+## Contributing to libpod
+
+This section describes how to start a contribution to libpod.
+
+### Prepare your environment
+
+Read the [install documentation to see how to install dependencies](install.md) .
+
+The install documentation will illustrate the following steps:
+- install libs and tools
+- check installed versions
+- configure network
+- how to install libpod from sources
+
+### Fork and clone libpod
+
+First you need to fork this project on GitHub.
+
+Be sure to have [defined your `$GOPATH` environment variable](https://github.com/golang/go/wiki/GOPATH).
+
+Create a path that correspond to your clone `mkdir -p $GOPATH/github.com/<you>`.
+
+Clone your fork locally:
+```shell
+$ git clone git@github.com:<you>/libpod github.com/<you> $GOPATH/github.com/<you>/libpod
+$ cd $GOPATH/github.com/<you>/libpod
+```
+
+You can also use `go get` to clone your fork:
+```shell
+$ go get github.com:<you>/libpod
+$ cd $GOPATH/github.com/<you>/libpod
+```
+
+### Deal with make
+
+Libpod use a Makefile to realize common action like building etc...
+
+You can list available actions by using:
+```shell
+$ make help
+Usage: make <target>
+...output...
+```
+
+### Install tools
+
+Makefile allow you to install needed tools:
+```shell
+$ make install.tools
+```
+
+### Building binaries and test your changes
+
+To test your changes do `make binaries` to generate your binaries.
+
+Your binaries are created inside the `bin/` directory and you can test your changes:
+```shell
+$ bin/podman -h
+bin/podman -h
+NAME:
+ podman - manage pods and images
+
+USAGE:
+ podman [global options] command [command options] [arguments...]
+
+VERSION:
+ 1.0.1-dev
+
+COMMANDS:
+ attach Attach to a running container
+ build Build an image using instructions from Dockerfiles
+ commit Create new image based on the changed container
+ container Manage Containers
+ cp Copy files/folders between a container and the local filesystem
+```
+
+Well, you can now create your own branch, apply changes on it, and then submitting your pull request.
+
+For further reading about branching [you can read this document](https://herve.beraud.io/containers/linux/podman/isolate/environment/2019/02/06/how-to-hack-on-podman.html).
+

-* Signing and pushing images to various image storages.

+* Specializing in signing and pushing images to various storage backends.
+ See [Skopeo](https://github.com/containers/skopeo/) for those tasks.
+* Container runtimes daemons for working with the Kubernetes CRI interface.
+ [CRI-O](https://github.com/kubernetes-sigs/cri-o) specializes in that.
+* Supporting `docker-compose`. We believe that Kubernetes is the defacto
+ standard for composing Pods and for orchestrating containers, making
+ Kubernetes YAML a defacto standard file format. Hence, Podman allows the
+ creation and execution of Pods from a Kubernetes YAML file (see
+ [podman-play-kube](https://github.com/containers/libpod/blob/master/docs/podman-play-kube.1.md)).
+ Podman can also generate Kubernetes YAML based on a container or Pod (see
+ [podman-generate-kube](https://github.com/containers/libpod/blob/master/docs/podman-generate-kube.1.md)),
+ which allows for an easy transition from a local development environment
+ to a production Kubernetes cluster.
