+# Contributing to Lodash
+
+Contributions are always welcome. Before contributing please read the
+[code of conduct](https://github.com/lodash/lodash/blob/master/CODE_OF_CONDUCT.md)
+& [search the issue tracker](https://github.com/lodash/lodash/issues); your issue
+may have already been discussed or fixed in `master`. To contribute,
+[fork](https://help.github.com/articles/fork-a-repo/) Lodash, commit your changes,
+& [send a pull request](https://help.github.com/articles/using-pull-requests/).
+
+## Feature Requests
+
+Feature requests should be submitted in the
+[issue tracker](https://github.com/lodash/lodash/issues), with a description of
+the expected behavior & use case, where they’ll remain closed until sufficient interest,
+[e.g. :+1: reactions](https://help.github.com/articles/about-discussions-in-issues-and-pull-requests/),
+has been shown by the community. Before submitting a request, please search for
+similar ones in the
+[closed issues](https://github.com/lodash/lodash/issues?q=is%3Aissue+is%3Aclosed+label%3Aenhancement).
+
+## Pull Requests
+
+For additions or bug fixes you should only need to modify `lodash.js`. Include
+updated unit tests in the `test` directory as part of your pull request. Don’t
+worry about regenerating the `dist/` or `doc/` files.
+
+Before running the unit tests you’ll need to install, `npm i`,
+[development dependencies](https://docs.npmjs.com/files/package.json#devdependencies).
+Run unit tests from the command-line via `npm test`, or open `test/index.html` &
+`test/fp.html` in a web browser. The [Backbone](http://backbonejs.org/) &
+[Underscore](http://underscorejs.org/) test suites are included as well.
+
+## Contributor License Agreement
+
+Lodash is a member of the [jQuery Foundation](https://jquery.org/).
+As such, we request that all contributors sign the jQuery Foundation
+[contributor license agreement (CLA)](https://contribute.jquery.org/CLA/).

+
+## Coding Guidelines
+
+In addition to the following guidelines, please follow the conventions already
+established in the code.
+
+- **Spacing**:<br>
+  Use two spaces for indentation. No tabs.
+
+- **Naming**:<br>
+  Keep variable & method names concise & descriptive.<br>
+  Variable names `index`, `collection`, & `callback` are preferable to
+  `i`, `arr`, & `fn`.
+
+- **Quotes**:<br>
+  Single-quoted strings are preferred to double-quoted strings; however,
+  please use a double-quoted string if the value contains a single-quote
+  character to avoid unnecessary escaping.
+
+- **Comments**:<br>
+  Please use single-line comments to annotate significant additions, &
+  [JSDoc-style](http://www.2ality.com/2011/08/jsdoc-intro.html) comments for
+  functions.
+
+Guidelines are enforced using [JSCS](https://www.npmjs.com/package/jscs):
+```bash
+$ npm run style
+```
+
+## Tips
+
+You can opt-in to a pre-push git hook by adding an `.opt-in` file to the root of
+the project containing:
+```txt
+pre-push
+```
+
+With that, when you `git push`, the pre-push git hook will trigger and execute
+`npm run validate`.

+## lodash/fp
+
+The `lodash/fp` module is an instance of `lodash` with its methods wrapped to
+produce immutable auto-curried iteratee-first data-last methods.
+
+## Installation
+
+In a browser:
+```html
+<script src='path/to/lodash.js'></script>
+<script src='path/to/lodash.fp.js'></script>
+```
+
+In Node.js:
+```js
+// Load the fp build.
+var fp = require('lodash/fp');
+
+// Load a method category.
+var object = require('lodash/fp/object');
+
+// Load a single method for smaller builds with browserify/rollup/webpack.
+var extend = require('lodash/fp/extend');
+```
+
+## Mapping
+
+Immutable auto-curried iteratee-first data-last methods sound great, but what
+does that really mean for each method? Below is a breakdown of the mapping used
+to convert each method.
+
+#### Capped Iteratee Arguments
+
+Iteratee arguments are capped to avoid gotchas with variadic iteratees.
+```js
+// The `lodash/map` iteratee recieves three arguments: (value, index|key, collection).
+_.map(['6', '8', '10'], parseInt);
+// → [6, NaN, 2]
+
+// The `lodash/fp/map` iteratee is capped at one argument: (value).
+fp.map(parseInt)(['6', '8', '10']);
+// → [6, 8, 10]
+```
+
+Methods that cap iteratees to one argument:<br>
+<%= toFuncList(_.keys(_.pickBy(mapping.iterateeAry, _.partial(_.eq, _, 1)))) %>
+
+Methods that cap iteratees to two arguments:<br>
+<%= toFuncList(_.keys(_.pickBy(mapping.iterateeAry, _.partial(_.eq, _, 2)))) %>
+
+The iteratee of `mapKeys` is invoked with one argument: (key)
+
+#### Fixed Arity
+
+Methods have fixed arities to support auto-currying.
+```js
+// The `lodash/padStart` method accepts an optional `chars` param.
+_.padStart('a', 3, '-')
+// → '--a'
+
+// The `lodash/fp/padStart` method does not.
+fp.padStart(3)('a');
+// → '  a'
+fp.padCharsStart('-')(3)('a');
+// → '--a'
+```
+
+Methods with a fixed arity of one:<br>
+<%= toFuncList(mapping.aryMethod[1]) %>
+
+Methods with a fixed arity of two:<br>
+<%= toFuncList(mapping.aryMethod[2]) %>
+
+Methods with a fixed arity of three:<br>
+<%= toFuncList(mapping.aryMethod[3]) %>
+
+Methods with a fixed arity of four:<br>
+<%= toFuncList(mapping.aryMethod[4]) %>
+
+#### Rearranged Arguments
+
+Method arguments are rearranged to make composition easier.
+```js
+// The `lodash/filter` method accepts (collection, iteratee).
+var compact = _.partial(_.filter, _, Boolean);
+compact(['a', null, 'c']);
+// → ['a', 'c']
+
+// The `lodash/fp/filter` method accepts (iteratee, collection)
+var compact = fp.filter(Boolean);
+compact(['a', null, 'c']);
+// → ['a', 'c']
+```
+
+Methods with a fixed arity of two have an argument order of:<br>
+<%= toArgOrder(mapping.aryRearg[2]) %>
+
+Methods with a fixed arity of three have an argument order of:<br>
+<%= toArgOrder(mapping.aryRearg[3]) %>
+
+Methods with a fixed arity of four have an argument order of:<br>
+<%= toArgOrder(mapping.aryRearg[4]) %>
+
+Methods with custom argument orders:<br>
+<%= _.map(_.keys(mapping.methodRearg), function(methodName) {
+  var orders = mapping.methodRearg[methodName];
+  return ' * `_.' + methodName + '` has an order of ' + toArgOrder(orders);
+}).join('\n') %>
+
+Methods with unchanged argument orders:<br>
+<%= toFuncList(_.keys(mapping.skipRearg)) %>
+
+The methods `partial` & `partialRight` accept an array of arguments to partially
+apply as their second parameter.
+
+#### New Methods
+
+Not all variadic methods have corresponding new method variants. Feel free to
+[request](https://github.com/lodash/lodash/blob/master/.github/CONTRIBUTING.md#feature-requests)
+any additions.
+
+Methods created to accommodate Lodash’s variadic methods:<br>
+<%= toFuncList(_.keys(mapping.remap)) %>
+
+#### Aliases
+
+There are <%= _.size(mapping.aliasToReal) %> method aliases:<br>
+<%= _.map(_.keys(mapping.aliasToReal).sort(), function(alias) {
+  var realName = mapping.aliasToReal[alias];
+  return ' * `_.' + alias + '` is an alias of `_.' + realName + '`';
+}).join('\n') %>
+
+## Chaining
+
+The `lodash/fp` module **does not** convert chain sequence methods. See
+[Izaak Schroeder’s article](https://medium.com/making-internets/why-using-chain-is-a-mistake-9bc1f80d51ba)
+for more details.
+
+## Convert
+
+Although `lodash/fp` & its method modules come pre-converted, there are times
+when you may want to customize the conversion. That’s when the `convert` method
+comes in handy.
+```js
+// Every option is `true` by default.
+var _fp = fp.convert({
+  // Specify capping iteratee arguments.
+  'cap': true,
+  // Specify currying.
+  'curry': true,
+  // Specify fixed arity.
+  'fixed': true,
+  // Specify immutable operations.
+  'immutable': true,
+  // Specify rearranging arguments.
+  'rearg': true
+});
+
+// The `convert` method is available on each method too.
+var mapValuesWithKey = fp.mapValues.convert({ 'cap': false });
+
+// Here’s an example of disabling iteratee argument caps to access the `key` param.
+mapValuesWithKey(function(value, key) {
+  return key == 'a' ? -1 : value;
+})({ 'a': 1, 'b': 1 });
+// => { 'a': -1, 'b': 1 }
+```
+
+Manual conversions are also possible with the `convert` module.
+```js
+var convert = require('lodash/fp/convert');
+
+// Convert by name.
+var assign = convert('assign', require('lodash.assign'));
+
+// Convert by object.
+var fp = convert({
+  'assign': require('lodash.assign'),
+  'chunk': require('lodash.chunk')
+});
+
+// Convert by `lodash` instance.
+var fp = convert(lodash.runInContext());
+```
