+# Contributing to the AWS SDK for Go
+
+Thank you for your interest in contributing to the AWS SDK for Go!
+We work hard to provide a high-quality and useful SDK, and we greatly value
+feedback and contributions from our community. Whether it's a bug report,
+new feature, correction, or additional documentation, we welcome your issues
+and pull requests. Please read through this document before submitting any
+[issues] or [pull requests][pr] to ensure we have all the necessary information to
+effectively respond to your bug report or contribution.
+
+Jump To:
+
+* [Bug Reports](#bug-reports)
+* [Feature Requests](#feature-requests)
+* [Code Contributions](#code-contributions)
+
+
+## How to contribute
+
+*Before you send us a pull request, please be sure that:*
+
+1. You're working from the latest source on the master branch.
+2. You check existing open, and recently closed, pull requests to be sure 
+   that someone else hasn't already addressed the problem.
+3. You create an issue before working on a contribution that will take a 
+   significant amount of your time.
+
+*Creating a Pull Request*
+
+1. Fork the repository.
+2. In your fork, make your change in a branch that's based on this repo's master branch.
+3. Commit the change to your fork, using a clear and descriptive commit message.
+4. Create a pull request, answering any questions in the pull request form.
+
+For contributions that will take a significant amount of time, open a new 
+issue to pitch your idea before you get started. Explain the problem and 
+describe the content you want to see added to the documentation. Let us know 
+if you'll write it yourself or if you'd like us to help. We'll discuss your 
+proposal with you and let you know whether we're likely to accept it.   
+
+## Bug Reports
+
+You can file bug reports against the SDK on the [GitHub issues][issues] page.
+
+If you are filing a report for a bug or regression in the SDK, it's extremely
+helpful to provide as much information as possible when opening the original
+issue. This helps us reproduce and investigate the possible bug without having
+to wait for this extra information to be provided. Please read the following
+guidelines prior to filing a bug report.
+
+1. Search through existing [issues][] to ensure that your specific issue has
+   not yet been reported. If it is a common issue, it is likely there is
+   already a bug report for your problem.
+
+2. Ensure that you have tested the latest version of the SDK. Although you
+   may have an issue against an older version of the SDK, we cannot provide
+   bug fixes for old versions. It's also possible that the bug may have been
+   fixed in the latest release.
+
+3. Provide as much information about your environment, SDK version, and
+   relevant dependencies as possible. For example, let us know what version
+   of Go you are using, which and version of the operating system, and the
+   the environment your code is running in. e.g Container.
+
+4. Provide a minimal test case that reproduces your issue or any error
+   information you related to your problem. We can provide feedback much
+   more quickly if we know what operations you are calling in the SDK. If
+   you cannot provide a full test case, provide as much code as you can
+   to help us diagnose the problem. Any relevant information should be provided
+   as well, like whether this is a persistent issue, or if it only occurs
+   some of the time.
+
+## Feature Requests
+
+Open an [issue][issues] with the following:
+
+* A short, descriptive title. Ideally, other community members should be able 
+   to get a good idea of the feature just from reading the title.
+* A detailed description of the the proposed feature. 
+    * Why it should be added to the SDK.
+    *  If possible, example code to illustrate how it should work.
+* Use Markdown to make the request easier to read;
+* If you intend to implement this feature, indicate that you'd like to the issue to be assigned to you.
+
+## Code Contributions
+
+We are always happy to receive code and documentation contributions to the SDK.
+Please be aware of the following notes prior to opening a pull request:
+
+1. The SDK is released under the [Apache license][license]. Any code you submit
+   will be released under that license. For substantial contributions, we may
+   ask you to sign a [Contributor License Agreement (CLA)][cla].
+
+2. If you would like to implement support for a significant feature that is not
+   yet available in the SDK, please talk to us beforehand to avoid any
+   duplication of effort.
+
+3. Wherever possible, pull requests should contain tests as appropriate.
+   Bugfixes should contain tests that exercise the corrected behavior (i.e., the
+   test should fail without the bugfix and pass with it), and new features 
+   should be accompanied by tests exercising the feature.
+
+4. Pull requests that contain failing tests will not be merged until the test
+   failures are addressed. Pull requests that cause a significant drop in the
+   SDK's test coverage percentage are unlikely to be merged until tests have
+   been added.
+
+5. The JSON files under the SDK's `models` folder are sourced from outside the SDK.
+   Such as `models/apis/ec2/2016-11-15/api.json`. We will not accept pull requests
+   directly on these models. If you discover an issue with the models please
+   create a [GitHub issue][issues] describing the issue.
+
+### Testing
+
+To run the tests locally, running the `make unit` command will `go get` the 
+SDK's testing dependencies, and run vet, link and unit tests for the SDK.
+
+```
+make unit
+```
+
+Standard go testing functionality is supported as well. To test SDK code that
+is tagged with `codegen` you'll need to set the build tag in the go test
+command. The `make unit` command will do this automatically.
+
+```
+go test -tags codegen ./private/...
+```
+
+See the `Makefile` for additional testing tags that can be used in testing.
+
+To test on multiple platform the SDK includes several DockerFiles under the 
+`awstesting/sandbox` folder, and associated make recipes to to execute
+unit testing within environments configured for specific Go versions.
+
+```
+make sandbox-test-go18
+```
+
+To run all sandbox environments use the following make recipe
+
+```
+# Optionally update the Go tip that will be used during the batch testing
+make update-aws-golang-tip
+
+# Run all SDK tests for supported Go versions in sandboxes
+make sandbox-test
+```
+
+In addition the sandbox environment include make recipes for interactive modes
+so you can run command within the Docker container and context of the SDK.
+
+```
+make sandbox-go18
+```
+
+### Changelog Documents
+
+You can see all release changes in the `CHANGELOG.md` file at the root of the
+repository. The release notes added to this file will contain service client
+updates, and major SDK changes. When submitting a pull request please include an entry in `CHANGELOG_PENDING.md` under the appropriate changelog type so your changelog entry is included on the following release.
+
+#### Changelog Types
+
+* `SDK Features` - For major additive features, internal changes that have
+outward impact, or updates to the SDK foundations. This will result in a minor
+version change.
+* `SDK Enhancements` - For minor additive features or incremental sized changes.
+This will result in a patch version change.
+* `SDK Bugs` - For minor changes that resolve an issue. This will result in a
+patch version change.

+
+`aws-sdk-go-v2` is the v2 AWS SDK for the Go programming language.
+
+The v2 SDK requires a minimum version of `Go 1.15`.
+
+Checkout out the [release notes](https://github.com/aws/aws-sdk-go-v2/blob/main/CHANGELOG.md) for information about the latest bug
+fixes, updates, and features added to the SDK.

+
+## Maintenance and support for SDK major versions
+
+For information about maintenance and support for SDK major versions and their underlying dependencies, see the
+following in the AWS SDKs and Tools Shared Configuration and Credentials Reference Guide:
+
+* [AWS SDKs and Tools Maintenance Policy](https://docs.aws.amazon.com/credref/latest/refdocs/maint-policy.html)
+* [AWS SDKs and Tools Version Support Matrix](https://docs.aws.amazon.com/credref/latest/refdocs/version-support-matrix.html)
+
+## Getting started
+To get started working with the SDK setup your project for Go modules, and retrieve the SDK dependencies with `go get`.
+This example shows how you can use the v2 SDK to make an API request using the SDK's [Amazon DynamoDB] client.
+
+###### Initialize Project
+```sh
+$ mkdir ~/helloaws
+$ cd ~/helloaws
+$ go mod init helloaws
+```
+###### Add SDK Dependencies
+```sh
+$ go get github.com/aws/aws-sdk-go-v2/aws
+$ go get github.com/aws/aws-sdk-go-v2/config
+$ go get github.com/aws/aws-sdk-go-v2/service/dynamodb
+```
+
+###### Write Code
+In your preferred editor add the following content to `main.go`
+
+```go
+package main
+
+import (
+    "context"
+    "fmt"
+    "log"
+
+    "github.com/aws/aws-sdk-go-v2/aws"
+    "github.com/aws/aws-sdk-go-v2/config"
+    "github.com/aws/aws-sdk-go-v2/service/dynamodb"
+)
+
+func main() {
+    // Using the SDK's default configuration, loading additional config
+    // and credentials values from the environment variables, shared
+    // credentials, and shared configuration files
+    cfg, err := config.LoadDefaultConfig(context.TODO(), config.WithRegion("us-west-2"))
+    if err != nil {
+        log.Fatalf("unable to load SDK config, %v", err)
+    }
+
+    // Using the Config value, create the DynamoDB client
+    svc := dynamodb.NewFromConfig(cfg)
+
+    // Build the request with its input parameters
+    resp, err := svc.ListTables(context.TODO(), &dynamodb.ListTablesInput{
+        Limit: aws.Int32(5),
+    })
+    if err != nil {
+        log.Fatalf("failed to list tables, %v", err)
+    }
+
+    fmt.Println("Tables:")
+    for _, tableName := range resp.TableNames {
+        fmt.Println(tableName)
+    }
+}
+```
+
+###### Compile and Execute
+```sh
+$ go run .
+Table:
+tableOne
+tableTwo
+```
+
+## Getting Help
+
+Please use these community resources for getting help. We use the GitHub issues
+for tracking bugs and feature requests.

+* If you think you may have found a bug, please open an [issue](https://github.com/aws/aws-sdk-go-v2/issues/new/choose).
+
+This SDK implements AWS service APIs. For general issues regarding the AWS services and their limitations, you may also take a look at the [Amazon Web Services Discussion Forums](https://forums.aws.amazon.com/).
+
+### Opening Issues
+
+If you encounter a bug with the AWS SDK for Go we would like to hear about it.
+Search the [existing issues][Issues] and see
+if others are also experiencing the issue before opening a new issue. Please
+include the version of AWS SDK for Go, Go language, and OS you’re using. Please
+also include reproduction case when appropriate.
+
+The GitHub issues are intended for bug reports and feature requests. For help
+and questions with using AWS SDK for Go please make use of the resources listed
+in the [Getting Help](#getting-help) section.
+Keeping the list of open issues lean will help us respond in a timely manner.
+
+## Feedback and contributing
+
+The v2 SDK will use GitHub [Issues] to track feature requests and issues with the SDK. In addition, we'll use GitHub [Projects] to track large tasks spanning multiple pull requests, such as refactoring the SDK's internal request lifecycle. You can provide feedback to us in several ways. 
+
+**GitHub issues**. To provide feedback or report bugs, file GitHub [Issues] on the SDK. This is the preferred mechanism to give feedback so that other users can engage in the conversation, +1 issues, etc. Issues you open will be evaluated, and included in our roadmap for the GA launch.
+
+**Contributing**. You can open pull requests for fixes or additions to the AWS SDK for Go 2.0. All pull requests must be submitted under the Apache 2.0 license and will be reviewed by an SDK team member before being merged in. Accompanying unit tests, where possible, are appreciated.

+
+      You may add Your own copyright statement to Your modifications and

+      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.

+      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

+      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.

+// Package retry provides interfaces and implementations for SDK request retry behavior.
+//
+// # Retryer Interface and Implementations
+//
+// This package defines Retryer interface that is used to either implement custom retry behavior
+// or to extend the existing retry implementations provided by the SDK. This package provides a single
+// retry implementation: Standard.
+//
+// # Standard
+//
+// Standard is the default retryer implementation used by service clients. The standard retryer is a rate limited
+// retryer that has a configurable max attempts to limit the number of retry attempts when a retryable error occurs.
+// In addition, the retryer uses a configurable token bucket to rate limit the retry attempts across the client,
+// and uses an additional delay policy to limit the time between a requests subsequent attempts.
+//
+// By default the standard retryer uses the DefaultRetryables slice of IsErrorRetryable types to determine whether
+// a given error is retryable. By default this list of retryables includes the following:
+//   - Retrying errors that implement the RetryableError method, and return true.
+//   - Connection Errors
+//   - Errors that implement a ConnectionError, Temporary, or Timeout method that return true.
+//   - Connection Reset Errors.
+//   - net.OpErr types that are dialing errors or are temporary.
+//   - HTTP Status Codes: 500, 502, 503, and 504.
+//   - API Error Codes
+//   - RequestTimeout, RequestTimeoutException
+//   - Throttling, ThrottlingException, ThrottledException, RequestThrottledException, TooManyRequestsException,
+//     RequestThrottled, SlowDown, EC2ThrottledException
+//   - ProvisionedThroughputExceededException, RequestLimitExceeded, BandwidthLimitExceeded, LimitExceededException
+//   - TransactionInProgressException, PriorRequestNotComplete
+//
+// The standard retryer will not retry a request in the event if the context associated with the request
+// has been cancelled. Applications must handle this case explicitly if they wish to retry with a different context
+// value.
+//
+// You can configure the standard retryer implementation to fit your applications by constructing a standard retryer
+// using the NewStandard function, and providing one more functional argument that mutate the StandardOptions
+// structure. StandardOptions provides the ability to modify the token bucket rate limiter, retryable error conditions,
+// and the retry delay policy.
+//
+// For example to modify the default retry attempts for the standard retryer:
+//
+//	// configure the custom retryer
+//	customRetry := retry.NewStandard(func(o *retry.StandardOptions) {
+//	    o.MaxAttempts = 5
+//	})
+//
+//	// create a service client with the retryer
+//	s3.NewFromConfig(cfg, func(o *s3.Options) {
+//	    o.Retryer = customRetry
+//	})
+//
+// # Utilities
+//
+// A number of package functions have been provided to easily wrap retryer implementations in an implementation agnostic
+// way. These are:
+//
+//	AddWithErrorCodes      - Provides the ability to add additional API error codes that should be considered retryable
+//	                        in addition to those considered retryable by the provided retryer.
+//
+//	AddWithMaxAttempts     - Provides the ability to set the max number of attempts for retrying a request by wrapping
+//	                         a retryer implementation.
+//
+//	AddWithMaxBackoffDelay - Provides the ability to set the max back off delay that can occur before retrying a
+//	                         request by wrapping a retryer implementation.
+//
+// The following package functions have been provided to easily satisfy different retry interfaces to further customize
+// a given retryer's behavior:
+//
+//	BackoffDelayerFunc   - Can be used to wrap a function to satisfy the BackoffDelayer interface. For example,
+//	                       you can use this method to easily create custom back off policies to be used with the
+//	                       standard retryer.
+//
+//	IsErrorRetryableFunc - Can be used to wrap a function to satisfy the IsErrorRetryable interface. For example,
+//	                       this can be used to extend the standard retryer to add additional logic to determine if an
+//	                       error should be retried.
+//
+//	IsErrorTimeoutFunc   - Can be used to wrap a function to satisfy IsErrorTimeout interface. For example,
+//	                       this can be used to extend the standard retryer to add additional logic to determine if an
+//	                        error should be considered a timeout.

+// Package v4 implements signing for AWS V4 signer
+//
+// Provides request signing for request that need to be signed with
+// AWS V4 Signatures.
+//
+// # Standalone Signer
+//
+// Generally using the signer outside of the SDK should not require any additional
+//
+//	The signer does this by taking advantage of the URL.EscapedPath method. If your request URI requires
+//
+// additional escaping you many need to use the URL.Opaque to define what the raw URI should be sent
+// to the service as.
+//
+// The signer will first check the URL.Opaque field, and use its value if set.
+// The signer does require the URL.Opaque field to be set in the form of:
+//
+//	"//<hostname>/<path>"
+//
+//	// e.g.
+//	"//example.com/some/path"
+//
+// The leading "//" and hostname are required or the URL.Opaque escaping will
+// not work correctly.
+//
+// If URL.Opaque is not set the signer will fallback to the URL.EscapedPath()
+// method and using the returned value.
+//
+// AWS v4 signature validation requires that the canonical string's URI path
+// element must be the URI escaped form of the HTTP request's path.
+// http://docs.aws.amazon.com/general/latest/gr/sigv4-create-canonical-request.html
+//
+// The Go HTTP client will perform escaping automatically on the request. Some
+// of these escaping may cause signature validation errors because the HTTP
+// request differs from the URI path or query that the signature was generated.
+// https://golang.org/pkg/net/url/#URL.EscapedPath
+//
+// Because of this, it is recommended that when using the signer outside of the
+// SDK that explicitly escaping the request prior to being signed is preferable,
+// and will help prevent signature validation errors. This can be done by setting
+// the URL.Opaque or URL.RawPath. The SDK will use URL.Opaque first and then
+// call URL.EscapedPath() if Opaque is not set.
+//
+// Test `TestStandaloneSign` provides a complete example of using the signer
+// outside of the SDK and pre-escaping the URI path.
