-      transformation or translation of a Source form, including but
-      not limited to compiled object code, generated documentation,
-      and conversions to other media types.
-
-      "Work" shall mean the work of authorship, whether in Source or
-      Object form, made available under the License, as indicated by a
-      copyright notice that is included in or attached to the work
-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including

-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,

-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS

+If you are new to GitHub, please start by reading [Pull Request howto](https://help.github.com/articles/about-pull-requests/)
 
 ## Legal requirements
 
 In order to protect both you and ourselves, you will need to sign the
-[Contributor License Agreement](https://identity.linuxfoundation.org/projects/cncf).
+[Contributor License
+Agreement](https://identity.linuxfoundation.org/projects/cncf). When you create
+your first PR, a link will be added as a comment that contains the steps needed
+to complete this process.
+
+## Getting Started
+
+A great way to start is by searching through our open issues. [Unassigned issues
+labeled as "help
+wanted"](https://github.com/grpc/grpc-go/issues?q=sort%3Aupdated-desc%20is%3Aissue%20is%3Aopen%20label%3A%22Status%3A%20Help%20Wanted%22%20no%3Aassignee)
+are especially nice for first-time contributors, as they should be well-defined
+problems that already have agreed-upon solutions.
+
+## Code Style
+
+We follow [Google's published Go style
+guide](https://google.github.io/styleguide/go/). Note that there are three
+primary documents that make up this style guide; please follow them as closely
+as possible. If a reviewer recommends something that contradicts those
+guidelines, there may be valid reasons to do so, but it should be rare.
 
 ## Guidelines for Pull Requests
-How to get your contributions merged smoothly and quickly.
+
+Please read the following carefully to ensure your contributions can be merged
+smoothly and quickly.
+
+### PR Contents
 
 - Create **small PRs** that are narrowly focused on **addressing a single
-  concern**. We often times receive PRs that are trying to fix several things at
-  a time, but only one fix is considered acceptable, nothing gets merged and
-  both author's & review's time is wasted. Create more PRs to address different
-  concerns and everyone will be happy.
+  concern**. We often receive PRs that attempt to fix several things at the same
+  time, and if one part of the PR has a problem, that will hold up the entire
+  PR.
 
-- The grpc package should only depend on standard Go packages and a small number
-  of exceptions. If your contribution introduces new dependencies which are NOT
-  in the [list](https://godoc.org/google.golang.org/grpc?imports), you need a
-  discussion with gRPC-Go authors and consultants.
+- If your change does not address an **open issue** with an **agreed
+  resolution**, consider opening an issue and discussing it first. If you are
+  suggesting a behavioral or API change, consider starting with a [gRFC
+  proposal](https://github.com/grpc/proposal). Many new features that are not
+  bug fixes will require cross-language agreement.
 
-- For speculative changes, consider opening an issue and discussing it first. If
-  you are suggesting a behavioral or API change, consider starting with a [gRFC
-  proposal](https://github.com/grpc/proposal).
+- If you want to fix **formatting or style**, consider whether your changes are
+  an obvious improvement or might be considered a personal preference. If a
+  style change is based on preference, it likely will not be accepted. If it
+  corrects widely agreed-upon anti-patterns, then please do create a PR and
+  explain the benefits of the change.
 
-- Provide a good **PR description** as a record of **what** change is being made
-  and **why** it was made. Link to a github issue if it exists.
-
-- Don't fix code style and formatting unless you are already changing that line
-  to address an issue. PRs with irrelevant changes won't be merged. If you do
-  want to fix formatting or style, do that in a separate PR.
-
-- Unless your PR is trivial, you should expect there will be reviewer comments
-  that you'll need to address before merging. We expect you to be reasonably
-  responsive to those comments, otherwise the PR will be closed after 2-3 weeks
-  of inactivity.
-
-- Maintain **clean commit history** and use **meaningful commit messages**. PRs
-  with messy commit history are difficult to review and won't be merged. Use
-  `rebase -i upstream/master` to curate your commit history and/or to bring in
-  latest changes from master (but avoid rebasing in the middle of a code
-  review).
-
-- Keep your PR up to date with upstream/master (if there are merge conflicts, we
-  can't really merge your change).
+- For correcting **misspellings**, please be aware that we use some terms that
+  are sometimes flagged by spell checkers. As an example, "if an only if" is
+  often written as "iff". Please do not make spelling correction changes unless
+  you are certain they are misspellings.
 
 - **All tests need to be passing** before your change can be merged. We
-  recommend you **run tests locally** before creating your PR to catch breakages
-  early on.
-  - `make all` to test everything, OR
-  - `make vet` to catch vet errors
-  - `make test` to run the tests
-  - `make testrace` to run tests in race mode
-  - optional `make testappengine` to run tests with appengine
+  recommend you run tests locally before creating your PR to catch breakages
+  early on:
 
-- Exceptions to the rules can be made if there's a compelling reason for doing so.
+  - `./scripts/vet.sh` to catch vet errors.
+  - `go test -cpu 1,4 -timeout 7m ./...` to run the tests.
+  - `go test -race -cpu 1,4 -timeout 7m ./...` to run tests in race mode.
+
+  Note that we have a multi-module repo, so `go test` commands may need to be
+  run from the root of each module in order to cause all tests to run.
+
+  *Alternatively*, you may find it easier to push your changes to your fork on
+  GitHub, which will trigger a GitHub Actions run that you can use to verify
+  everything is passing.
+
+- Note that there are two GitHub actions checks that need not be green:
+
+  1. We test the freshness of the generated proto code we maintain via the
+     `vet-proto` check. If the source proto files are updated, but our repo is
+     not updated, an optional checker will fail. This will be fixed by our team
+     in a separate PR and will not prevent the merge of your PR.
+
+  2. We run a checker that will fail if there is any change in dependencies of
+     an exported package via the `dependencies` check. If new dependencies are
+     added that are not appropriate, we may not accept your PR (see below).
+
+- If you are adding a **new file**, make sure it has the **copyright message**
+  template at the top as a comment. You can copy the message from an existing
+  file and update the year.
+
+- The grpc package should only depend on standard Go packages and a small number
+  of exceptions. **If your contribution introduces new dependencies**, you will
+  need a discussion with gRPC-Go maintainers.
+
+### PR Descriptions
+
+- **PR titles** should start with the name of the component being addressed, or
+  the type of change. Examples: transport, client, server, round_robin, xds,
+  cleanup, deps.
+
+- Read and follow the **guidelines for PR titles and descriptions** here:
+  https://google.github.io/eng-practices/review/developer/cl-descriptions.html
+
+  *particularly* the sections "First Line" and "Body is Informative".
+
+  Note: your PR description will be used as the git commit message in a
+  squash-and-merge if your PR is approved. We may make changes to this as
+  necessary.
+
+- **Does this PR relate to an open issue?** On the first line, please use the
+  tag `Fixes #<issue>` to ensure the issue is closed when the PR is merged. Or
+  use `Updates #<issue>` if the PR is related to an open issue, but does not fix
+  it. Consider filing an issue if one does not already exist.
+
+- PR descriptions *must* conclude with **release notes** as follows:
+
+  ```
+  RELEASE NOTES:
+  * <component>: <summary>
+  ```
+
+  This need not match the PR title.
+
+  The summary must:
+
+  * be something that gRPC users will understand.
+
+  * clearly explain the feature being added, the issue being fixed, or the
+    behavior being changed, etc. If fixing a bug, be clear about how the bug
+    can be triggered by an end-user.
+
+  * begin with a capital letter and use complete sentences.
+
+  * be as short as possible to describe the change being made.
+
+  If a PR is *not* end-user visible -- e.g. a cleanup, testing change, or
+  GitHub-related, use `RELEASE NOTES: n/a`.
+
+### PR Process
+
+- Please **self-review** your code changes before sending your PR. This will
+  prevent simple, obvious errors from causing delays.
+
+- Maintain a **clean commit history** and use **meaningful commit messages**.
+  PRs with messy commit histories are difficult to review and won't be merged.
+  Before sending your PR, ensure your changes are based on top of the latest
+  `upstream/master` commits, and avoid rebasing in the middle of a code review.
+  You should **never use `git push -f`** unless absolutely necessary during a
+  review, as it can interfere with GitHub's tracking of comments.
+
+- Unless your PR is trivial, you should **expect reviewer comments** that you
+  will need to address before merging. We'll label the PR as `Status: Requires
+  Reporter Clarification` if we expect you to respond to these comments in a
+  timely manner. If the PR remains inactive for 6 days, it will be marked as
+  `stale`, and we will automatically close it after 7 days if we don't hear back
+  from you. Please feel free to ping issues or bugs if you do not get a response
+  within a week.

-#### The RPC failed with error `"code = Unavailable desc = transport is closing"`
+### The RPC failed with error `"code = Unavailable desc = transport is closing"`
 
 This error means the connection the RPC is using was closed, and there are many
 possible reasons, including:
  1. mis-configured transport credentials, connection failed on handshaking
  1. bytes disrupted, possibly by a proxy in between
  1. server shutdown
+ 1. Keepalive parameters caused connection shutdown, for example if you have
+    configured your server to terminate connections regularly to [trigger DNS
+    lookups](https://github.com/grpc/grpc-go/issues/3170#issuecomment-552517779).
+    If this is the case, you may want to increase your
+    [MaxConnectionAgeGrace](https://pkg.go.dev/google.golang.org/grpc/keepalive?tab=doc#ServerParameters),
+    to allow longer RPC calls to finish.
 
 It can be tricky to debug this because the error happens on the client side but
 the root cause of the connection being closed is on the server side. Turn on
 logging on __both client and server__, and see if there are any transport
 errors.
