 ### Deployment types
 
-CLP supports multiple deployment configurations based on the compression scheduler and query engine.
+CLP supports two deployment configurations, depending on the query engine:
 
-| Deployment Type | Compression Scheduler | Query Engine                 |
-|-----------------|-----------------------|------------------------------|
-| Base            | Celery                | [Presto][presto-integration] |
-| Full            | Celery                | Native                       |
-| Spider Base     | Spider                | [Presto][presto-integration] |
-| Spider Full     | Spider                | Native                       |
+* **Full**: Uses Celery for query orchestration.
+* **Base**: Excludes the Celery-based query orchestration in Full, to support the
+  [Presto integration][presto-integration].
 
-:::{note}
-Spider support is not yet available for Helm.

-Docker Compose selects the appropriate compose file (e.g., `docker-compose.yaml` for Full,
-`docker-compose-spider.yaml` for Spider Full) and uses `deploy.replicas` with environment
-variables (e.g., `CLP_MCP_SERVER_ENABLED`) to toggle optional services. Helm uses conditional
-templating to include/exclude resources.

-# Using Spider with CLP
-
-[Spider] is a fast and scalable distributed task execution engine that can be used to run tasks.
-This guide describes how to set up and use Spider with CLP.
-
-:::{note}
-Spider is under active development, and its integration with CLP may change in the future.
-Right now, Spider only supports executing CLP compression tasks. Support for search tasks will be added
-later.
-:::
-
-## Requirements
-
-* [CLP][clp-releases] v0.8.0 or higher
-* [Docker] v28 or higher
-* [Docker Compose][docker-compose] v2.20.2 or higher
-
-## Set up
-
-To use Spider for CLP compression tasks, you need to [set up CLP](#setting-up-clp-with-spider) with
-Spider in configuration.
-
-### Setting up CLP with Spider
-
-1. Follow the [quick-start](quick-start/index.md) guide to download and extract the CLP package,
-   but don't start the package just yet.
-2. Before starting the package, update the package's config file (`etc/clp-config.yaml`) as follows:
-
-    * Change the `compression_scheduler.type` field to `"spider"`.
-
-      ```yaml
-      compression_scheduler:
-        type: "spider"
-      ```
-
-    * (Optional) Override `database.names.spider` to avoid name conflicts when using self-provisioned database instances.
-
-        ```yaml
-        database:
-            names:
-                spider: "spider-db"
-        ```
-
-    * (Optional) Override the `spider_scheduler` default config to change listening host or avoid port conflicts.
-
-        ```yaml
-        spider_scheduler:
-            host: "localhost"
-            port: 6000
-        ```
-
-3. (Optional) If you do not intend to use generated credentials, set your own Spider credentials in
-   `etc/credentials.yaml` before starting the package.
-
-    ```yaml
-    database:
-      spider_username: "spider-user"
-      spider_password: "spider-pass"
-    ```
-
-4. Continue following the [quick-start](./quick-start/index.md#using-clp) guide to start CLP.
