 # fd-yellowstone
 
-The firedancer/fd-yellowstone repository
-(https://github.com/firedancer-io/fd-yellowstone) is a sample geyser
-implementation for the full firedancer client. It is meant to mimic
-https://github.com/rpcpool/yellowstone-grpc.git .
-
-To build:
-1. Clone the repo under src/app in the firedancer source tree. For
-example:
-* cd firedancer/src/app
-* git clone https://github.com/firedancer-io/fd-yellowstone
-2. Install grpc (https://github.com/grpc/grpc) somewhere.
-3. Tweak the PKG variable in Local.mk and Makefile to correspond to
-your grpc installation.
-4. Build firedancer normally. You should see a new executable
-fd_grpc_geyser in the bin directory.
-5. Run the firedancer full client. _Wait until it is processing blocks._
-6. In another window, run "fd_grpc_geyser". The --port flag can
-specify the service port.
-7. Try the unit test (unit-test/test_geyser_client) The --target flag
-specifies host:port.
+The [fd-yellowstone repository](https://github.com/firedancer-io/fd-yellowstone) is a sample geyser implementation for the full firedancer client.
+It is meant to mimic the [original yellowstone-grpc](https://github.com/rpcpool/yellowstone-grpc).
+
+## Build
+
+1. Clone the repo under `src/app` in the **firedancer** source tree.
+For example:
+
+```console
+$ cd firedancer/src/app
+$ git clone https://github.com/firedancer-io/fd-yellowstone
+```
+
+2. Install [grpc](https://github.com/grpc/grpc) somewhere.
+3. Tweak the `PKG` and `PROTOS_PATH` variables in `Local.mk` and `Makefile` to correspond to your grpc installation.
+4. Build **firedancer** normally. You should see a new executable
+`fd_grpc_geyser` in the `bin` directory.
+
+## Run
+
+1. Run the **firedancer** full client. _Wait until it is processing blocks._
+2. In another window, run `fd_grpc_geyser`.
+Available flags are:
+
+| Flag                | Default                 | Description                 |
+| ------------------- | ----------------------- | --------------------------- |
+| `--port`            | 8754                    | Server port for the service |
+| `--funk_wksp`       | "fd1_funk.wksp"         | Funk workspace              |
+| `--blockstore_wksp` | "fd1_blockstore.wksp"   | Blockstore workspace        |
+| `--notify_wksp`     | "fd1_replay_notif.wksp" | Notification link workspace |
+
+## Testing
+
+Try the unit test `unit-test/test_geyser_client`
+
+| Flag       | Default          | Description    |
+| ---------- | ---------------- | -------------- |
+| `--target` | "localhost:8754" | Server address |
