+# CLP TDL Package
+
+This component contains implementations of CLP tasks that run on Spider. It provides a shared
+library that conforms to Spider's Task Definition Language (TDL) package specification.
+
+## Tasks
+
+This component bundles all supported CLP tasks into a single TDL package. The available tasks are
+documented below.
+
+### Compression
+
+* `compression::clp_s_s3_compress`: Compress inputs from S3 using `clp-s`.
+* `compression::commit`: Commit compression task outcomes to the CLP metadata database.

 ### Deployment types
 
-CLP supports two deployment configurations, depending on the query engine:
+CLP supports four deployment configurations, determined by two independent choices: the query engine
+(Celery or Presto), and whether Spider is enabled.
+
+The query engine determines how queries are orchestrated:
 
 * **Full**: Uses Celery for query orchestration.
 * **Base**: Excludes the Celery-based query orchestration in Full, to support the
   [Presto integration][presto-integration].
 
+Enabling Spider adds the `compression-coordinator` service, which routes compression jobs to be
+driven by Spider instead of Celery. This choice is orthogonal to the query engine: queries are still
+driven by Celery or Presto according to the deployment type.
+
+:::{note}
+The Celery-based `compression-scheduler` will be deprecated in a future release to be fully replaced
+by `compression-coordinator` and Spider. However, it still remains enabled by default since the
+current `compression-coordinator` implementation can only coordinate compression jobs created by
+`log-ingestor`.
