RelateUrl.relate(from, to, options);
+```
+
+#### Reusable Instances
+```js
+var RelateUrl = require("relateurl");
+
+var instance = new RelateUrl(from, options);
+
+var result1 = instance.relate(to1);
+var result2 = instance.relate(to2, customOptions);
+var result3 = instance.relate(to3);
+```
+
+## FAQ
+1. **Why bother writing/using this?**  
+To aid in further minifying HTML, mainly for the purpose of faster page loads and SEO. It's been integrated into [HTMLMinifier](https://github.com/kangax/html-minifier).
+
+2. **Why not just use Node's `url.parse`, `url.resolve` and `path.relative`?**  
+`url.parse` *is* used, but `url.resolve` and `path.relative` are both slower and less powerful than this library.
+
