# Documentation

**Qdrant (read: quadrant )** is a vector similarity search engine. Use our documentation to develop a production-ready service with a convenient API to store, search, and manage vectors with an additional payload. Qdrant's expanding features allow for all sorts of neural network or semantic-based matching, faceted search, and other applications.

## First-Time Users:

There are three ways to use Qdrant:

1. [**Run a Docker image**](quick-start/) if you don't have a Python development environment. Setup a local Qdrant server and storage in a few moments. 
2. [**Get the Python client**](https://github.com/qdrant/qdrant-client) if you're familiar with Python. Just `pip install qdrant-client`. The client uses an in-memory database.
3. [**Spin up a Qdrant Cloud cluster:**](cloud/) the recommended method to run Qdrant in production. Read [Quickstart](cloud/cloud-quick-start/) to setup your first instance.

### Recommended Workflow:

![Local mode workflow](https://raw.githubusercontent.com/qdrant/qdrant-client/master/docs/images/try-develop-deploy.png)

First, try Qdrant locally using the [Qdrant Client](https://github.com/qdrant/qdrant-client) and with the help of our [Tutorials](tutorials/) and Guides. Develop a sample app from our [Examples](examples/) list and try it using a [Qdrant Docker](guides/installation/) container. Then, when you are ready for production, deploy to a Free Tier [Qdrant Cloud](cloud/) cluster.

## Common Use Cases:

Qdrant is ideal for deploying applications based on the matching of embeddings produced by neural network encoders. Check out the [Examples](examples/) section to learn more about common use cases. Also, you can visit the [Tutorials](tutorials/) page to learn how to work with Qdrant in different ways.
