+You can opt-in to a pre-push git hook by adding an `.opt-in` file to the root of

+```txt
+pre-push
+```
+
+With that, when you `git push`, the pre-push git hook will trigger and execute
+`npm run validate`.

+## 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 receives 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
+// `lodash/padStart` accepts an optional `chars` param.
+_.padStart('a', 3, '-')
+// → '--a'
+
+// `lodash/fp/padStart` does not.
+fp.padStart(3)('a');
+// → '  a'
+fp.padCharsStart('-')(3)('a');
+// → '--a'
+```
+
+Methods with a fixed arity of one:<br>
+<%= toFuncList(_.difference(mapping.aryMethod[1], _.keys(mapping.skipFixed))) %>
+
+Methods with a fixed arity of two:<br>
+<%= toFuncList(_.difference(mapping.aryMethod[2], _.keys(mapping.skipFixed))) %>
+
+Methods with a fixed arity of three:<br>
+<%= toFuncList(_.difference(mapping.aryMethod[3], _.keys(mapping.skipFixed))) %>
+
+Methods with a fixed arity of four:<br>
+<%= toFuncList(_.difference(mapping.aryMethod[4], _.keys(mapping.skipFixed))) %>
+
+#### Rearranged Arguments
+
+Method arguments are rearranged to make composition easier.
+```js
+// `lodash/filter` is data-first iteratee-last:
+// (collection, iteratee)
+var compact = _.partial(_.filter, _, Boolean);
+compact(['a', null, 'c']);
+// → ['a', 'c']
+
+// `lodash/fp/filter` is iteratee-first data-last:
+// (iteratee, collection)
+var compact = fp.filter(Boolean);
+compact(['a', null, 'c']);
+// → ['a', 'c']
+```
+
+##### Most methods follow these rules
+
+A fixed arity of two has an argument order of:<br>
+<%= toArgOrder(mapping.aryRearg[2]) %>
+
+A fixed arity of three has an argument order of:<br>
+<%= toArgOrder(mapping.aryRearg[3]) %>
+
+A fixed arity of four has an argument order of:<br>
+<%= toArgOrder(mapping.aryRearg[4]) %>
+
+##### Exceptions to the rules
+
+Methods that accept an array of arguments as their second parameter:<br>
+<%= toFuncList(_.keys(mapping.methodSpread)) %>
+
+Methods with unchanged argument orders:<br>
+<%= toFuncList(_.keys(mapping.skipRearg)) %>
+
+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') %>
+
+#### 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) {

+## Placeholders
+
+The placeholder argument, which defaults to `_`, may be used to fill in method
+arguments in a different order. Placeholders are filled by the first available
+arguments of the curried returned function.
+```js
+// The equivalent of `2 > 5`.
+_.gt(2)(5);
+// → false
+
+// The equivalent of `_.gt(5, 2)` or `5 > 2`.
+_.gt(_, 2)(5);
+// → true
+```
+
+## 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)
+on using functional composition as an alternative to method chaining.
+
 ## Convert
 
-Although `lodash/fp` & its method modules come pre-converted there are times when
-you may want to convert another lodash package or create a customized conversion.
-That’s when the `convert` module comes in handy.
+Although `lodash/fp` & its method modules come pre-converted, there are times

+comes in handy.

+// Every option is `true` by default.
+var _fp = fp.convert({

+  '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');

-## Mapping
-
-Immutable auto-curried iteratee-first data-last methods sound great, but what’s
-that really mean for each method? Below is a breakdown of the mapping used to
-convert each method.
-
-#### Capped Iteratee Arguments
-
-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 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
-
-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(mapping.methodRearg, function(orders, 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
-
-Methods created to accommodate Lodash’s variadic methods:<br>
-<%= toFuncList(_.keys(mapping.remap)) %>
-
-#### Aliases
-
-There are <%= _.size(mapping.aliasToReal) %> method aliases:<br>
-<%= _.map(mapping.aliasToReal, function(realName, alias) {
-  return ' * Added `_.' + alias + '` as an alias of `_.' + realName + '`';
-}).join('\n') %>
