-# The libcontainer Contributors' Guide
-
-Want to hack on libcontainer? Awesome! Here are instructions to get you
-started. They are probably not perfect, please let us know if anything
-feels wrong or incomplete.
-
-## Reporting Issues
-
-When reporting [issues](https://github.com/docker/libcontainer/issues)
-on GitHub please include your host OS (Ubuntu 12.04, Fedora 19, etc),
-the output of `uname -a`. Please include the steps required to reproduce
-the problem if possible and applicable.
-This information will help us review and fix your issue faster.
-
-## Development Environment
-
-### Requirements
-
-For best results, use a Linux development environment.
-The following packages are required to compile libcontainer natively.
-
-- Golang 1.3
-- GCC
-- git
-- cgutils
-
-You can develop on OSX, but you are limited to Dockerfile-based builds only.
-
-### Building libcontainer from Dockerfile
-
-    make all
-
-This is the easiest way of building libcontainer.
-As this build is done using Docker, you can even run this from [OSX](https://github.com/boot2docker/boot2docker)
-
-### Testing changes with "nsinit"
-
-    make sh
-
-This will create an container that runs `nsinit exec sh` on a busybox rootfs with the configuration from ['minimal.json'](https://github.com/docker/libcontainer/blob/master/sample_configs/minimal.json).
-Like the previous command, you can run this on OSX too!
-
-### Building libcontainer directly
-
-> Note: You should add the `vendor` directory to your GOPATH to use the vendored libraries
-
-    ./update-vendor.sh
-    go get -d ./...
-    make direct-build
-    # Run the tests
-    make direct-test-short | egrep --color 'FAIL|$'
-    # Run all the test
-    make direct-test | egrep --color 'FAIL|$'
-
-### Testing Changes with "nsinit" directly
-
-To test a change:
-
-    # Install nsinit
-    make direct-install
-
-    # Optional, add a docker0 bridge
-    ip link add docker0 type bridge
-    ifconfig docker0 172.17.0.1/16 up
-
-    mkdir testfs
-    curl -sSL https://github.com/jpetazzo/docker-busybox/raw/buildroot-2014.02/rootfs.tar | tar -xC testfs
-    cd testfs
-    cp <your-sample-config.json> container.json
-    nsinit exec sh
-
-## Contribution Guidelines
-
-### Pull requests are always welcome
-
-We are always thrilled to receive pull requests, and do our best to
-process them as fast as possible. Not sure if that typo is worth a pull
-request? Do it! We will appreciate it.
-
-If your pull request is not accepted on the first try, don't be
-discouraged! If there's a problem with the implementation, hopefully you
-received feedback on what to improve.
-
-We're trying very hard to keep libcontainer lean and focused. We don't want it
-to do everything for everybody. This means that we might decide against
-incorporating a new feature. However, there might be a way to implement
-that feature *on top of* libcontainer.
-
-### Discuss your design on the mailing list
-
-We recommend discussing your plans [on the mailing
-list](https://groups.google.com/forum/?fromgroups#!forum/libcontainer)
-before starting to code - especially for more ambitious contributions.
-This gives other contributors a chance to point you in the right
-direction, give feedback on your design, and maybe point out if someone
-else is working on the same thing.
-
-### Create issues...
-
-Any significant improvement should be documented as [a GitHub
-issue](https://github.com/docker/libcontainer/issues) before anybody
-starts working on it.
-
-### ...but check for existing issues first!
-
-Please take a moment to check that an issue doesn't already exist
-documenting your bug report or improvement proposal. If it does, it
-never hurts to add a quick "+1" or "I have this problem too". This will
-help prioritize the most common problems and requests.
-
-### Conventions
-
-Fork the repo and make changes on your fork in a feature branch:
-
-- If it's a bugfix branch, name it XXX-something where XXX is the number of the
-  issue
-- If it's a feature branch, create an enhancement issue to announce your
-  intentions, and name it XXX-something where XXX is the number of the issue.
-
-Submit unit tests for your changes.  Go has a great test framework built in; use
-it! Take a look at existing tests for inspiration. Run the full test suite on
-your branch before submitting a pull request.
-
-Update the documentation when creating or modifying features. Test
-your documentation changes for clarity, concision, and correctness, as
-well as a clean documentation build. See ``docs/README.md`` for more
-information on building the docs and how docs get released.
-
-Write clean code. Universally formatted code promotes ease of writing, reading,
-and maintenance. Always run `gofmt -s -w file.go` on each changed file before
-committing your changes. Most editors have plugins that do this automatically.
-
-Pull requests descriptions should be as clear as possible and include a
-reference to all the issues that they address.
-
-Pull requests must not contain commits from other users or branches.
-
-Commit messages must start with a capitalized and short summary (max. 50
-chars) written in the imperative, followed by an optional, more detailed
-explanatory text which is separated from the summary by an empty line.
-
-Code review comments may be added to your pull request. Discuss, then make the
-suggested modifications and push additional commits to your feature branch. Be
-sure to post a comment after pushing. The new commits will show up in the pull
-request automatically, but the reviewers will not be notified unless you
-comment.
-
-Before the pull request is merged, make sure that you squash your commits into
-logical units of work using `git rebase -i` and `git push -f`. After every
-commit the test suite should be passing. Include documentation changes in the
-same commit so that a revert would remove all traces of the feature or fix.
-
-Commits that fix or close an issue should include a reference like `Closes #XXX`
-or `Fixes #XXX`, which will automatically close the issue when merged.
-
-### Testing
-
-Make sure you include suitable tests, preferably unit tests, in your pull request
-and that all the tests pass.
-
-*Instructions for running tests to be added.*
-
-### Merge approval
-
-libcontainer maintainers use LGTM (looks good to me) in comments on the code review
-to indicate acceptance.
-
-A change requires LGTMs from at lease two maintainers. One of those must come from
-a maintainer of the component affected. For example, if a change affects `netlink/`
-and `security`, it needs at least one LGTM from a maintainer of each. Maintainers
-only need one LGTM as presumably they LGTM their own change.
-
-For more details see [MAINTAINERS.md](MAINTAINERS.md)
-
-### Sign your work
-
-The sign-off is a simple line at the end of the explanation for the
-patch, which certifies that you wrote it or otherwise have the right to
-pass it on as an open-source patch.  The rules are pretty simple: if you
-can certify the below (from
-[developercertificate.org](http://developercertificate.org/)):

-    this project or the open source license(s) involved.
-```
-
-then you just add a line to every git commit message:
-
-    Docker-DCO-1.1-Signed-off-by: Joe Smith <joe.smith@email.com> (github: github_handle)
-
-using your real name (sorry, no pseudonyms or anonymous contributions.)
-
-One way to automate this, is customise your get ``commit.template`` by adding
-a ``prepare-commit-msg`` hook to your libcontainer checkout:
-
-```
-curl -o .git/hooks/prepare-commit-msg https://raw.githubusercontent.com/docker/docker/master/contrib/prepare-commit-msg.hook && chmod +x .git/hooks/prepare-commit-msg
-```
-
-* Note: the above script expects to find your GitHub user name in ``git config --get github.user``
-
-#### Small patch exception
-
-There are several exceptions to the signing requirement. Currently these are:
-
-* Your patch fixes spelling or grammar errors.
-* Your patch is a single line change to documentation contained in the
-  `docs` directory.
-* Your patch fixes Markdown formatting or syntax errors in the
-  documentation contained in the `docs` directory.
-
-If you have any questions, please refer to the FAQ in the [docs](to be written)
-
-### How can I become a maintainer?
-
-* Step 1: learn the component inside out
-* Step 2: make yourself useful by contributing code, bugfixes, support etc.
-* Step 3: volunteer on the irc channel (#libcontainer@freenode)
-
-Don't forget: being a maintainer is a time investment. Make sure you will have time to make yourself available.
-You don't have to be a maintainer to make a difference on the project!

-# The libcontainer Maintainers' Guide
-
-## Introduction
-
-Dear maintainer. Thank you for investing the time and energy to help
-make libcontainer as useful as possible. Maintaining a project is difficult,
-sometimes unrewarding work.  Sure, you will get to contribute cool
-features to the project. But most of your time will be spent reviewing,
-cleaning up, documenting, answering questions, justifying design
-decisions - while everyone has all the fun! But remember - the quality
-of the maintainers work is what distinguishes the good projects from the
-great.  So please be proud of your work, even the unglamourous parts,
-and encourage a culture of appreciation and respect for *every* aspect
-of improving the project - not just the hot new features.
-
-This document is a manual for maintainers old and new. It explains what
-is expected of maintainers, how they should work, and what tools are
-available to them.
-
-This is a living document - if you see something out of date or missing,
-speak up!
-
-## What are a maintainer's responsibility?
-
-It is every maintainer's responsibility to:
-
-* 1) Expose a clear roadmap for improving their component.
-* 2) Deliver prompt feedback and decisions on pull requests.
-* 3) Be available to anyone with questions, bug reports, criticism etc.
-  on their component. This includes IRC, GitHub requests and the mailing
-  list.
-* 4) Make sure their component respects the philosophy, design and
-  roadmap of the project.
-
-## How are decisions made?
-
-Short answer: with pull requests to the libcontainer repository.
-
-libcontainer is an open-source project with an open design philosophy. This
-means that the repository is the source of truth for EVERY aspect of the
-project, including its philosophy, design, roadmap and APIs. *If it's
-part of the project, it's in the repo. It's in the repo, it's part of
-the project.*
-
-As a result, all decisions can be expressed as changes to the
-repository. An implementation change is a change to the source code. An
-API change is a change to the API specification. A philosophy change is
-a change to the philosophy manifesto. And so on.
-
-All decisions affecting libcontainer, big and small, follow the same 3 steps:
-
-* Step 1: Open a pull request. Anyone can do this.
-
-* Step 2: Discuss the pull request. Anyone can do this.
-
-* Step 3: Accept (`LGTM`) or refuse a pull request. The relevant maintainers do 
-this (see below "Who decides what?")
-
-
-## Who decides what?
-
-All decisions are pull requests, and the relevant maintainers make
-decisions by accepting or refusing the pull request. Review and acceptance
-by anyone is denoted by adding a comment in the pull request: `LGTM`. 
-However, only currently listed `MAINTAINERS` are counted towards the required
-two LGTMs.
-
-libcontainer follows the timeless, highly efficient and totally unfair system
-known as [Benevolent dictator for life](http://en.wikipedia.org/wiki/Benevolent_Dictator_for_Life), with Michael Crosby in the role of BDFL.
-This means that all decisions are made by default by Michael. Since making
-every decision himself would be highly un-scalable, in practice decisions
-are spread across multiple maintainers.
-
-The relevant maintainers for a pull request can be worked out in two steps:
-
-* Step 1: Determine the subdirectories affected by the pull request. This
-  might be `netlink/` and `security/`, or any other part of the repo.
-
-* Step 2: Find the `MAINTAINERS` file which affects this directory. If the
-  directory itself does not have a `MAINTAINERS` file, work your way up
-  the repo hierarchy until you find one.
-
-### I'm a maintainer, and I'm going on holiday
-
-Please let your co-maintainers and other contributors know by raising a pull
-request that comments out your `MAINTAINERS` file entry using a `#`.
-
-### I'm a maintainer, should I make pull requests too?
-
-Yes. Nobody should ever push to master directly. All changes should be
-made through a pull request.
-
-### Who assigns maintainers?
-
-Michael has final `LGTM` approval for all pull requests to `MAINTAINERS` files.
-
-### How is this process changed?
-
-Just like everything else: by making a pull request :)

-# libcontainer Principles
-
-In the design and development of libcontainer we try to follow these principles:
-
-(Work in progress)
-
-* Don't try to replace every tool. Instead, be an ingredient to improve them.
-* Less code is better.
-* Fewer components are better. Do you really need to add one more class?
-* 50 lines of straightforward, readable code is better than 10 lines of magic that nobody can understand.
-* Don't do later what you can do now. "//TODO: refactor" is not acceptable in new code.
-* When hesitating between two options, choose the one that is easier to reverse.
-* "No" is temporary; "Yes" is forever. If you're not sure about a new feature, say no. You can change your mind later.
-* Containers must be portable to the greatest possible number of machines. Be suspicious of any change which makes machines less interchangeable.
-* The fewer moving parts in a container, the better.
-* Don't merge it unless you document it.
-* Don't document it unless you can keep it up-to-date.
-* Don't merge it unless you test it!
-* Everyone's problem is slightly different. Focus on the part that is the same for everyone, and solve that.

-# libcontainer: what's next?
-
-This document is a high-level overview of where we want to take libcontainer next.
-It is a curated selection of planned improvements which are either important, difficult, or both.
-
-For a more complete view of planned and requested improvements, see [the Github issues](https://github.com/docker/libcontainer/issues).
-
-To suggest changes to the roadmap, including additions, please write the change as if it were already in effect, and make a pull request.
-
-## Broader kernel support
-
-Our goal is to make libcontainer run everywhere, but currently libcontainer requires Linux version 3.8 or higher. If you’re deploying new machines for the purpose of running libcontainer, this is a fairly easy requirement to meet. However, if you’re adding libcontainer to an existing deployment, you may not have the flexibility to update and patch the kernel.
-
-## Cross-architecture support
-
-Our goal is to make libcontainer run everywhere. Recently libcontainer has
-expanded from its initial support for x86_64 systems to include POWER (ppc64
-little and big endian variants), IBM System z (s390x 64-bit), and ARM. We plan
-to continue expanding architecture support such that libcontainer containers
-can be created and used on more architectures.

-It is able to spawn new containers or join existing containers.  A root
-filesystem must be provided for use along with a container configuration file.
-
-To build `nsinit`, run `make binary`. It will save the binary into
-`bundles/nsinit`.
-
-To use `nsinit`, cd into a Linux rootfs and copy a `container.json` file into
-the directory with your specified configuration. Environment, networking,
-and different capabilities for the container are specified in this file.
-The configuration is used for each process executed inside the container.
-
-See the `sample_configs` folder for examples of what the container configuration should look like.
-
-To execute `/bin/bash` in the current directory as a container just run the following **as root**:
-```bash
-nsinit exec --tty /bin/bash
-```
-
-If you wish to spawn another process inside the container while your
-current bash session is running, run the same command again to
-get another bash shell (or change the command).  If the original
-process (PID 1) dies, all other processes spawned inside the container
-will be killed and the namespace will be removed.
-
-You can identify if a process is running in a container by
-looking to see if `state.json` is in the root of the directory.
-
-You may also specify an alternate root place where
-the `container.json` file is read and where the `state.json` file will be saved.

 #### Checkpoint & Restore
 
 libcontainer now integrates [CRIU](http://criu.org/) for checkpointing and restoring containers.
@@ -180,39 +144,9 @@ If you don't already  have `criu` installed, you can build it from source, follo
 [online instructions](http://criu.org/Installation). `criu` is also installed in the docker image
 generated when building libcontainer with docker.
 
-To try an example with `nsinit`, open two terminals to the same busybox directory.
-In the first terminal, run a command like this one:
-```bash
-nsinit exec -- sh -c 'i=0; while true; do echo $i; i=$(expr $i + 1); sleep 1; done'
-```
-
-You should see logs printing to the terminal every second. Now, in the second terminal, run:
-```bash
-nsinit checkpoint --image-path=/tmp/criu
-```
-
-The logs in your first terminal will stop and the process will exit. Finally, in the second
-terminal, run the restore command:
-```bash
-nsinit restore --image-path=/tmp/criu
-```
-
-The process will resume counting where it left off and printing to the new terminal window.
