+
+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator). Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
+
+In addition to negotiator, it allows:
+
+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])` as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## Installation
+
+```sh
+npm install accepts
+```
+
+## API
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+
+## Examples
+
+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app(req, res) {
+ var accept = accepts(req)
+
+ // the order of this list is significant; should be server preferred order
+ switch(accept.type(['json', 'html'])) {
+ case 'json':
+ res.setHeader('Content-Type', 'application/json')
+ res.write('{"hello":"world!"}')
+ break
+ case 'html':
+ res.setHeader('Content-Type', 'text/html')
+ res.write('hello, world!')
+ break
+ default:
+ // the fallback is text/plain, so no need to specify it above
+ res.setHeader('Content-Type', 'text/plain')
+ res.write('hello, world!')
+ break
+ }
+
+ res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```

+## 4.0.11 (2017-02-07)
+
+### Bug fixes
+
+Allow all forms of member expressions to be parenthesized as lvalue.
+
+## 4.0.10 (2017-02-07)
+
+### Bug fixes
+
+Don't expect semicolons after default-exported functions or classes,
+even when they are expressions.
+
+Check for use of `'use strict'` directives in non-simple parameter
+functions, even when already in strict mode.
+
+## 4.0.9 (2017-02-06)
+
+### Bug fixes
+
+Fix incorrect error raised for parenthesized simple assignment
+targets, so that `(x) = 1` parses again.
+
+## 4.0.8 (2017-02-03)
+
+### Bug fixes
+
+Solve spurious parenthesized pattern errors by temporarily erring on
+the side of accepting programs that our delayed errors don't handle
+correctly yet.
+
+## 4.0.7 (2017-02-02)
+
+### Bug fixes
+
+Accept invalidly rejected code like `(x).y = 2` again.
+
+Don't raise an error when a function _inside_ strict code has a
+non-simple parameter list.
+
+## 4.0.6 (2017-02-02)
+
+### Bug fixes
+
+Fix exponential behavior (manifesting itself as a complete hang for
+even relatively small source files) introduced by the new 'use strict'
+check.
+
+## 4.0.5 (2017-02-02)
+
+### Bug fixes
+
+Disallow parenthesized pattern expressions.
+
+Allow keywords as export names.
+
+Don't allow the `async` keyword to be parenthesized.
+
+Properly raise an error when a keyword contains a character escape.
+
+Allow `"use strict"` to appear after other string literal expressions.
+
+Disallow labeled declarations.
+
+## 4.0.4 (2016-12-19)
+
+### Bug fixes
+
+Fix issue with loading acorn_loose.js with an AMD loader.
+
+Fix crash when `export` was followed by a keyword that can't be
+exported.
+
+## 4.0.3 (2016-08-16)
+
+### Bug fixes
+
+Allow regular function declarations inside single-statement `if`
+branches in loose mode. Forbid them entirely in strict mode.
+
+Properly parse properties named `async` in ES2017 mode.
+
+Fix bug where reserved words were broken in ES2017 mode.
+
+## 4.0.2 (2016-08-11)
+
+### Bug fixes
+
+Don't ignore period or 'e' characters after octal numbers.
+
+Fix broken parsing for call expressions in default parameter values
+of arrow functions.
+
+## 4.0.1 (2016-08-08)
+
+### Bug fixes
+
+Fix false positives in duplicated export name errors.
+
+## 4.0.0 (2016-08-07)
+
+### Breaking changes
+
+The default `ecmaVersion` option value is now 7.
+
+A number of internal method signatures changed, so plugins might need
+to be updated.
+
+### Bug fixes
+
+The parser now raises errors on duplicated export names.
+
+`arguments` and `eval` can now be used in shorthand properties.
+
+Duplicate parameter names in non-simple argument lists now always
+produce an error.
+
+### New features
+
+The `ecmaVersion` option now also accepts year-style version numbers
+(2015, etc).
+
+Support for `async`/`await` syntax when `ecmaVersion` is >= 8.
+
+Support for trailing commas in call expressions when `ecmaVersion`
+is >= 8.
+
+## 3.3.0 (2016-07-25)
+
+### Bug fixes
+
+Fix bug in tokenizing of regexp operator after a function declaration.
+
+Fix parser crash when parsing an array pattern with a hole.
+
+### New features
+
+Implement check against complex argument lists in functions that
+enable strict mode in ES7.
+
+## 3.2.0 (2016-06-07)
+
+### Bug fixes
+
+Improve handling of lack of unicode regexp support in host
+environment.
+
+Properly reject shorthand properties whose name is a keyword.
+
+Don't crash when the loose parser is called without options object.
+
+### New features
+
+Visitors created with `visit.make` now have their base as _prototype_,
+rather than copying properties into a fresh object.
+
+Make it possible to use `visit.ancestor` with a walk state.
+
+## 3.1.0 (2016-04-18)
+
+### Bug fixes
+
+Fix issue where the loose parser created invalid TemplateElement nodes
+for unclosed template literals.
+
+Properly tokenize the division operator directly after a function
+expression.
+
+Allow trailing comma in destructuring arrays.
+
+### New features
+
+The walker now allows defining handlers for `CatchClause` nodes.
+
+## 3.0.4 (2016-02-25)
+
+### Fixes
+
+Allow update expressions as left-hand-side of the ES7 exponential
+operator.
+
+## 3.0.2 (2016-02-10)
+
+### Fixes
+
+Fix bug that accidentally made `undefined` a reserved word when
+parsing ES7.
+
+## 3.0.0 (2016-02-10)
+
+### Breaking changes
+
+The default value of the `ecmaVersion` option is now 6 (used to be 5).
+
+Support for comprehension syntax (which was dropped from the draft
+spec) has been removed.
+
+### Fixes
+
+`let` and `yield` are now “contextual keywords”, meaning you can
+mostly use them as identifiers in ES5 non-strict code.
+
+A parenthesized class or function expression after `export default` is
+now parsed correctly.
+
+### New features
+
+When `ecmaVersion` is set to 7, Acorn will parse the exponentiation
+operator (`**`).
+
+The identifier character ranges are now based on Unicode 8.0.0.
+
+Plugins can now override the `raiseRecoverable` method to override the
+way non-critical errors are handled.
+
+## 2.7.0 (2016-01-04)
+
+### Fixes
+
+Stop allowing rest parameters in setters.
+
+Make sure the loose parser always attaches a `local` property to
+`ImportNamespaceSpecifier` nodes.
+
+Disallow `y` rexexp flag in ES5.
+
+Disallow `\00` and `\000` escapes in strict mode.
+
+Raise an error when an import name is a reserved word.
+
+## 2.6.4 (2015-11-12)
+
+### Fixes
+
+Fix crash in loose parser when parsing invalid object pattern.
+
+### New features
+
+Support plugins in the loose parser.
+
+## 2.6.2 (2015-11-10)
+
+### Fixes
+
+Don't crash when no options object is passed.
+
+## 2.6.0 (2015-11-09)
+
+### Fixes
+
+Add `await` as a reserved word in module sources.
+
+Disallow `yield` in a parameter default value for a generator.
+
+Forbid using a comma after a rest pattern in an array destructuring.
+
+### New features
+
+Support parsing stdin in command-line tool.
+
+## 2.5.2 (2015-10-27)
+
+### Fixes
+
+Fix bug where the walker walked an exported `let` statement as an
+expression.
+
+## 2.5.0 (2015-10-27)
+
+### Fixes
+
+Fix tokenizer support in the command-line tool.
+
+In the loose parser, don't allow non-string-literals as import
+sources.
+
+Stop allowing `new.target` outside of functions.
+
+Remove legacy `guard` and `guardedHandler` properties from try nodes.
+
+Stop allowing multiple `__proto__` properties on an object literal in
+strict mode.
+
+Don't allow rest parameters to be non-identifier patterns.
+
+Check for duplicate paramter names in arrow functions.

+When run in a CommonJS (node.js) or AMD environment, exported values
+appear in the interfaces exposed by the individual files, as usual.
+When loaded in the browser (Acorn works in any JS-enabled browser more
+recent than IE5) without any kind of module management, a single
+global object `acorn` will be defined, and all the exported properties
+will be added to that.
+
+### Main parser
+
+This is implemented in `dist/acorn.js`, and is what you get when you
+`require("acorn")` in node.js.
+
+**parse**`(input, options)` is used to parse a JavaScript program.
+The `input` parameter is a string, `options` can be undefined or an
+object setting some of the options listed below. The return value will
+be an abstract syntax tree object as specified by the
+[ESTree spec][estree].
+
+When encountering a syntax error, the parser will raise a
+`SyntaxError` object with a meaningful message. The error object will
+have a `pos` property that indicates the character offset at which the
+error occurred, and a `loc` object that contains a `{line, column}`
+object referring to that same position.
+
+[estree]: https://github.com/estree/estree
+
+- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be
+ either 3, 5, 6 (2015), 7 (2016), or 8 (2017). This influences support for strict
+ mode, the set of reserved words, and support for new syntax features.
+ Default is 7.
+
+ **NOTE**: Only 'stage 4' (finalized) ECMAScript features are being
+ implemented by Acorn.
+
+- **sourceType**: Indicate the mode the code should be parsed in. Can be
+ either `"script"` or `"module"`. This influences global strict mode
+ and parsing of `import` and `export` declarations.
+
+- **onInsertedSemicolon**: If given a callback, that callback will be
+ called whenever a missing semicolon is inserted by the parser. The
+ callback will be given the character offset of the point where the
+ semicolon is inserted as argument, and if `locations` is on, also a
+ `{line, column}` object representing this position.
+
+- **onTrailingComma**: Like `onInsertedSemicolon`, but for trailing
+ commas.
+
+- **allowReserved**: If `false`, using a reserved word will generate
+ an error. Defaults to `true` for `ecmaVersion` 3, `false` for higher
+ versions. When given the value `"never"`, reserved words and
+ keywords can also not be used as property names (as in Internet
+ Explorer's old parser).
+
+- **allowReturnOutsideFunction**: By default, a return statement at
+ the top level raises an error. Set this to `true` to accept such
+ code.
+
+- **allowImportExportEverywhere**: By default, `import` and `export`
+ declarations can only appear at a program's top level. Setting this
+ option to `true` allows them anywhere where a statement is allowed.
+
+- **allowHashBang**: When this is enabled (off by default), if the
+ code starts with the characters `#!` (as in a shellscript), the
+ first line will be treated as a comment.
+
+- **locations**: When `true`, each node has a `loc` object attached
+ with `start` and `end` subobjects, each of which contains the
+ one-based line and zero-based column numbers in `{line, column}`
+ form. Default is `false`.
+
+- **onToken**: If a function is passed for this option, each found
+ token will be passed in same format as tokens returned from
+ `tokenizer().getToken()`.
+
+ If array is passed, each found token is pushed to it.
+
+ Note that you are not allowed to call the parser from the
+ callback—that will corrupt its internal state.
+
+- **onComment**: If a function is passed for this option, whenever a
+ comment is encountered the function will be called with the
+ following parameters:
+
+ - `block`: `true` if the comment is a block comment, false if it
+ is a line comment.
+ - `text`: The content of the comment.
+ - `start`: Character offset of the start of the comment.
+ - `end`: Character offset of the end of the comment.
+
+ When the `locations` options is on, the `{line, column}` locations
+ of the comment’s start and end are passed as two additional
+ parameters.
+
+ If array is passed for this option, each found comment is pushed
+ to it as object in Esprima format:
+
+ ```javascript
+ {
+ "type": "Line" | "Block",
+ "value": "comment text",
+ "start": Number,
+ "end": Number,
+ // If `locations` option is on:
+ "loc": {
+ "start": {line: Number, column: Number}
+ "end": {line: Number, column: Number}
+ },
+ // If `ranges` option is on:
+ "range": [Number, Number]
+ }
+ ```
+
+ Note that you are not allowed to call the parser from the
+ callback—that will corrupt its internal state.
+
+- **ranges**: Nodes have their start and end characters offsets
+ recorded in `start` and `end` properties (directly on the node,
+ rather than the `loc` object, which holds line/column data. To also
+ add a [semi-standardized][range] `range` property holding a
+ `[start, end]` array with the same numbers, set the `ranges` option
+ to `true`.
+
+- **program**: It is possible to parse multiple files into a single
+ AST by passing the tree produced by parsing the first file as the
+ `program` option in subsequent parses. This will add the toplevel
+ forms of the parsed file to the "Program" (top) node of an existing
+ parse tree.
+
+- **sourceFile**: When the `locations` option is `true`, you can pass
+ this option to add a `source` attribute in every node’s `loc`
+ object. Note that the contents of this option are not examined or
+ processed in any way; you are free to use whatever format you
+ choose.
+
+- **directSourceFile**: Like `sourceFile`, but a `sourceFile` property
+ will be added (regardless of the `location` option) directly to the
+ nodes, rather than the `loc` object.
+
+- **preserveParens**: If this option is `true`, parenthesized expressions
+ are represented by (non-standard) `ParenthesizedExpression` nodes
+ that have a single `expression` property containing the expression
+ inside parentheses.
+
+[range]: https://bugzilla.mozilla.org/show_bug.cgi?id=745678
+
+**parseExpressionAt**`(input, offset, options)` will parse a single
+expression in a string, and return its AST. It will not complain if
+there is more of the string left after the expression.
+
+**getLineInfo**`(input, offset)` can be used to get a `{line,
+column}` object for a given program string and character offset.
+
+**tokenizer**`(input, options)` returns an object with a `getToken`
+method that can be called repeatedly to get the next token, a `{start,
+end, type, value}` object (with added `loc` property when the
+`locations` option is enabled and `range` property when the `ranges`
+option is enabled). When the token's type is `tokTypes.eof`, you
+should stop calling the method, since it will keep returning that same
+token forever.
+
+In ES6 environment, returned result can be used as any other
+protocol-compliant iterable:
+
+```javascript
+for (let token of acorn.tokenizer(str)) {
+ // iterate over the tokens
+}
+
+// transform code to array of tokens:
+var tokens = [...acorn.tokenizer(str)];
+```
+
+**tokTypes** holds an object mapping names to the token type objects
+that end up in the `type` properties of tokens.
+
+#### Note on using with [Escodegen][escodegen]
+
+Escodegen supports generating comments from AST, attached in
+Esprima-specific format. In order to simulate same format in
+Acorn, consider following example:
+
+```javascript
+var comments = [], tokens = [];
+
+var ast = acorn.parse('var x = 42; // answer', {
+ // collect ranges for each node
+ ranges: true,
+ // collect comments in Esprima's format
+ onComment: comments,
+ // collect token ranges
+ onToken: tokens
+});
+
+// attach comments using collected information
+escodegen.attachComments(ast, comments, tokens);
+
+// generate code
+console.log(escodegen.generate(ast, {comment: true}));
+// > 'var x = 42; // answer'
+```

+
+### dist/acorn_loose.js ###
+
+This file implements an error-tolerant parser. It exposes a single
+function. The loose parser is accessible in node.js via `require("acorn/dist/acorn_loose")`.
+
+**parse_dammit**`(input, options)` takes the same arguments and
+returns the same syntax tree as the `parse` function in `acorn.js`,
+but never raises an error, and will do its best to parse syntactically
+invalid code in as meaningful a way as it can. It'll insert identifier
+nodes with name `"✖"` as placeholders in places where it can't make
+sense of the input. Depends on `acorn.js`, because it uses the same
+tokenizer.
+
+### dist/walk.js ###
+
+Implements an abstract syntax tree walker. Will store its interface in
+`acorn.walk` when loaded without a module system.
+
+**simple**`(node, visitors, base, state)` does a 'simple' walk over
+a tree. `node` should be the AST node to walk, and `visitors` an
+object with properties whose names correspond to node types in the
+[ESTree spec][estree]. The properties should contain functions
+that will be called with the node object and, if applicable the state
+at that point. The last two arguments are optional. `base` is a walker
+algorithm, and `state` is a start state. The default walker will
+simply visit all statements and expressions and not produce a
+meaningful state. (An example of a use of state is to track scope at
+each point in the tree.)
+
+**ancestor**`(node, visitors, base, state)` does a 'simple' walk over
+a tree, building up an array of ancestor nodes (including the current node)
+and passing the array to the callbacks as a third parameter.
+
+**recursive**`(node, state, functions, base)` does a 'recursive'
+walk, where the walker functions are responsible for continuing the
+walk on the child nodes of their target node. `state` is the start
+state, and `functions` should contain an object that maps node types
+to walker functions. Such functions are called with `(node, state, c)`
+arguments, and can cause the walk to continue on a sub-node by calling
+the `c` argument on it with `(node, state)` arguments. The optional
+`base` argument provides the fallback walker functions for node types
+that aren't handled in the `functions` object. If not given, the
+default walkers will be used.
+
+**make**`(functions, base)` builds a new walker object by using the
+walker functions in `functions` and filling in the missing ones by
+taking defaults from `base`.
+
+**findNodeAt**`(node, start, end, test, base, state)` tries to
+locate a node in a tree at the given start and/or end offsets, which
+satisfies the predicate `test`. `start` and `end` can be either `null`
+(as wildcard) or a number. `test` may be a string (indicating a node
+type) or a function that takes `(nodeType, node)` arguments and
+returns a boolean indicating whether this node is interesting. `base`
+and `state` are optional, and can be used to specify a custom walker.
+Nodes are tested from inner to outer, so if two nodes match the
+boundaries, the inner one will be preferred.
+
+**findNodeAround**`(node, pos, test, base, state)` is a lot like
+`findNodeAt`, but will match any node that exists 'around' (spanning)
+the given position.
+
+**findNodeAfter**`(node, pos, test, base, state)` is similar to
+`findNodeAround`, but will match all nodes *after* the given position
+(testing outer nodes before inner nodes).
+
+## Command line interface
+
+The `bin/acorn` utility can be used to parse a file from the command
+line. It accepts as arguments its input file and the following
+options:
+
+- `--ecma3|--ecma5|--ecma6|--ecma7`: Sets the ECMAScript version to parse. Default is
+ version 5.
+
+- `--module`: Sets the parsing mode to `"module"`. Is set to `"script"` otherwise.
+
+- `--locations`: Attaches a "loc" object to each node with "start" and
+ "end" subobjects, each of which contains the one-based line and
+ zero-based column numbers in `{line, column}` form.
+
+- `--allow-hash-bang`: If the code starts with the characters #! (as in a shellscript), the first line will be treated as a comment.
+
+- `--compact`: No whitespace is used in the AST output.
+
+- `--silent`: Do not output the AST, just return the exit status.
+
+- `--help`: Print the usage information and quit.
+
+The utility spits out the syntax tree as JSON data.
+
+## Build system
+
+Acorn is written in ECMAScript 6, as a set of small modules, in the
+project's `src` directory, and compiled down to bigger ECMAScript 3
+files in `dist` using [Browserify](http://browserify.org) and
+[Babel](http://babeljs.io/). If you are already using Babel, you can
+consider including the modules directly.
+
+The command-line test runner (`npm test`) uses the ES6 modules. The
+browser-based test page (`test/index.html`) uses the compiled modules.
+The `bin/build-acorn.js` script builds the latter from the former.
+
+If you are working on Acorn, you'll probably want to try the code out
+directly, without an intermediate build step. In your scripts, you can
+register the Babel require shim like this:
+
+ require("babel-core/register")
+
+That will allow you to directly `require` the ES6 modules.
+
+## Plugins
+
+Acorn is designed support allow plugins which, within reasonable
+bounds, redefine the way the parser works. Plugins can add new token
+types and new tokenizer contexts (if necessary), and extend methods in
+the parser object. This is not a clean, elegant API—using it requires
+an understanding of Acorn's internals, and plugins are likely to break
+whenever those internals are significantly changed. But still, it is
+_possible_, in this way, to create parsers for JavaScript dialects
+without forking all of Acorn. And in principle it is even possible to
+combine such plugins, so that if you have, for example, a plugin for
+parsing types and a plugin for parsing JSX-style XML literals, you
+could load them both and parse code with both JSX tags and types.
+
+A plugin should register itself by adding a property to
+`acorn.plugins`, which holds a function. Calling `acorn.parse`, a
+`plugins` option can be passed, holding an object mapping plugin names
+to configuration values (or just `true` for plugins that don't take
+options). After the parser object has been created, the initialization
+functions for the chosen plugins are called with `(parser,
+configValue)` arguments. They are expected to use the `parser.extend`
+method to extend parser methods. For example, the `readToken` method
+could be extended like this:
+
+```javascript
+parser.extend("readToken", function(nextMethod) {
+ return function(code) {
+ console.log("Reading a token!")
+ return nextMethod.call(this, code)
+ }
+})
+```
+
+The `nextMethod` argument passed to `extend`'s second argument is the
+previous value of this method, and should usually be called through to
+whenever the extended method does not handle the call itself.
+
+Similarly, the loose parser allows plugins to register themselves via
+`acorn.pluginsLoose`. The extension mechanism is the same as for the
+normal parser:
+
+```javascript
+looseParser.extend("readToken", function(nextMethod) {
+ return function() {
+ console.log("Reading a token in the loose parser!")
+ return nextMethod.call(this)
+ }
+})
+```

+// regular expression).

+var etag = require('etag')
+```
+
+### etag(entity, [options])
+
+Generate a strong ETag for the given entity. This should be the complete
+body of the entity. Strings, `Buffer`s, and `fs.Stats` are accepted. By
+default, a strong ETag is generated except for `fs.Stats`, which will
+generate a weak ETag (this can be overwritten by `options.weak`).
+
+
+
+```js
+res.setHeader('ETag', etag(body))
+```
+
+#### Options
+
+`etag` accepts these properties in the options object.
+
+##### weak
+
+Specifies if the generated ETag will include the weak validator mark (that
+is, the leading `W/`). The actual entity tag is the same. The default value
+is `false`, unless the `entity` is `fs.Stats`, in which case it is `true`.

+
+###Security Issues
+
+If you discover a security vulnerability in Express, please see [Security Policies and Procedures](Security.md).
+
+## Quick Start
+
+ The quickest way to get started with express is to utilize the executable [`express(1)`](https://github.com/expressjs/generator) to generate an application as shown below:
+
+ Install the executable. The executable's major version will match Express's:
+
+```bash
+$ npm install -g express-generator@4
+```
+
+ Create the app:
+
+```bash
+$ express /tmp/foo && cd /tmp/foo
+```
+
+ Install dependencies:
+
+```bash
+$ npm install
+```
+
+ Start the server:
+
+```bash
+$ npm start
+```
+
+## Philosophy
+
+ The Express philosophy is to provide small, robust tooling for HTTP servers, making
+ it a great solution for single page applications, web sites, hybrids, or public
+ HTTP APIs.
+
+ Express does not force you to use any specific ORM or template engine. With support for over
+ 14 template engines via [Consolidate.js](https://github.com/tj/consolidate.js),
+ you can quickly craft your perfect framework.
+
+## Examples
+
+ To view the examples, clone the Express repo and install the dependencies:
+
+```bash
+$ git clone git://github.com/expressjs/express.git --depth 1
+$ cd express
+$ npm install
+```
+
+ Then run whichever example you want:
+
+```bash
+$ node examples/content-negotiation
+```
+
+## Tests
+
+ To run the test suite, first install the dependencies, then run `npm test`:
+
+```bash
+$ npm install
+$ npm test
+```
+
