+# 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 one of the project maintainers https://github.com/orgs/space-code/people. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and 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
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at [http://contributor-covenant.org/version/1/4][version]

+# Contributing Guidelines
+
+This document contains information and guidelines about contributing to this project.
+Please read it before you start participating.
+
+**Topics**
+
+* [Reporting Issues](#reporting-issues)
+* [Submitting Pull Requests](#submitting-pull-requests)
+* [Developers Certificate of Origin](#developers-certificate-of-origin)
+* [Code of Conduct](#code-of-conduct)
+
+## Reporting Issues
+
+A great way to contribute to the project is to send a detailed issue when you encounter a problem. We always appreciate a well-written, thorough bug report.
+
+Check that the project issues database doesn't already include that problem or suggestion before submitting an issue. If you find a match, feel free to vote for the issue by adding a reaction. Doing this helps prioritize the most common problems and requests.
+
+When reporting issues, please fill out our issue template. The information the template asks for will help us review and fix your issue faster.
+
+## Submitting Pull Requests
+
+You can contribute by fixing bugs or adding new features. For larger code changes, we recommend first discussing your ideas on our [GitHub Discussions](https://github.com/space-code/builder-macro/discussions). When submitting a pull request, please add relevant tests and ensure your changes don't break any existing tests.
+
+## Developer's Certificate of Origin 1.1
+
+By making a contribution to this project, I certify that:
+
+- (a) The contribution was created in whole or in part by me and I
+      have the right to submit it under the open source license
+      indicated in the file; or
+
+- (b) The contribution is based upon previous work that, to the best
+      of my knowledge, is covered under an appropriate open source
+      license and I have the right under that license to submit that
+      work with modifications, whether created in whole or in part
+      by me, under the same open source license (unless I am
+      permitted to submit under a different license), as indicated
+      in the file; or
+
+- (c) The contribution was provided directly to me by some other
+      person who certified (a), (b) or (c) and I have not modified
+      it.
+
+- (d) I understand and agree that this project and the contribution
+      are public and that a record of the contribution (including all
+      personal information I submit with it, including my sign-off) is
+      maintained indefinitely and may be redistributed consistent with
+      this project or the open source license(s) involved.
+
+## Code of Conduct
+
+The Code of Conduct governs how we behave in public or in private
+whenever the project will be judged by our actions.
+We expect it to be honored by everyone who contributes to this project.
+
+See [CODE_OF_CONDUCT.md](https://github.com/space-code/builder-macro/blob/master/CODE_OF_CONDUCT.md) for details.
+
+---
+
+*Some of the ideas and wording for the statements above were based on work by the [Docker](https://github.com/docker/docker/blob/master/CONTRIBUTING.md) and [Linux](https://elinux.org/Developer_Certificate_Of_Origin) communities. We commend them for their efforts to facilitate collaboration in their projects.*

+## Usage
+```swift
+import BuilderMacro
+
+@Builder
+struct Person {
+    let id: UUID
+    let name: String
+    let bday: Date
+}
+
+// Expanded
+
+struct Person {
+    let firstName: String, let lastName: String, let middleName: String
+    let birthday: Date
+    let city: String
+
+    struct PersonBuilder {
+        var firstName: String?
+        var lastName: String?
+        var middleName: String?
+        var birthday: Date?
+        var city: String?
+
+        func firstName(_ firstName: String) -> Self {
+            var copy = self
+            copy.firstName = firstName
+            return copy
+        }
+
+        func lastName(_ lastName: String) -> Self {
+            var copy = self
+            copy.lastName = lastName
+            return copy
+        }
+
+        func middleName(_ middleName: String) -> Self {
+            var copy = self
+            copy.middleName = middleName
+            return copy
+        }
+
+        func birthday(_ birthday: Date) -> Self {
+            var copy = self
+            copy.birthday = birthday
+            return copy
+        }
+
+        func city(_ city: String) -> Self {
+            var copy = self
+            copy.city = city
+            return copy
+        }
+
+        enum BuildError: Swift.Error {
+            case missingRequiredField(description: String)
+        }
+
+        func build() throws -> Person {
+            guard let firstName = firstName else {
+                throw BuildError.missingRequiredField(description: "firstName")
+            }
+
+            guard let lastName = lastName else {
+                throw BuildError.missingRequiredField(description: "lastName")
+            }
+
+            guard let middleName = middleName else {
+                throw BuildError.missingRequiredField(description: "middleName")
+            }
+
+            guard let birthday = birthday else {
+                throw BuildError.missingRequiredField(description: "birthday")
+            }
+
+            guard let city = city else {
+                throw BuildError.missingRequiredField(description: "city")
+            }
+
+            return Person(
+                firstName: firstName,
+                lastName: lastName,
+                middleName: middleName,
+                birthday: birthday,
+                city: city
+            )
+        }
+    }
+}
+```
+
+If a property type is optional, you can force validation of nil values by passing the addGuards parameter to the builder macro like this::
+
+```swift
+import BuilderMacro
+
+@Builder(addGuards: true)
+struct Person {
+    let id: UUID
+    let name: String
+    let bday: Date
+}
+```
+
+## Requirements
+- iOS 13.0+ / macOS 10.15+ / tvOS 13.0+ / watchOS 6.0+
+- Xcode 15.0
+- Swift 5.9
+
+## Installation
+### Swift Package Manager
+
+The [Swift Package Manager](https://swift.org/package-manager/) is a tool for automating the distribution of Swift code and is integrated into the `swift` compiler. It is in early development, but `builder-macro` does support its use on supported platforms.
+
+Once you have your Swift package set up, adding `builder-macro` as a dependency is as easy as adding it to the `dependencies` value of your `Package.swift`.
+
+```swift
+dependencies: [
+    .package(url: "https://github.com/space-code/builder-macro.git", .upToNextMajor(from: "1.0.0"))
+]
+```
