Druid is designed for workflows where fast queries and ingest really matter. Druid excels at powering UIs, running operational (ad-hoc) queries, or handling high concurrency. Consider Druid as an open source alternative to data warehouses for a variety of use cases. The [design documentation](https://druid.apache.org/docs/latest/design/architecture.html) explains the key concepts.
You can get started with Druid with our [local](https://druid.apache.org/docs/latest/tutorials/quickstart.html) or [Docker](http://druid.apache.org/docs/latest/tutorials/docker.html) quickstart.
Druid provides a rich set of APIs (via HTTP and [JDBC](https://druid.apache.org/docs/latest/querying/sql.html#jdbc)) for loading, managing, and querying your data.
Load [streaming](https://druid.apache.org/docs/latest/ingestion/index.html#streaming) and [batch](https://druid.apache.org/docs/latest/ingestion/index.html#batch) data using a point-and-click wizard to guide you through ingestion setup. Monitor one off tasks and ingestion supervisors.
Manage your cluster with ease. Get a view of your [datasources](https://druid.apache.org/docs/latest/design/architecture.html), [segments](https://druid.apache.org/docs/latest/design/segments.html), [ingestion tasks](https://druid.apache.org/docs/latest/ingestion/tasks.html), and [services](https://druid.apache.org/docs/latest/design/processes.html) from one convenient location. All powered by [SQL systems tables](https://druid.apache.org/docs/latest/querying/sql.html#metadata-tables), allowing you to see the underlying query for each view.
Use the built-in query workbench to prototype [DruidSQL](https://druid.apache.org/docs/latest/querying/sql.html) and [native](https://druid.apache.org/docs/latest/querying/querying.html) queries or connect one of the [many tools](https://druid.apache.org/libraries.html) that help you make the most out of Druid.
See the [latest documentation](https://druid.apache.org/docs/latest/) for the documentation for the current official release. If you need information on a previous release, you can browse [previous releases documentation](https://druid.apache.org/docs/).
Make documentation and tutorials updates in [`/docs`](https://github.com/apache/druid/tree/master/docs) using [Markdown](https://www.markdownguide.org/) or extended Markdown [(MDX)](https://mdxjs.com/). Then, open a pull request.
To build the site locally, you need Node 16.14 or higher and to install Docusaurus 2 with `npm|yarn install` in the `website` directory. Then you can run `npm|yarn start` to launch a local build of the docs.
If you're looking to update non-doc pages like Use Cases, those files are in the [`druid-website-src`](https://github.com/apache/druid-website-src/tree/master) repo.
