+# Mime
+
+A comprehensive, compact MIME type module.
+
+[![Build Status](https://travis-ci.org/broofa/node-mime.svg?branch=master)](https://travis-ci.org/broofa/node-mime)
+
+## Version 2 Notes
+
+Version 2 is a breaking change from 1.x as the semver implies.  Specifically:
+
+* `lookup()` renamed to `getType()`
+* `extension()` renamed to `getExtension()`
+* `charset()` and `load()` methods have been removed
+
+If you prefer the legacy version of this module please `npm install mime@^1`.  Version 1 docs may be found [here](https://github.com/broofa/node-mime/tree/v1.4.0).
+
+## Install
+
+### NPM
+```
+npm install mime
+```
+
+### Browser
+
+It is recommended that you use a bundler such as
+[webpack](https://webpack.github.io/) or [browserify](http://browserify.org/) to
+package your code.  However, browser-ready versions are available via wzrd.in.
+E.g. For the full version:
+
+    <script src="https://wzrd.in/standalone/mime@latest"></script>
+    <script>
+    mime.getType(...); // etc.
+    <script>
+
+Or, for the `mime/lite` version:
+
+    <script src="https://wzrd.in/standalone/mime%2flite@latest"></script>
+    <script>
+    mimelite.getType(...); // (Note `mimelite` here)
+    <script>
+
+## Quick Start
+
+For the full version (800+ MIME types, 1,000+ extensions):
+
+```javascript --run default
+const mime = require('mime');
+
+mime.getType('txt');                    // RESULT
+mime.getExtension('text/plain');        // RESULT
+```
+
+See [Mime API](#mime-api) below for API details.
+
+## Lite Version
+
+There is also a "lite" version of this module that omits vendor-specific
+(`*/vnd.*`) and experimental (`*/x-*`) types.  It weighs in at ~2.5KB, compared
+to 8KB for the full version.  To load the lite version:
+
+```javascript
+const mime = require('mime/lite');
+```
+
+## Mime .vs. mime-types .vs. mime-db modules
+
+For those of you wondering about the difference between these [popular] NPM modules,
+here's a brief rundown ...
+
+[`mime-db`](https://github.com/jshttp/mime-db) is "the source of
+truth" for MIME type information.  It is not an API.  Rather, it is a canonical
+dataset of mime type definitions pulled from IANA, Apache, NGINX, and custom mappings
+submitted by the Node.js community.
+
+[`mime-types`](https://github.com/jshttp/mime-types) is a thin
+wrapper around mime-db that provides an API drop-in compatible(ish) with `mime @ < v1.3.6` API.
+
+`mime` is, as of v2, a self-contained module bundled with a pre-optimized version
+of the `mime-db` dataset.  It provides a simplified API with the following characteristics:
+
+* Intelligently resolved type conflicts (See [mime-score](https://github.com/broofa/mime-score) for details)
+* Method naming consistent with industry best-practices
+* Compact footprint.  E.g. The minified+compressed sizes of the various modules:
+
+Module | Size
+--- | ---
+`mime-db`  | 18 KB
+`mime-types` | same as mime-db
+`mime` | 8 KB
+`mime/lite` | 2 KB
+
+## Mime API
+
+Both `require('mime')` and `require('mime/lite')` return instances of the MIME
+class, documented below.
+
+### new Mime(typeMap, ... more maps)
+
+Most users of this module will not need to create Mime instances directly.
+However if you would like to create custom mappings, you may do so as follows
+...
+
+```javascript --run default
+// Require Mime class
+const Mime = require('mime/Mime');
+
+// Define mime type -> extensions map
+const typeMap = {
+  'text/abc': ['abc', 'alpha', 'bet'],
+  'text/def': ['leppard']
+};
+
+// Create and use Mime instance
+const myMime = new Mime(typeMap);
+myMime.getType('abc');            // RESULT
+myMime.getExtension('text/def');  // RESULT
+```
+
+If more than one map argument is provided, each map is `define()`ed (see below), in order.
+
+### mime.getType(pathOrExtension)
+
+Get mime type for the given path or extension.  E.g.
+
+```javascript --run default
+mime.getType('js');             // RESULT
+mime.getType('json');           // RESULT
+
+mime.getType('txt');            // RESULT
+mime.getType('dir/text.txt');   // RESULT
+mime.getType('dir\\text.txt');  // RESULT
+mime.getType('.text.txt');      // RESULT
+mime.getType('.txt');           // RESULT
+```
+
+`null` is returned in cases where an extension is not detected or recognized
+
+```javascript --run default
+mime.getType('foo/txt');        // RESULT
+mime.getType('bogus_type');     // RESULT
+```
+
+### mime.getExtension(type)
+Get extension for the given mime type.  Charset options (often included in
+Content-Type headers) are ignored.
+
+```javascript --run default
+mime.getExtension('text/plain');               // RESULT
+mime.getExtension('application/json');         // RESULT
+mime.getExtension('text/html; charset=utf8');  // RESULT
+```
+
+### mime.define(typeMap[, force = false])
+
+Define [more] type mappings.
+
+`typeMap` is a map of type -> extensions, as documented in `new Mime`, above.
+
+By default this method will throw an error if you try to map a type to an
+extension that is already assigned to another type.  Passing `true` for the
+`force` argument will suppress this behavior (overriding any previous mapping).
+
+```javascript --run default
+mime.define({'text/x-abc': ['abc', 'abcd']});
+
+mime.getType('abcd');            // RESULT
+mime.getExtension('text/x-abc')  // RESULT
+```
+
+## Command Line
+
+    mime [path_or_extension]
+
+E.g.
+
+    > mime scripts/jquery.js
+    application/javascript
