[Read more](http://techblog.netflix.com/2016/12/netflixoss-announcing-hollow.html).\n\nDocumentation is available at [http://hollow.how](http://hollow.how).  \n\n## Getting Started\n\nWe recommend jumping into the [quick start guide](http://hollow.how/quick-start) — you'll have a demo up and running in minutes, and a fully production-scalable implementation of Hollow at your fingertips in about an hour.  From there, you can plug in your data model and it's off to the races.\n\n## Get Hollow\n\nRelease binaries are available from Maven Central and jCenter.\n\n|GroupID/Org|ArtifactID/Name|Latest Stable Version|\n|-----------|---------------|---------------------|\n|com.netflix.hollow|hollow|5.1.3|\n\nIn a Maven `.pom` file:\n```xml\n        ...\n        \u003cdependency\u003e\n                \u003cgroupId\u003ecom.netflix.hollow\u003c/groupId\u003e\n                \u003cartifactId\u003ehollow\u003c/artifactId\u003e\n                \u003cversion\u003e5.1.3\u003c/version\u003e\n        \u003c/dependency\u003e\n        ...\n```\n\nIn a Gradle `build.gradle` file:\n```gradle\n        ...\n        compile 'com.netflix.hollow:hollow:5.1.3'\n        ...\n```\n        \nRelease candidate binaries, matching the `-rc\\.*` pattern for an artifact's version, are available from the jCenter [oss-candidate](https://dl.bintray.com/netflixoss/oss-candidate/) repository, which may be declared in a `build.gradle` file:\n\n```gradle\n        ...\n        repositories {\n            maven {\n                url 'https://dl.bintray.com/netflixoss/oss-candidate/'\n            }\n        }\n        ...\n```\n\n## Get Support\n\nHollow is maintained by the Platform Data Technologies team at Netflix.  Support can be obtained directly from us or from fellow users through [Gitter](https://gitter.im/Netflix/hollow) or by opening an issue in this project.\n\n## Generating the Docs\n\nTo view the docs locally you can just `make site-serve`, this will start the MkDocs server at `http://127.0.0.1:8000/`.\nYou can also run `make site-build` to build the site locally and `make site-deploy` to deploy it to Github.\n\nMkDocs runs with python, the Makefile via the `venv` task should take care of setting the Python's _virtualenv_ for the site tasks.\nIt does assume that `virtualenv` is available as a command and it also assume that we are targeting _python3_.\nInstalling Python3 is out of the scope, check your OS package manager. For example, in Mac you can use [homebrew] to install `python3` or `anaconda3`.\n\n\n[homebrew]: https://brew.sh/\n\n\n## LICENSE\n\nCopyright (c) 2016 Netflix, Inc.\n\nLicensed under the Apache License, Version 2.0 (the \"License\");\nyou may not use this file except in compliance with the License.\nYou may obtain a copy of the License at\n\n\u003chttp://www.apache.org/licenses/LICENSE-2.0\u003e\n\nUnless required by applicable law or agreed to in writing, software\ndistributed under the License is distributed on an \"AS IS\" BASIS,\nWITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\nSee the License for the specific language governing permissions and\nlimitations under the License.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnetflix%2Fhollow","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnetflix%2Fhollow","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnetflix%2Fhollow/lists"}
