+
+> Links recognition library with FULL unicode support.
+> Focused on high quality link patterns detection in plain text.
+
+__[Demo](http://markdown-it.github.io/linkify-it/)__
+
+Why it's awesome:
+
+- Full unicode support, _with astral characters_!
+- International domains support.
+- Allows rules extension & custom normalizers.
+
+
+Install
+-------
+
+```bash
+npm install linkify-it --save
+```
+
+Browserification is also supported.
+
+
+Usage examples
+--------------
+
+##### Example 1
+
+```js
+import linkifyit from 'linkify-it';
+const linkify = linkifyit();
+
+// Reload full tlds list & add unofficial `.onion` domain.
+linkify
+  .tlds(require('tlds'))          // Reload with full tlds list
+  .tlds('onion', true)            // Add unofficial `.onion` domain
+  .add('git:', 'http:')           // Add `git:` protocol as "alias"
+  .add('ftp:', null)              // Disable `ftp:` protocol
+  .set({ fuzzyIP: true });        // Enable IPs in fuzzy links (without schema)
+
+console.log(linkify.test('Site github.com!'));  // true
+
+console.log(linkify.match('Site github.com!')); // [ {
+                                                //   schema: "",
+                                                //   index: 5,
+                                                //   lastIndex: 15,
+                                                //   raw: "github.com",
+                                                //   text: "github.com",
+                                                //   url: "http://github.com",
+                                                // } ]
+```
+
+##### Example 2. Add twitter mentions handler
+
+```js
+linkify.add('@', {
+  validate: function (text, pos, self) {
+    const tail = text.slice(pos);
+
+    if (!self.re.twitter) {
+      self.re.twitter =  new RegExp(
+        '^([a-zA-Z0-9_]){1,15}(?!_)(?=$|' + self.re.src_ZPCc + ')'
+      );
+    }
+    if (self.re.twitter.test(tail)) {
+      // Linkifier allows punctuation chars before prefix,
+      // but we additionally disable `@` ("@@mention" is invalid)
+      if (pos >= 2 && tail[pos - 2] === '@') {
+        return false;
+      }
+      return tail.match(self.re.twitter)[0].length;
+    }
+    return 0;
+  },
+  normalize: function (match) {
+    match.url = 'https://twitter.com/' + match.url.replace(/^@/, '');
+  }
+});
+```

+
+API
+---
+
+__[API documentation](http://markdown-it.github.io/linkify-it/doc)__
+
+### new LinkifyIt(schemas, options)
+
+Creates new linkifier instance with optional additional schemas.
+Can be called without `new` keyword for convenience.
+
+By default understands:
+
+- `http(s)://...` , `ftp://...`, `mailto:...` & `//...` links
+- "fuzzy" links and emails (google.com, foo@bar.com).
+
+`schemas` is an object, where each key/value describes protocol/rule:
+
+- __key__ - link prefix (usually, protocol name with `:` at the end, `skype:`
+  for example). `linkify-it` makes sure that prefix is not preceded with
+  alphanumeric char.
+- __value__ - rule to check tail after link prefix
+  - _String_ - just alias to existing rule
+  - _Object_
+    - _validate_ - either a `RegExp` (start with `^`, and don't include the
+      link prefix itself), or a validator function which, given arguments
+      _text_, _pos_, and _self_, returns the length of a match in _text_
+      starting at index _pos_.  _pos_ is the index right after the link prefix.
+      _self_ can be used to access the linkify object to cache data.
+    - _normalize_ - optional function to normalize text & url of matched result
+      (for example, for twitter mentions).
+
+`options`:
+
+- __fuzzyLink__ - recognize URL-s without `http(s)://` head. Default `true`.
+- __fuzzyIP__ - allow IPs in fuzzy links above. Can conflict with some texts
+  like version numbers. Default `false`.
+- __fuzzyEmail__ - recognize emails without `mailto:` prefix. Default `true`.
+- __---__ - set `true` to terminate link with `---` (if it's considered as long dash).
+
+
+### .test(text)
+
+Searches linkifiable pattern and returns `true` on success or `false` on fail.
+
+
+### .pretest(text)
+
+Quick check if link MAY BE can exist. Can be used to optimize more expensive
+`.test()` calls. Return `false` if link can not be found, `true` - if `.test()`
+call needed to know exactly.
+
+
+### .testSchemaAt(text, name, offset)
+
+Similar to `.test()` but checks only specific protocol tail exactly at given
+position. Returns length of found pattern (0 on fail).
+
+
+### .match(text)
+
+Returns `Array` of found link matches or null if nothing found.
+
+Each match has:
+
+- __schema__ - link schema, can be empty for fuzzy links, or `//` for
+  protocol-neutral  links.
+- __index__ - offset of matched text
+- __lastIndex__ - index of next char after mathch end
+- __raw__ - matched text
+- __text__ - normalized text
+- __url__ - link, generated from matched text
+
+
+### .matchAtStart(text)
+
+Checks if a match exists at the start of the string. Returns `Match`
+(see docs for `match(text)`) or null if no URL is at the start.
+Doesn't work with fuzzy links.
+
+
+### .tlds(list[, keepOld])
+
+Load (or merge) new tlds list. Those are needed for fuzzy links (without schema)
+to avoid false positives. By default:
+
+- 2-letter root zones are ok.
+- biz|com|edu|gov|net|org|pro|web|xxx|aero|asia|coop|info|museum|name|shop|рф are ok.
+- encoded (`xn--...`) root zones are ok.
+
+If that's not enough, you can reload defaults with more detailed zones list.
+
+### .add(key, value)
+
+Add a new schema to the schemas object.  As described in the constructor
+definition, `key` is a link prefix (`skype:`, for example), and `value`
+is a String to alias to another schema, or an Object with `validate` and
+optionally `normalize` definitions.  To disable an existing rule, use
+`.add(key, null)`.
+
+
+### .set(options)
+
+Override default options. Missed properties will not be changed.
