# Quick start workflow
# Getting started with NebulaGraph

The quick start introduces the simplest workflow to use NebulaGraph, including deploying NebulaGraph, connecting to NebulaGraph, and doing basic CRUD.
This topic describes how to use NebulaGraph with Docker Desktop and on-premises deployment workflow to quickly get started with NebulaGraph.

## Steps
## Using NebulaGraph with Docker Desktop

Users can quickly deploy and use NebulaGraph in the following steps.
NebulaGraph is available as a [Docker Extension](https://hub.docker.com/extensions/weygu/nebulagraph-dd-ext) that you can easily install and run on your Docker Desktop. You can quickly deploy NebulaGraph using Docker Desktop with just one click.

1. Install Docker Desktop

- [Install Docker Desktop on Mac](https://docs.docker.com/docker-for-mac/install/)
- [Install Docker Desktop on Windows](https://docs.docker.com/docker-for-windows/install/)

!!! caution
To install Docker Desktop, you need to install [WSL 2](https://docs.docker.com/desktop/install/windows-install/#system-requirements) first.

2. In the left sidebar of Docker Desktop, click **Extensions** or **Add Extensions**.
3. On the Extensions Marketplace, search for NebulaGraph and click **Install**.

![docker](https://docs-cdn.nebula-graph.com.cn/figures/docker.png)

Click **Update** to update NebulaGraph to the latest version when a new version is available.

![docker-update](https://docs-cdn.nebula-graph.com.cn/figures/docker-update.png)

4. Click **Open** to navigate to the NebulaGraph extension page.

5. At the top of the page, click **Studio in Browser** to use NebulaGraph.

For more information about how to use NebulaGraph with Docker Desktop, see the following video:

## Deploying NebulaGraph on-premises workflow

The following workflow describes how to use NebulaGraph on-premises, including deploying NebulaGraph, connecting to NebulaGraph, and running basic CRUD.

- Monitoring and statistics

## Change
- Fix the crash caused by encoding parameter expressions to the storage layer for execution.

- If you want to upgrade NebulaGraph from version 3.1 to 3.4, please follow the instructions in the [upgrade document](../../4.deployment-and-installation/3.upgrade-nebula-graph/upgrade-nebula-ent-from-3.x-3.4.md).
- The added property name can not be the same as an existing or deleted property name, otherwise, the operation of adding a property fails.
- Limit the type conversion when modifying the schema.
- The default value must be specified when creating a property of type `NOT NULL`.
- Add the multithreaded query parameter `query_concurrently` to the configuration file with a default value of `true`.
- Remove the parameter `kv_separation` of the KV separation storage function from the configuration file, which is turned off by default.
- Modify the default value of `local_config` in the configuration file to `true`.
- Consistent use of `v.tag.property` to get property values, because it is necessary to specify the Tag. Using `v.property` to access the property of a Tag on `v` was incorrectly allowed in the previous version.
- Remove the column `HTTP port` from the command `SHOW HOSTS`.
- Disable the queries of the form `OPTIONAL MATCH <pattern> WHERE <condition>`.
- Disable the functions of the form `COUNT(DISTINCT *)`.
- Disable TOSS.
- Rename Listener's pid filename and log directory name.
- Fix some crashes for the list function.

If you must use keywords in schema:

- Non-reserved keywords are permitted as identifiers without quoting.
- Non-reserved keywords can be used as identifiers without quotes if they are all in lowercase. However, if a non-reserved keyword contains any uppercase letters when used as an identifier, it must be enclosed in backticks (\`), for example, \`Comment\`.

- To use special characters or reserved keywords as identifiers, quote them with backticks such as `AND`.
