Apache TinkerPop™ is a graph computing framework for both graph databases (OLTP) and graph analytic systems (OLAP). It 
provides the Gremlin graph traversal language, drivers, and tools for working with property graphs across a wide variety
of underlying data systems.

## Project overview

TinkerPop defines a common interface and language (Gremlin) so that applications can work against many different graph 
systems without being locked into a single vendor. It includes a reference in‑memory graph database (TinkerGraph), 
Gremlin Server, language variants, and a rich collection of recipes and documentation.

## Building and Testing

Building TinkerPop is supported on Linux and macOS.

TinkerPop uses [Maven](https://maven.apache.org/) and requires Java 11/17 for proper building and proper operations. To 
build, execute unit tests and package Gremlin Console/Server run:

```bash
mvn clean install
```

The zip distributions can be found in the following directories:

1. `gremlin-server/target`
2. `gremlin-console/target`

Please see the CONTRIBUTING.md file for more detailed information and options for building, test running and developing 
TinkerPop.

## Get Started

Download [Gremlin Console](https://tinkerpop.apache.org/download.html) (compatible with Java 11/17) and unzip to a 
directory, then:

```bash
$ bin/gremlin.sh

         \,,,/
         (o o)

==>graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]

```

From the Gremlin Console, you can connect to a TinkerGraph instance and run your first traversals. Refer to the 
[Getting Started](https://tinkerpop.apache.org/docs/current/tutorials/getting-started/) for detailed walkthroughs and 
examples.

## Using TinkerPop

Common ways to use TinkerPop include:

- Embedding **TinkerGraph** in your application for development, testing, or lightweight graph workloads.
- Connecting to a **Gremlin‑enabled graph database** via drivers or [Gremlin Server](https://tinkerpop.apache.org/docs/current/reference/#gremlin-server).
- Running **Gremlin traversals** from the JVM, or via Gremlin Language Variants (Python, .NET, JavaScript, Go, etc.).
- Using the **Gremlin Console** for interactive exploration, debugging, and learning.

See the [Reference Documentation](https://tinkerpop.apache.org/docs/current/reference/) for supported features,
configuration options, and other details.

## Documentation

The full TinkerPop documentation is published on the project website and is also maintained in this repository under 
`docs/src/` as AsciiDoc “books.”

When changing or adding documentation, follow the existing AsciiDoc structure in `docs/src/**` and update the 
relevant `index.asciidoc` files so new content is included in the build.

## Contributing

Contributions to Apache TinkerPop are welcome. The [Developer Documentation](https://tinkerpop.apache.org/docs/current/dev/developer)
and contributing guide describe how to set up a development environment, run tests, and submit changes.

- Contribution guidelines: `CONTRIBUTING.md` in the repository root.
- Developer documentation: https://tinkerpop.apache.org/docs/current/dev/developer/

Before opening a pull request, please:

- Discuss larger changes on the appropriate Apache mailing list.
- Ensure tests pass locally and, where appropriate, add new tests and documentation.
- Update `CHANGELOG.asciidoc` and upgrade docs when behavior or public APIs change.

## Using AI and IDE assistants

If you use AI coding agents or IDE assistants when working on TinkerPop, please consult `AGENTS.md`. That file 
summarizes:

- Recommended build and test commands.
- Code style and testing conventions.
- “Do and don’t” guidance specific to automated tools.

`AGENTS.md` is a concise guide for tools and tool‑using contributors, while `CONTRIBUTING.md` and the 
[Developer Documentation](https://tinkerpop.apache.org/docs/current/dev/developer) remain the canonical sources for 
project policies and processes.
