+#### 🐳 Local Zabbix Environment
+For development and testing, you can start a complete environment including Zabbix from scratch:
+
+```bash
+# Start with local Zabbix (latest 7.0)
+docker compose --profile zabbix-local up -d
+
+# Start with a specific Zabbix version (e.g. 6.0)
+ZABBIX_VERSION=alpine-6.0-latest docker compose --profile zabbix-local up -d
+```
+
+> **Guide**: For detailed setup and configuration of the local environment, see [Local Development Environment](./docs/howtos/local_development.md).
+> **Important**: On fresh Zabbix installations, you must manually create the base host group (e.g., `Roadwork`) before the API can import devices.
+
 The API will be available at `http://localhost:4000/`.

+# 💻 Local Development Environment
+
+This guide provides detailed instructions on how to set up a fully isolated local development environment for the Zabbix GraphQL API using Docker Compose.
+
+## 🚀 Overview
+The project includes a Docker Compose profile that launches a complete Zabbix stack alongside the GraphQL API and MCP server. This allows you to develop and test features against different Zabbix versions without needing an external Zabbix installation.
+
+### Included Services
+- **`zabbix-graphql-api`**: The main GraphQL server.
+- **`apollo-mcp-server`**: The Model Context Protocol server for AI integration.
+- **`postgres-server`**: PostgreSQL 16 database for Zabbix.
+- **`zabbix-server`**: Zabbix Server (PostgreSQL version).
+- **`zabbix-web`**: Zabbix Web interface (Nginx/PostgreSQL).
+
+## 🛠️ Step-by-Step Setup
+
+### 1. Start the Environment
+Use the `zabbix-local` profile to start all services. You can optionally specify the Zabbix version using the `ZABBIX_VERSION` environment variable.
+
+```bash
+# Start the latest 7.0 (default)
+docker compose --profile zabbix-local up -d
+
+# Start Zabbix 6.0 (LTS)
+ZABBIX_VERSION=alpine-6.0-latest docker compose --profile zabbix-local up -d
+```
+
+### 2. Configure Zabbix
+Once the containers are running, you need to perform a minimal setup in the Zabbix UI:
+
+1. Open `http://localhost:8080` in your browser.
+2. Log in with the default credentials:
+   - **User**: `Admin`
+   - **Password**: `zabbix`
+3. Navigate to **Administration** > **Users** > **API tokens**.
+4. Create a new token for the `Admin` user (or a dedicated service user) and copy it.
+5. **Create Base Host Group**: The API requires a base host group to exist for importing devices.
+   - Navigate to **Configuration** > **Host groups** (or **Data collection** > **Host groups** in Zabbix 7.0).
+   - Create a host group named `Roadwork` (or the value of `ZABBIX_EDGE_DEVICE_BASE_GROUP` in your `.env`).
+   - **Note**: If your base group is nested (e.g., `Roadwork/Devices`), ensure the full path exists. Zabbix does not automatically create parent groups when creating child groups via the API.
+
+### 3. Connect the API
+To connect the GraphQL API to your local Zabbix instance, update your `.env` file with the following values (referenced in `samples/zabbix-local.env`):
+
+```env
+# Internal Docker network URL
+ZABBIX_BASE_URL=http://zabbix-web:8080/
+
+# The token you created in Step 2
+ZABBIX_PRIVILEGE_ESCALATION_TOKEN=your-newly-created-token
+```
+
+### 4. Restart the API
+Apply the configuration by restarting the API container:
+
+```bash
+docker compose restart zabbix-graphql-api
+```
+
+## ✅ Verification
+You can verify the setup by running a simple query against the local API:
+
+```bash
+curl -X POST -H "Content-Type: application/json" \
+  -d '{"query": "{ apiVersion zabbixVersion }"}' \
+  http://localhost:4001/
+```
+
+The `zabbixVersion` should match the version you specified in `ZABBIX_VERSION`.
+
+## 💡 Advanced Usage
+
+### Data Persistence
+Zabbix data is stored in a named Docker volume called `zbx_db_data`. This ensures that your configuration, templates, and hosts are preserved even if you stop or remove the containers.
+
+To perform a clean reset of the environment:
+```bash
+docker compose --profile zabbix-local down -v
+```
+
+### Testing Multiple Versions
+The local environment is perfect for testing the API's version-specific logic (e.g. `history.push` vs `zabbix_sender`). Simply change the `ZABBIX_VERSION` variable and restart the stack.
+
+Supported tags can be found on the [Zabbix Docker Hub](https://hub.docker.com/u/zabbix).

+#### Local Development Setup
+For running integration tests against a real Zabbix instance, it is recommended to use the [Local Development Environment](./local_development.md). This setup allows you to test the API against specific Zabbix versions (e.g. 6.0, 7.0) in an isolated way.
+
 #### Adding New Tests
 - **Location**: Place new test files in `src/test/` with the `.test.ts` extension.
 - **Coverage**: Ensure you cover both successful operations and error scenarios.

+  - *Feature*: Support for multiple Zabbix versions (6.0, 6.4, 7.0+) for development and testing.
+  - *Implementation*: Added `zabbix-local` profile and `ZABBIX_VERSION` dynamic image tagging.
+
+- **🔧 Multi-Version Compatibility**: Verified and enhanced support for Zabbix 6.0 LTS, 6.2, 6.4, and 7.0 LTS.

 - **🏗️ Trade Fair Logistics Use Case**: Extend the API to support trade fair logistics use cases by analyzing requirements from business stakeholders.
   - *Analysis*: Analysis of "Trade Fair Logistics" and derived [requirements document](docs/use-cases/trade-fair-logistics-requirements.md).
