+#### Using SentenceTransformer with numbered layers
+For models that have numbered SentenceTransformer layers (01_Pooling, 02_Dense,
+03_Dense, 04_Normalize), use the `-st` targets to apply all these layers:
+
+```console
+# Run original model with SentenceTransformer (applies all numbered layers)

+# Run converted model with pooling enabled
+(venv) $ make embedding-run-converted-model-st
+```
+
+This will use the SentenceTransformer library to load and run the model, which
+automatically applies all the numbered layers in the correct order. This is
+particularly useful when comparing with models that should include these
+additional transformation layers beyond just the base model output.

-Each host can run a different backend, e.g. one with CUDA and another with Metal.
-You can also run multiple `rpc-server` instances on the same host, each with a different backend.
+By default, `rpc-server` exposes all available accelerator devices on the host.
+If there are no accelerators, it exposes a single `CPU` device.
 
 ## Usage
 
-On each host, build the corresponding backend with `cmake` and add `-DGGML_RPC=ON` to the build options.
-For example, to build the CUDA backend with RPC support:
+### Remote hosts

+You can control the set of exposed CUDA devices with the `CUDA_VISIBLE_DEVICES` environment variable or the `--device` command line option. The following two commands have the same effect:
 ```bash
 $ CUDA_VISIBLE_DEVICES=0 bin/rpc-server -p 50052
+$ bin/rpc-server --device CUDA0 -p 50052
 ```
-This way you can run multiple `rpc-server` instances on the same host, each with a different CUDA device.
 
+### Main host
 
-On the main host build `llama.cpp` for the local backend and add `-DGGML_RPC=ON` to the build options.
-Finally, when running `llama-cli`, use the `--rpc` option to specify the host and port of each `rpc-server`:

 ```
 
-This way you can offload model layers to both local and remote devices.
+By default, llama.cpp distributes model weights and the KV cache across all available devices -- both local and remote -- in proportion to each device's available memory.
+You can override this behavior with the `--tensor-split` option and set custom proportions when splitting tensor data across devices.
