+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at i@dario.im. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+
+## Attribution

+# Contributing to mergo
+
+First off, thanks for taking the time to contribute! ❤️
+
+All types of contributions are encouraged and valued. See the [Table of Contents](#table-of-contents) for different ways to help and details about how this project handles them. Please make sure to read the relevant section before making your contribution. It will make it a lot easier for us maintainers and smooth out the experience for all involved. The community looks forward to your contributions. 🎉
+
+> And if you like the project, but just don't have time to contribute, that's fine. There are other easy ways to support the project and show your appreciation, which we would also be very happy about:
+> - Star the project
+> - Tweet about it
+> - Refer this project in your project's readme
+> - Mention the project at local meetups and tell your friends/colleagues

+
+## Code of Conduct
+
+This project and everyone participating in it is governed by the
+[mergo Code of Conduct](https://github.com/imdario/mergoblob/master/CODE_OF_CONDUCT.md).
+By participating, you are expected to uphold this code. Please report unacceptable behavior
+to <>.
+
+
+## I Have a Question
+
+> If you want to ask a question, we assume that you have read the available [Documentation](https://pkg.go.dev/github.com/imdario/mergo).
+
+Before you ask a question, it is best to search for existing [Issues](https://github.com/imdario/mergo/issues) that might help you. In case you have found a suitable issue and still need clarification, you can write your question in this issue. It is also advisable to search the internet for answers first.
+
+If you then still feel the need to ask a question and need clarification, we recommend the following:
+
+- Open an [Issue](https://github.com/imdario/mergo/issues/new).
+- Provide as much context as you can about what you're running into.
+- Provide project and platform versions (nodejs, npm, etc), depending on what seems relevant.
+
+We will then take care of the issue as soon as possible.
+
+## I Want To Contribute
+
+> ### Legal Notice <!-- omit in toc -->
+> When contributing to this project, you must agree that you have authored 100% of the content, that you have the necessary rights to the content and that the content you contribute may be provided under the project license.
+
+### Reporting Bugs
+
+<!-- omit in toc -->
+#### Before Submitting a Bug Report
+
+A good bug report shouldn't leave others needing to chase you up for more information. Therefore, we ask you to investigate carefully, collect information and describe the issue in detail in your report. Please complete the following steps in advance to help us fix any potential bug as fast as possible.
+
+- Make sure that you are using the latest version.
+- Determine if your bug is really a bug and not an error on your side e.g. using incompatible environment components/versions (Make sure that you have read the [documentation](). If you are looking for support, you might want to check [this section](#i-have-a-question)).
+- To see if other users have experienced (and potentially already solved) the same issue you are having, check if there is not already a bug report existing for your bug or error in the [bug tracker](https://github.com/imdario/mergoissues?q=label%3Abug).
+- Also make sure to search the internet (including Stack Overflow) to see if users outside of the GitHub community have discussed the issue.
+- Collect information about the bug:
+- Stack trace (Traceback)
+- OS, Platform and Version (Windows, Linux, macOS, x86, ARM)
+- Version of the interpreter, compiler, SDK, runtime environment, package manager, depending on what seems relevant.
+- Possibly your input and the output
+- Can you reliably reproduce the issue? And can you also reproduce it with older versions?
+
+<!-- omit in toc -->
+#### How Do I Submit a Good Bug Report?
+
+> You must never report security related issues, vulnerabilities or bugs including sensitive information to the issue tracker, or elsewhere in public. Instead sensitive bugs must be sent by email to .
+<!-- You may add a PGP key to allow the messages to be sent encrypted as well. -->
+
+We use GitHub issues to track bugs and errors. If you run into an issue with the project:
+
+- Open an [Issue](https://github.com/imdario/mergo/issues/new). (Since we can't be sure at this point whether it is a bug or not, we ask you not to talk about a bug yet and not to label the issue.)
+- Explain the behavior you would expect and the actual behavior.
+- Please provide as much context as possible and describe the *reproduction steps* that someone else can follow to recreate the issue on their own. This usually includes your code. For good bug reports you should isolate the problem and create a reduced test case.
+- Provide the information you collected in the previous section.
+
+Once it's filed:
+
+- The project team will label the issue accordingly.
+- A team member will try to reproduce the issue with your provided steps. If there are no reproduction steps or no obvious way to reproduce the issue, the team will ask you for those steps and mark the issue as `needs-repro`. Bugs with the `needs-repro` tag will not be addressed until they are reproduced.
+- If the team is able to reproduce the issue, it will be marked `needs-fix`, as well as possibly other tags (such as `critical`), and the issue will be left to be implemented by someone.
+
+### Suggesting Enhancements
+
+This section guides you through submitting an enhancement suggestion for mergo, **including completely new features and minor improvements to existing functionality**. Following these guidelines will help maintainers and the community to understand your suggestion and find related suggestions.
+
+<!-- omit in toc -->
+#### Before Submitting an Enhancement
+
+- Make sure that you are using the latest version.
+- Read the [documentation]() carefully and find out if the functionality is already covered, maybe by an individual configuration.
+- Perform a [search](https://github.com/imdario/mergo/issues) to see if the enhancement has already been suggested. If it has, add a comment to the existing issue instead of opening a new one.
+- Find out whether your idea fits with the scope and aims of the project. It's up to you to make a strong case to convince the project's developers of the merits of this feature. Keep in mind that we want features that will be useful to the majority of our users and not just a small subset. If you're just targeting a minority of users, consider writing an add-on/plugin library.
+
+<!-- omit in toc -->
+#### How Do I Submit a Good Enhancement Suggestion?
+
+Enhancement suggestions are tracked as [GitHub issues](https://github.com/imdario/mergo/issues).
+
+- Use a **clear and descriptive title** for the issue to identify the suggestion.
+- Provide a **step-by-step description of the suggested enhancement** in as many details as possible.
+- **Describe the current behavior** and **explain which behavior you expected to see instead** and why. At this point you can also tell which alternatives do not work for you.
+- You may want to **include screenshots and animated GIFs** which help you demonstrate the steps or point out the part which the suggestion is related to. You can use [this tool](https://www.cockos.com/licecap/) to record GIFs on macOS and Windows, and [this tool](https://github.com/colinkeenan/silentcast) or [this tool](https://github.com/GNOME/byzanz) on Linux. <!-- this should only be included if the project has a GUI -->
+- **Explain why this enhancement would be useful** to most mergo users. You may also want to point out the other projects that solved it better and which could serve as inspiration.

+<!-- omit in toc -->

+
+A helper to merge structs and maps in Golang. Useful for configuration default values, avoiding messy if-statements.
+
+Mergo merges same-type structs and maps by setting default values in zero-value fields. Mergo won't merge unexported (private) fields. It will do recursively any exported one. It also won't merge structs inside maps (because they are not addressable using Go reflection).
+
+Also a lovely [comune](http://en.wikipedia.org/wiki/Mergo) (municipality) in the Province of Ancona in the Italian region of Marche.
+
+## Status
+
+It is ready for production use. [It is used in several projects by Docker, Google, The Linux Foundation, VMWare, Shopify, Microsoft, etc](https://github.com/imdario/mergo#mergo-in-the-wild).
+
+### Important notes
+
+#### 1.0.0
+
+In [1.0.0](//github.com/imdario/mergo/releases/tag/1.0.0) Mergo moves to a vanity URL `dario.cat/mergo`.
+
+#### 0.3.9
+
+Please keep in mind that a problematic PR broke [0.3.9](//github.com/imdario/mergo/releases/tag/0.3.9). I reverted it in [0.3.10](//github.com/imdario/mergo/releases/tag/0.3.10), and I consider it stable but not bug-free. Also, this version adds support for go modules.
+
+Keep in mind that in [0.3.2](//github.com/imdario/mergo/releases/tag/0.3.2), Mergo changed `Merge()`and `Map()` signatures to support [transformers](#transformers). I added an optional/variadic argument so that it won't break the existing code.
+
+If you were using Mergo before April 6th, 2015, please check your project works as intended after updating your local copy with ```go get -u dario.cat/mergo```. I apologize for any issue caused by its previous behavior and any future bug that Mergo could cause in existing projects after the change (release 0.2.0).

+## Install
+
+    go get dario.cat/mergo
+
+    // use in your .go code
+    import (
+        "dario.cat/mergo"
+    )
+
+## Usage
+
+You can only merge same-type structs with exported fields initialized as zero value of their type and same-types maps. Mergo won't merge unexported (private) fields but will do recursively any exported one. It won't merge empty structs value as [they are zero values](https://golang.org/ref/spec#The_zero_value) too. Also, maps will be merged recursively except for structs inside maps (because they are not addressable using Go reflection).
+
+```go
+if err := mergo.Merge(&dst, src); err != nil {
+    // ...
+}
+```
+
+Also, you can merge overwriting values using the transformer `WithOverride`.
+
+```go
+if err := mergo.Merge(&dst, src, mergo.WithOverride); err != nil {
+    // ...
+}
+```
+
+Additionally, you can map a `map[string]interface{}` to a struct (and otherwise, from struct to map), following the same restrictions as in `Merge()`. Keys are capitalized to find each corresponding exported field.
+
+```go
+if err := mergo.Map(&dst, srcMap); err != nil {
+    // ...
+}
+```
+
+Warning: if you map a struct to map, it won't do it recursively. Don't expect Mergo to map struct members of your struct as `map[string]interface{}`. They will be just assigned as values.
+
+Here is a nice example:
+
+```go
+package main
+
+import (
+	"fmt"
+	"dario.cat/mergo"
+)
+
+type Foo struct {
+	A string
+	B int64
+}
+
+func main() {
+	src := Foo{
+		A: "one",
+		B: 2,
+	}
+	dest := Foo{
+		A: "two",
+	}
+	mergo.Merge(&dest, src)
+	fmt.Println(dest)
+	// Will print
+	// {two 2}
+}
+```
+
+Note: if test are failing due missing package, please execute:
+
+    go get gopkg.in/yaml.v3
+
+### Transformers
+
+Transformers allow to merge specific types differently than in the default behavior. In other words, now you can customize how some types are merged. For example, `time.Time` is a struct; it doesn't have zero value but IsZero can return true because it has fields with zero value. How can we merge a non-zero `time.Time`?
+
+```go
+package main
+
+import (
+	"fmt"
+	"dario.cat/mergo"
+    "reflect"
+    "time"
+)
+
+type timeTransformer struct {
+}
+
+func (t timeTransformer) Transformer(typ reflect.Type) func(dst, src reflect.Value) error {
+	if typ == reflect.TypeOf(time.Time{}) {
+		return func(dst, src reflect.Value) error {
+			if dst.CanSet() {
+				isZero := dst.MethodByName("IsZero")
+				result := isZero.Call([]reflect.Value{})
+				if result[0].Bool() {
+					dst.Set(src)
+				}
+			}
+			return nil
+		}
+	}
+	return nil
+}
+
+type Snapshot struct {
+	Time time.Time
+	// ...
+}
+
+func main() {
+	src := Snapshot{time.Now()}
+	dest := Snapshot{}
+	mergo.Merge(&dest, src, mergo.WithTransformers(timeTransformer{}))
+	fmt.Println(dest)
+	// Will print
+	// { 2018-01-12 01:15:00 +0000 UTC m=+0.000000001 }
+}
+```

+## `filepath-securejoin` ##
+
+[![Build Status](https://github.com/cyphar/filepath-securejoin/actions/workflows/ci.yml/badge.svg)](https://github.com/cyphar/filepath-securejoin/actions/workflows/ci.yml)
+
+An implementation of `SecureJoin`, a [candidate for inclusion in the Go
+standard library][go#20126]. The purpose of this function is to be a "secure"
+alternative to `filepath.Join`, and in particular it provides certain
+guarantees that are not provided by `filepath.Join`.
+
+> **NOTE**: This code is *only* safe if you are not at risk of other processes
+> modifying path components after you've used `SecureJoin`. If it is possible
+> for a malicious process to modify path components of the resolved path, then
+> you will be vulnerable to some fairly trivial TOCTOU race conditions. [There
+> are some Linux kernel patches I'm working on which might allow for a better
+> solution.][lwn-obeneath]
+>
+> In addition, with a slightly modified API it might be possible to use
+> `O_PATH` and verify that the opened path is actually the resolved one -- but
+> I have not done that yet. I might add it in the future as a helper function
+> to help users verify the path (we can't just return `/proc/self/fd/<foo>`
+> because that doesn't always work transparently for all users).
+
+This is the function prototype:
+
+```go
+func SecureJoin(root, unsafePath string) (string, error)
+```
+
+This library **guarantees** the following:
+
+* If no error is set, the resulting string **must** be a child path of
+  `root` and will not contain any symlink path components (they will all be
+  expanded).
+
+* When expanding symlinks, all symlink path components **must** be resolved
+  relative to the provided root. In particular, this can be considered a
+  userspace implementation of how `chroot(2)` operates on file paths. Note that
+  these symlinks will **not** be expanded lexically (`filepath.Clean` is not
+  called on the input before processing).
+
+* Non-existent path components are unaffected by `SecureJoin` (similar to
+  `filepath.EvalSymlinks`'s semantics).
+
+* The returned path will always be `filepath.Clean`ed and thus not contain any
+  `..` components.
+
+A (trivial) implementation of this function on GNU/Linux systems could be done
+with the following (note that this requires root privileges and is far more
+opaque than the implementation in this library, and also requires that
+`readlink` is inside the `root` path):
+
+```go
+package securejoin
+
+import (
+	"os/exec"
+	"path/filepath"
+)
+
+func SecureJoin(root, unsafePath string) (string, error) {
+	unsafePath = string(filepath.Separator) + unsafePath
+	cmd := exec.Command("chroot", root,
+		"readlink", "--canonicalize-missing", "--no-newline", unsafePath)
+	output, err := cmd.CombinedOutput()
+	if err != nil {
+		return "", err
+	}
+	expanded := string(output)
+	return filepath.Join(root, expanded), nil
+}
+```

+# Extending go-git
+
+`go-git` was built in a highly extensible manner, which enables some of its functionalities to be changed or extended without the need of changing its codebase. Here are the key extensibility features:
+
+## Dot Git Storers
+
+Dot git storers are the components responsible for storing the Git internal files, including objects and references.
+
+The built-in storer implementations include [memory](storage/memory) and [filesystem](storage/filesystem). The `memory` storer stores all the data in memory, and its use look like this:
+
+```go
+	r, err := git.Init(memory.NewStorage(), nil)
+```
+
+The `filesystem` storer stores the data in the OS filesystem, and can be used as follows:
+
+```go
+    r, err := git.Init(filesystem.NewStorage(osfs.New("/tmp/foo")), nil)
+```
+
+New implementations can be created by implementing the [storage.Storer interface](storage/storer.go#L16).
+
+## Filesystem
+
+Git repository worktrees are managed using a filesystem abstraction based on [go-billy](https://github.com/go-git/go-billy). The Git operations will take place against the specific filesystem implementation. Initialising a repository in Memory can be done as follows:
+
+```go
+	fs := memfs.New()
+	r, err := git.Init(memory.NewStorage(), fs)
+```
+
+The same operation can be done against the OS filesystem:
+
+```go
+    fs := osfs.New("/tmp/foo")
+    r, err := git.Init(memory.NewStorage(), fs)
+```
+
+New filesystems (e.g. cloud based storage) could be created by implementing `go-billy`'s [Filesystem interface](https://github.com/go-git/go-billy/blob/326c59f064021b821a55371d57794fbfb86d4cb3/fs.go#L52).
+
+## Transport Schemes
+
+Git supports various transport schemes, including `http`, `https`, `ssh`, `git`, `file`. `go-git` defines the [transport.Transport interface](plumbing/transport/common.go#L48) to represent them.
+
+The built-in implementations can be replaced by calling `client.InstallProtocol`.
+
+An example of changing the built-in `https` implementation to skip TLS could look like this:
+
+```go
+	customClient := &http.Client{
+		Transport: &http.Transport{
+			TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
+		},
+	}
+
+	client.InstallProtocol("https", githttp.NewClient(customClient))
+```
+
+Some internal implementations enables code reuse amongst the different transport implementations. Some of these may be made public in the future (e.g. `plumbing/transport/internal/common`).
+
+## Cache
+
+Several different operations across `go-git` lean on caching of objects in order to achieve optimal performance. The caching functionality is defined by the [cache.Object interface](plumbing/cache/common.go#L17).
+
+Two built-in implementations are `cache.ObjectLRU` and `cache.BufferLRU`. However, the caching functionality can be customized by implementing the interface `cache.Object` interface.
+
+## Hash
+
+`go-git` uses the `crypto.Hash` interface to represent hash functions. The built-in implementations are `github.com/pjbgf/sha1cd` for SHA1 and Go's `crypto/SHA256`.
+
+The default hash functions can be changed by calling `hash.RegisterHash`.
+```go
+    func init() {
+        hash.RegisterHash(crypto.SHA1, sha1.New)
+    }
+```
+
+New `SHA1` or `SHA256` hash functions that implement the `hash.RegisterHash` interface can be registered by calling `RegisterHash`.

+# go-git Security Policy
+
+The purpose of this security policy is to outline `go-git`'s process
+for reporting, handling and disclosing security sensitive information.
+
+## Supported Versions
+
+The project follows a version support policy where only the latest minor
+release is actively supported. Therefore, only issues that impact the latest
+minor release will be fixed. Users are encouraged to upgrade to the latest
+minor/patch release to benefit from the most up-to-date features, bug fixes,
+and security enhancements.
+
+The supported versions policy applies to both the `go-git` library and its
+associated repositories within the `go-git` org.
+
+## Reporting Security Issues
+
+Please report any security vulnerabilities or potential weaknesses in `go-git`
+privately via go-git-security@googlegroups.com. Do not publicly disclose the
+details of the vulnerability until a fix has been implemented and released.
+
+During the process the project maintainers will investigate the report, so please
+provide detailed information, including steps to reproduce, affected versions, and any mitigations if known.
+
+The project maintainers will acknowledge the receipt of the report and work with
+the reporter to validate and address the issue.
+
+Please note that `go-git` does not have any bounty programs, and therefore do
+not provide financial compensation for disclosures.
+
+## Security Disclosure Process
+
+The project maintainers will make every effort to promptly address security issues.
+
+Once a security vulnerability is fixed, a security advisory will be published to notify users and provide appropriate mitigation measures.
+
+All `go-git` advisories can be found at https://github.com/go-git/go-git/security/advisories.
