@@ -52,8 +52,10 @@ The `Unreleased` section name is replaced by the expected version of next releas
 - `Propulsion.CosmosStore.CosmosStoreSink`+`CosmosStorePruner`: Exposed `*Stats` [#226](https://github.com/jet/propulsion/pull/226)
 - `Propulsion.EventStore`: Pinned to target `Equinox.EventStore` v `[3.0.7`-`3.99.0]` **Deprecated; Please migrate to `Propulsion.EventStoreDb`** [#139](https://github.com/jet/propulsion/pull/139)
 - `Propulsion.EventStoreDb.EventStoreSource`: Changed API to match`Propulsion.SqlStreamStore` API rather than`Propulsion.EventStore` [#139](https://github.com/jet/propulsion/pull/139)
+- `Propulsion.Feed`: Moved implementations into main `Propulsion` library. While this adds a `FSharp.Control.TaskSeq` dependency, it makes maintenance and navigation easier

 ## Core Components
 
-- `Propulsion` [![NuGet](https://img.shields.io/nuget/v/Propulsion.svg)](https://www.nuget.org/packages/Propulsion/) Implements core functionality in a channel-independent fashion. [Depends](https://www.fuget.org/packages/Propulsion) on `MathNet.Numerics`
+- `Propulsion` [![NuGet](https://img.shields.io/nuget/v/Propulsion.svg)](https://www.nuget.org/packages/Propulsion/) Implements core functionality in a channel-independent fashion. [Depends](https://www.fuget.org/packages/Propulsion) on `Serilog`, `MathNet.Numerics`, `FSharp.Control.TaskSeq`:
 
     1. `StreamsSink`: High performance pipeline that handles parallelized event processing. Ingestion of events, and checkpointing of progress are handled asynchronously. Each aspect of the pipeline is decoupled such that it can be customized as desired. 
     2. `Streams.Prometheus`: Helper that exposes per-scheduler metrics for Prometheus scraping.
     3. `ParallelProjector`: Scaled down variant of `StreamsSink` that does not preserve stream level ordering semantics
+    4. `FeedSource`: Handles continual reading and checkpointing of events from a set of feeds ('tranches') of a 'source' that collectively represent a change data capture source for a given system (roughly analogous to how a CosmosDB Container presents a changefeed). A `readTranches` function is used to identify the Tranches (sub-feeds) on startup. The Feed Source then operates a logical reader thread per Tranche. Tranches represent content as an incrementally retrievable change feed consisting of batches of `FsCodec.ITimelineEvent` records. Each batch has an optional associated checkpointing callback that's triggered only when the Sink has handled all events within it.
+    5. `Monitor.AwaitCompletion`: Enables efficient waiting for completion of reaction processing within an integration test.
+    6. `PeriodicSource`: Handles regular crawling of an external datasource (such as a SQL database) where there is no way to save progress and then resume from that saved token (based on either the intrinsic properties of the data, or of the store itself). The source is expected to present its content as an `IAsyncEnumerable` of `FsCodec.StreamName * FsCodec.IEventData * context`. Checkpointing occurs only when all events have been deemed handled by the Sink.
+    7. `SinglePassFeedSource`: Handles single pass loading of large datasets (such as a SQL database), completing when the full data has been ingested.
+    8. `JsonSource`: Simple source that feeds items from a File containing JSON (such a file can be generated via `eqx query -o JSONFILE from cosmos` etc)
 
-- `Propulsion.Feed` [![NuGet](https://img.shields.io/nuget/v/Propulsion.Feed.svg)](https://www.nuget.org/packages/Propulsion.Feed/) Provides helpers for checkpointed consumption of a feed of stream-based inputs. Provides for custom bindings (e.g. a third-party Feed API) or various other input configurations (e.g. periodically correlating with inputs from a non-streamed source such as a SQL Database). Provides a generic API for checkpoint storage, with diverse implementations hosted in the sibling packages associated with each concrete store (supported stores include DynamoStore, CosmosStore, SQL Server, Postgres).
