It was developed within [Canonical](https://www.canonical.com) as +part of the [juju](https://juju.ubuntu.com) project, and is based on a +pure Go port of the well-known [libyaml](http://pyyaml.org/wiki/LibYAML) +C library to parse and generate YAML data quickly and reliably. + +Compatibility +------------- + +The yaml package supports most of YAML 1.1 and 1.2, including support for +anchors, tags, map merging, etc. Multi-document unmarshalling is not yet +implemented, and base-60 floats from YAML 1.1 are purposefully not +supported since they're a poor design and are gone in YAML 1.2. + +Installation and usage +---------------------- + +The import path for the package is *gopkg.in/yaml.v2*. + +To install it, run: + + go get gopkg.in/yaml.v2 + +API documentation +----------------- + +If opened in a browser, the import path itself leads to the API documentation: + + * [https://gopkg.in/yaml.v2](https://gopkg.in/yaml.v2) + +API stability +------------- + +The package API for yaml v2 will remain stable as described in [gopkg.in](https://gopkg.in). + + +License +------- + +The yaml package is licensed under the Apache License 2.0.
