+# How to contribute #
+
+We'd love to accept your patches and contributions to this project. There are
+a just a few small guidelines you need to follow.
+
+
+## Contributor License Agreement ##
+
+Contributions to any Google project must be accompanied by a Contributor
+License Agreement. This is not a copyright **assignment**, it simply gives
+Google permission to use and redistribute your contributions as part of the
+project.
+
+ * If you are an individual writing original source code and you're sure you
+ own the intellectual property, then you'll need to sign an [individual
+ CLA][].
+
+ * If you work for a company that wants to allow you to contribute your work,
+ then you'll need to sign a [corporate CLA][].
+
+You generally only need to submit a CLA once, so if you've already submitted
+one (even if it was for a different project), you probably don't need to do it
+again.
+
+[individual CLA]: https://developers.google.com/open-source/cla/individual
+[corporate CLA]: https://developers.google.com/open-source/cla/corporate
+
+
+## Submitting a patch ##
+
+ 1. It's generally best to start by opening a new issue describing the bug or
+ feature you're intending to fix. Even if you think it's relatively minor,
+ it's helpful to know what people are working on. Mention in the initial
+ issue that you are planning to work on that bug or feature so that it can
+ be assigned to you.
+
+ 1. Follow the normal process of [forking][] the project, and setup a new
+ branch to work in. It's important that each group of changes be done in
+ separate branches in order to ensure that a pull request only includes the
+ commits related to that bug or feature.
+
+ 1. Go makes it very simple to ensure properly formatted code, so always run
+ `go fmt` on your code before committing it. You should also run
+ [golint][] over your code. As noted in the [golint readme][], it's not
+ strictly necessary that your code be completely "lint-free", but this will
+ help you find common style issues.
+
+ 1. Any significant changes should almost always be accompanied by tests. The
+ project already has good test coverage, so look at some of the existing
+ tests if you're unsure how to go about it. [gocov][] and [gocov-html][]
+ are invaluable tools for seeing which parts of your code aren't being
+ exercised by your tests.
+
+ 1. Do your best to have [well-formed commit messages][] for each change.
+ This provides consistency throughout the project, and ensures that commit
+ messages are able to be formatted properly by various git tools.
+
+ 1. Finally, push the commits to your fork and submit a [pull request][].

+gofuzz
+======
+
+gofuzz is a library for populating go objects with random values.
+
+[](https://godoc.org/github.com/google/gofuzz)
+[](https://travis-ci.org/google/gofuzz)
+
+This is useful for testing:
+
+* Do your project's objects really serialize/unserialize correctly in all cases?
+* Is there an incorrectly formatted object that will cause your project to panic?
+
+Import with ```import "github.com/google/gofuzz"```
+
+You can use it on single variables:
+```go
+f := fuzz.New()
+var myInt int
+f.Fuzz(&myInt) // myInt gets a random value.
+```
+
+You can use it on maps:
+```go
+f := fuzz.New().NilChance(0).NumElements(1, 1)
+var myMap map[ComplexKeyType]string
+f.Fuzz(&myMap) // myMap will have exactly one element.
+```
+
+Customize the chance of getting a nil pointer:
+```go
+f := fuzz.New().NilChance(.5)
+var fancyStruct struct {
+ A, B, C, D *string
+}
+f.Fuzz(&fancyStruct) // About half the pointers should be set.
+```
+
+You can even customize the randomization completely if needed:
+```go
+type MyEnum string
+const (
+ A MyEnum = "A"
+ B MyEnum = "B"
+)
+type MyInfo struct {
+ Type MyEnum
+ AInfo *string
+ BInfo *string
+}
+
+f := fuzz.New().NilChance(0).Funcs(
+ func(e *MyInfo, c fuzz.Continue) {
+ switch c.Intn(2) {
+ case 0:
+ e.Type = A
+ c.Fuzz(&e.AInfo)
+ case 1:
+ e.Type = B
+ c.Fuzz(&e.BInfo)
+ }
+ },
+)
+
+var myObject MyInfo
+f.Fuzz(&myObject) // Type will correspond to whether A or B info is set.
+```
+
+See more examples in ```example_test.go```.
+
+Happy testing!
