+## Contributing
+
+Thank you for your interest in go-toml! We appreciate you considering
+contributing to go-toml!
+
+The main goal is the project is to provide an easy-to-use TOML
+implementation for Go that gets the job done and gets out of your way –
+dealing with TOML is probably not the central piece of your project.
+
+As the single maintainer of go-toml, time is scarce. All help, big or
+small, is more than welcomed!
+
+### Ask questions
+
+Any question you may have, somebody else might have it too. Always feel
+free to ask them on the [issues tracker][issues-tracker].  We will try to
+answer them as clearly and quickly as possible, time permitting.
+
+Asking questions also helps us identify areas where the documentation needs
+improvement, or new features that weren't envisioned before. Sometimes, a
+seemingly innocent question leads to the fix of a bug. Don't hesitate and
+ask away!
+
+### Improve the documentation
+
+The best way to share your knowledge and experience with go-toml is to
+improve the documentation. Fix a typo, clarify an interface, add an
+example, anything goes!
+
+The documentation is present in the [README][readme] and thorough the
+source code. On release, it gets updated on [pkg.go.dev][pkg.go.dev]. To make a
+change to the documentation, create a pull request with your proposed
+changes. For simple changes like that, the easiest way to go is probably
+the "Fork this project and edit the file" button on Github, displayed at
+the top right of the file. Unless it's a trivial change (for example a
+typo), provide a little bit of context in your pull request description or
+commit message.
+
+### Report a bug
+
+Found a bug! Sorry to hear that :(. Help us and other track them down and
+fix by reporting it. [File a new bug report][bug-report] on the [issues
+tracker][issues-tracker]. The template should provide enough guidance on
+what to include. When in doubt: add more details! By reducing ambiguity and
+providing more information, it decreases back and forth and saves everyone
+time.
+
+### Code changes
+
+Want to contribute a patch? Very happy to hear that!
+
+First, some high-level rules:
+
+* A short proposal with some POC code is better than a lengthy piece of
+  text with no code. Code speaks louder than words.
+* No backward-incompatible patch will be accepted unless discussed.
+  Sometimes it's hard, and Go's lack of versioning by default does not
+  help, but we try not to break people's programs unless we absolutely have
+  to.
+* If you are writing a new feature or extending an existing one, make sure
+  to write some documentation.
+* Bug fixes need to be accompanied with regression tests.
+* New code needs to be tested.
+* Your commit messages need to explain why the change is needed, even if
+  already included in the PR description.
+
+It does sound like a lot, but those best practices are here to save time
+overall and continuously improve the quality of the project, which is
+something everyone benefits from.
+
+#### Get started
+
+The fairly standard code contribution process looks like that:
+
+1. [Fork the project][fork].
+2. Make your changes, commit on any branch you like.
+3. [Open up a pull request][pull-request]
+4. Review, potential ask for changes.
+5. Merge. You're in!
+
+Feel free to ask for help! You can create draft pull requests to gather
+some early feedback!
+
+#### Run the tests
+
+You can run tests for go-toml using Go's test tool: `go test ./...`.
+When creating a pull requests, all tests will be ran on Linux on a few Go
+versions (Travis CI), and on Windows using the latest Go version
+(AppVeyor).
+
+#### Style
+
+Try to look around and follow the same format and structure as the rest of
+the code. We enforce using `go fmt` on the whole code base.
+
+---
+
+### Maintainers-only
+
+#### Merge pull request
+
+Checklist:
+
+* Passing CI.
+* Does not introduce backward-incompatible changes (unless discussed).
+* Has relevant doc changes.
+* Has relevant unit tests.
+
+1. Merge using "squash and merge".
+2. Make sure to edit the commit message to keep all the useful information
+   nice and clean.
+3. Make sure the commit title is clear and contains the PR number (#123).
+
+#### New release
+
+1. Go to [releases][releases]. Click on "X commits to master since this
+   release".
+2. Make note of all the changes. Look for backward incompatible changes,
+   new features, and bug fixes.
+3. Pick the new version using the above and semver.
+4. Create a [new release][new-release].
+5. Follow the same format as [1.1.0][release-110].

+# go-toml
+
+Go library for the [TOML](https://toml.io/) format.
+
+This library supports TOML version
+[v1.0.0-rc.3](https://toml.io/en/v1.0.0-rc.3)
+

+
+## Development status
+
+**ℹ️ Consider go-toml v2!**
+
+The next version of go-toml is in [active development][v2-dev], and
+[nearing completion][v2-map].
+
+Though technically in beta, v2 is already more tested, [fixes bugs][v1-bugs],
+and [much faster][v2-bench]. If you only need reading and writing TOML documents
+(majority of cases), those features are implemented and the API unlikely to
+change.
+
+The remaining features will be added shortly. While pull-requests are welcome on
+v1, no active development is expected on it. When v2.0.0 is released, v1 will be
+deprecated.

+[v2-dev]: https://github.com/pelletier/go-toml/tree/v2
+[v1-bugs]: https://github.com/pelletier/go-toml/issues?q=is%3Aissue+is%3Aopen+label%3Av2-fixed
+[v2-bench]: https://github.com/pelletier/go-toml/tree/v2#benchmarks
+
+## Features
+
+Go-toml provides the following features for using data parsed from TOML documents:
+
+* Load TOML documents from files and string data
+* Easily navigate TOML structure using Tree
+* Marshaling and unmarshaling to and from data structures
+* Line & column position data for all parsed elements
+* [Query support similar to JSON-Path](query/)
+* Syntax errors contain line and column numbers
+
+## Import
+
+```go
+import "github.com/pelletier/go-toml"
+```
+
+## Usage example
+
+Read a TOML document:
+
+```go
+config, _ := toml.Load(`
+[postgres]
+user = "pelletier"
+password = "mypassword"`)
+// retrieve data directly
+user := config.Get("postgres.user").(string)
+
+// or using an intermediate object
+postgresConfig := config.Get("postgres").(*toml.Tree)
+password := postgresConfig.Get("password").(string)
+```
+
+Or use Unmarshal:
+
+```go
+type Postgres struct {
+    User     string
+    Password string
+}
+type Config struct {
+    Postgres Postgres
+}
+
+doc := []byte(`
+[Postgres]
+User = "pelletier"
+Password = "mypassword"`)
+
+config := Config{}
+toml.Unmarshal(doc, &config)
+fmt.Println("user=", config.Postgres.User)
+```
+
+Or use a query:
+
+```go
+// use a query to gather elements without walking the tree
+q, _ := query.Compile("$..[user,password]")
+results := q.Execute(config)
+for ii, item := range results.Values() {
+    fmt.Printf("Query result %d: %v\n", ii, item)
+}
+```
+
+## Documentation
+
+The documentation and additional examples are available at
+[pkg.go.dev](https://pkg.go.dev/github.com/pelletier/go-toml).
+
+## Tools
+
+Go-toml provides three handy command line tools:
+
+* `tomll`: Reads TOML files and lints them.
+
+    ```
+    go install github.com/pelletier/go-toml/cmd/tomll
+    tomll --help
+    ```
+* `tomljson`: Reads a TOML file and outputs its JSON representation.
+
+    ```
+    go install github.com/pelletier/go-toml/cmd/tomljson
+    tomljson --help
+    ```
+
+ * `jsontoml`: Reads a JSON file and outputs a TOML representation.
+
+    ```
+    go install github.com/pelletier/go-toml/cmd/jsontoml
+    jsontoml --help
+    ```
+
+### Docker image
+
+Those tools are also available as a Docker image from
+[dockerhub](https://hub.docker.com/r/pelletier/go-toml). For example, to
+use `tomljson`:
+
+```
+docker run -v $PWD:/workdir pelletier/go-toml tomljson /workdir/example.toml
+```
+
+Only master (`latest`) and tagged versions are published to dockerhub. You
+can build your own image as usual:
+
+```
+docker build -t go-toml .
+```
+
+## Contribute
+
+Feel free to report bugs and patches using GitHub's pull requests system on
+[pelletier/go-toml](https://github.com/pelletier/go-toml). Any feedback would be
+much appreciated!
+
+### Run tests
+
+`go test ./...`
+
+### Fuzzing
+
+The script `./fuzz.sh` is available to
+run [go-fuzz](https://github.com/dvyukov/go-fuzz) on go-toml.
+
+## Versioning
+
+Go-toml follows [Semantic Versioning](http://semver.org/). The supported version
+of [TOML](https://github.com/toml-lang/toml) is indicated at the beginning of
+this document. The last two major versions of Go are supported
+(see [Go Release Policy](https://golang.org/doc/devel/release.html#policy)).
