+# 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 behaviour 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 behaviour 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
+behaviour and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behaviour.
+
+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 behaviours 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
+[hello@manifold.co](mailto:hello@manifold.co). 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, version 1.4,
+available at
+[http://contributor-covenant.org/version/1/4](http://contributor-covenant.org/version/1/4).

+Interactive prompt for command-line applications.

+
+## Overview
+
+![promptui](https://media.giphy.com/media/xUNda0Ngb5qsogLsBi/giphy.gif)
+
+Promptui is a library providing a simple interface to create command-line
+prompts for go. It can be easily integrated into
+[spf13/cobra](https://github.com/spf13/cobra),
+[urfave/cli](https://github.com/urfave/cli) or any cli go application.
+
+Promptui has two main input modes:
+
+- `Prompt` provides a single line for user input. Prompt supports
+ optional live validation, confirmation and masking the input.
+
+- `Select` provides a list of options to choose from. Select supports
+ pagination, search, detailed view and custom templates.
+
+For a full list of options check [GoDoc](https://godoc.org/github.com/manifoldco/promptui).
+
+## Basic Usage
+
+### Prompt
+
+```go
+package main
+
+import (
+ "errors"
+ "fmt"
+ "strconv"
+
+ "github.com/manifoldco/promptui"
+)
+
+func main() {
+ validate := func(input string) error {
+ _, err := strconv.ParseFloat(input, 64)
+ if err != nil {
+ return errors.New("Invalid number")
+ }
+ return nil
+ }
+
+ prompt := promptui.Prompt{
+ Label: "Number",
+ Validate: validate,
+ }
+
+ result, err := prompt.Run()
+
+ if err != nil {
+ fmt.Printf("Prompt failed %v\n", err)
+ return
+ }
+
+ fmt.Printf("You choose %q\n", result)
+}
+```
+
+### Select
+
+```go
+package main
+
+import (
+ "fmt"
+
+ "github.com/manifoldco/promptui"
+)
+
+func main() {
+ prompt := promptui.Select{
+ Label: "Select Day",
+ Items: []string{"Monday", "Tuesday", "Wednesday", "Thursday", "Friday",
+ "Saturday", "Sunday"},
+ }
+
+ _, result, err := prompt.Run()
+
+ if err != nil {
+ fmt.Printf("Prompt failed %v\n", err)
+ return
+ }
+
+ fmt.Printf("You choose %q\n", result)
+}
+```
+
