-# Contributing to Packer
-
-**First:** if you're unsure or afraid of _anything_, just ask or submit the
-issue or pull request anyway. You won't be yelled at for giving your best
-effort. The worst that can happen is that you'll be politely asked to change
-something. We appreciate any sort of contributions, and don't want a wall of
-rules to get in the way of that.
-
-However, for those individuals who want a bit more guidance on the best way to
-contribute to the project, read on. This document will cover what we're looking
-for. By addressing all the points we're looking for, it raises the chances we
-can quickly merge or address your contributions.
-
-## Issues
-
-### Reporting an Issue
-
-* Make sure you test against the latest released version. It is possible we
-  already fixed the bug you're experiencing.
-
-* Run the command with debug output with the environment variable `PACKER_LOG`.
-  For example: `PACKER_LOG=1 packer build template.json`. Take the _entire_
-  output and create a [gist](https://gist.github.com) for linking to in your
-  issue. Packer should strip sensitive keys from the output, but take a look
-  through just in case.
-
-* Provide a reproducible test case. If a contributor can't reproduce an issue,
-  then it dramatically lowers the chances it'll get fixed. And in some cases,
-  the issue will eventually be closed.
-
-* Respond promptly to any questions made by the Packer team to your issue. Stale
-  issues will be closed.
-
-### Issue Lifecycle
-
-1. The issue is reported.
-
-2. The issue is verified and categorized by a Packer collaborator.
-   Categorization is done via tags. For example, bugs are marked as "bugs" and
-   simple fixes are marked as "good first issue".
-
-3. Unless it is critical, the issue is left for a period of time (sometimes many
-   weeks), giving outside contributors a chance to address the issue.
-
-4. The issue is addressed in a pull request or commit. The issue will be
-   referenced in the commit message so that the code that fixes it is clearly
-   linked.
-
-5. The issue is closed.
-
-## Setting up Go
-
-If you have never worked with Go before, you will have to install its
-runtime in order to build packer.
-
-1. [Install go](https://golang.org/doc/install#install)
-
-## Setting up Packer for dev
-
-If/when you have go installed you can already `go get` packer and `make` in
-order to compile and test Packer. These instructions target
-POSIX-like environments (macOS, Linux, Cygwin, etc.) so you may need to
-adjust them for Windows or other shells.
-The instructions below are for go 1.7. or later.
-
-
-1. Download the Packer source (and its dependencies) by running
-   `go get github.com/hashicorp/packer`. This will download the Packer source to
-   `$GOPATH/src/github.com/hashicorp/packer`.
-
-2. When working on Packer, first `cd $GOPATH/src/github.com/hashicorp/packer`
-   so you can run `make` and easily access other files. Run `make help` to get
-   information about make targets.
-
-3. Make your changes to the Packer source. You can run `make` in
-   `$GOPATH/src/github.com/hashicorp/packer` to run tests and build the Packer
-   binary. Any compilation errors will be shown when the binaries are
-   rebuilding. If you don't have `make` you can simply run
-   `go build -o bin/packer .` from the project root.
-
-4. After running building Packer successfully, use
-   `$GOPATH/src/github.com/hashicorp/packer/bin/packer` to build a machine and
-   verify your changes work. For instance:
-   `$GOPATH/src/github.com/hashicorp/packer/bin/packer build template.json`.
-
-5. If everything works well and the tests pass, run `go fmt` on your code before
-   submitting a pull-request.
-
-### Opening an Pull Request
-
-Thank you for contributing! When you are ready to open a pull-request, you will
-need to [fork
-Packer](https://github.com/hashicorp/packer#fork-destination-box), push your
-changes to your fork, and then open a pull-request.
-
-For example, my github username is `cbednarski`, so I would do the following:
-
-```
-git checkout -b f-my-feature
-# Develop a patch.
-git push https://github.com/cbednarski/Packer f-my-feature
-```
-
-From there, open your fork in your browser to open a new pull-request.
-
-**Note:** Go infers package names from their file paths. This means `go build`
-will break if you `git clone` your fork instead of using `go get` on the main
-Packer project.
-
-**Note:** See '[Working with
-forks](https://help.github.com/articles/working-with-forks/)' for a better way
-to use `git push ...`.
-
-### Pull Request Lifecycle
-
-1. You are welcome to submit your pull request for commentary or review before
-  it is fully completed. Please prefix the title of your pull request with
-  "[WIP]" to indicate this. It's also a good idea to include specific questions
-  or items you'd like feedback on.
-
-2. Once you believe your pull request is ready to be merged, you can remove any
-  "[WIP]" prefix from the title and a core team member will review.
-
-3. One of Packer's core team members will look over your contribution and
-  either merge, or provide comments letting you know if there is anything left
-  to do. We do our best to provide feedback in a timely manner, but it may take
-  some time for us to respond. We may also have questions that we need answered
-  about the code, either because something doesn't make sense to us or because
-  we want to understand your thought process.
-
-4. If we have requested changes, you can either make those changes or, if you
-  disagree with the suggested changes, we can have a conversation about our
-  reasoning and agree on a path forward. This may be a multi-step process. Our
-  view is that pull requests are a chance to collaborate, and we welcome
-  conversations about how to do things better. It is the contributor's
-  responsibility to address any changes requested. While reviewers are happy to
-  give guidance, it is unsustainable for us to perform the coding work necessary
-  to get a PR into a mergeable state.
-
-5. Once all outstanding comments and checklist items have been addressed, your
-  contribution will be merged! Merged PRs will be included in the next
-  Packer release. The core team takes care of updating the
-  [CHANGELOG.md](../CHANGELOG.md) as they merge.
-
-6. In rare cases, we might decide that a PR should be closed without merging.
-  We'll make sure to provide clear reasoning when this happens.
-
-
-### Tips for Working on Packer
-
-#### Getting Your Pull Requests Merged Faster
-
-It is much easier to review pull requests that are:
-
-1. Well-documented: Try to explain in the pull request comments what your
-   change does, why you have made the change, and provide instructions for how
-   to produce the new behavior introduced in the pull request. If you can,
-   provide screen captures or terminal output to show what the changes look
-   like. This helps the reviewers understand and test the change.
-
-2. Small: Try to only make one change per pull request. If you found two bugs
-   and want to fix them both, that's _awesome_, but it's still best to submit
-   the fixes as separate pull requests. This makes it much easier for reviewers
-   to keep in their heads all of the implications of individual code changes,
-   and that means the PR takes less effort and energy to merge. In general, the
-   smaller the pull request, the sooner reviewers will be able to make time to
-   review it.
-
-3. Passing Tests: Based on how much time we have, we may not review pull
-   requests which aren't passing our tests. (Look below for advice on how to
-   run unit tests). If you need help figuring out why tests are failing, please
-   feel free to ask, but while we're happy to give guidance it is generally
-   your responsibility to make sure that tests are passing. If your pull request
-   changes an interface or invalidates an assumption that causes a bunch of
-   tests to fail, then you need to fix those tests before we can merge your PR.
-
-If we request changes, try to make those changes in a timely manner. Otherwise,
-PRs can go stale and be a lot more work for all of us to merge in the future.
-
-Even with everyone making their best effort to be responsive, it can be
-time-consuming to get a PR merged. It can be frustrating to deal with
-the back-and-forth as we make sure that we understand the changes fully. Please
-bear with us, and please know that we appreciate the time and energy you put
-into the project.
-
-#### Working on forks
-
-The easiest way to work on a fork is to set it as a remote of the Packer
-project. After following the steps in "Setting up Go to work on Packer":
-
-1. Navigate to the code:
-
-   `cd $GOPATH/src/github.com/hashicorp/packer`
-
-2. Add the remote by running:
-
-   `git remote add <name of remote> <github url of fork>`
-
-   For example:
-
-   `git remote add mwhooker https://github.com/mwhooker/packer.git`
-
-3. Checkout a feature branch:
-
-   `git checkout -b new-feature`
-
-4. Make changes.
-5. (Optional) Push your changes to the fork:
-
-   `git push -u <name of remote> new-feature`
-
-This way you can push to your fork to create a PR, but the code on disk still
-lives in the spot where the go cli tools are expecting to find it.
-
-#### Govendor
-
-If you are submitting a change that requires new or updated dependencies, please
-include them in `vendor/vendor.json` and in the `vendor/` folder. This helps
-everything get tested properly in CI.
-
-Note that you will need to use [govendor](https://github.com/kardianos/govendor)
-to do this. This step is recommended but not required; if you don't use govendor
-please indicate in your PR which dependencies have changed and to what versions.
-
-Use `govendor fetch <project>` to add dependencies to the project. See
-[govendor quick start](https://github.com/kardianos/govendor#quick-start-also-see-the-faq)
-for examples.
-
-Please only apply the minimal vendor changes to get your PR to work. Packer does
-not attempt to track the latest version for each dependency.
-
-#### Running Unit Tests
-
-You can run tests for individual packages using commands like this:
-
-```
-make test TEST=./builder/amazon/...
-```
-
-#### Running Acceptance Tests
-
-Packer has [acceptance tests](https://en.wikipedia.org/wiki/Acceptance_testing)
-for various builders. These typically require an API key (AWS, GCE), or
-additional software to be installed on your computer (VirtualBox, VMware).
-
-If you're working on a new builder or builder feature and want to verify it is
-functioning (and also hasn't broken anything else), we recommend running the
-acceptance tests.
-
-**Warning:** The acceptance tests create/destroy/modify _real resources_, which
-may incur costs for real money. In the presence of a bug, it is possible that
-resources may be left behind, which can cost money even though you were not
-using them. We recommend running tests in an account used only for that purpose
-so it is easy to see if there are any dangling resources, and so production
-resources are not accidentally destroyed or overwritten during testing.
-
-To run the acceptance tests, invoke `make testacc`:
-
-```
-make testacc TEST=./builder/amazon/ebs
-...
-```
-
-The `TEST` variable lets you narrow the scope of the acceptance tests to a
-specific package / folder. The `TESTARGS` variable is recommended to filter down
-to a specific resource to test, since testing all of them at once can sometimes
-take a very long time.
-
-To run only a specific test, use the `-run` argument:
-
-```
-make testacc TEST=./builder/amazon/ebs TESTARGS="-run TestBuilderAcc_forceDeleteSnapshot"
-```
-
-Acceptance tests typically require other environment variables to be set for
-things such as API tokens and keys. Each test should error and tell you which
-credentials are missing, so those are not documented here.
