-The rank table is a JSON file that specifies the mapping of Ascend NPU ranks to nodes. For more details, please refer to the [vllm-ascend examples](https://github.com/vllm-project/vllm-ascend/blob/main/examples/disaggregated_prefill_v1/README.md). Execute the following commands for reference.

+## Install Mooncake
 
-|Parameter  | Meaning |
+Mooncake is the serving platform for Kimi, a leading LLM service provided by Moonshot AI. First, we need to obtain the Mooncake project. Refer to the following command:
-| --- | --- |
+
-| --ips | Each node's local IP address (prefiller nodes should be in front of decoder nodes) |
+```shell
-| --npus-per-node | Each node's NPU clips |
+git clone -b v0.3.7.post2 --depth 1 https://github.com/kvcache-ai/Mooncake.git
-| --network-card-name | The physical machines' NIC |
+```
-|--prefill-device-cnt  | NPU clips used for prefill |
+
-|--decode-device-cnt |NPU clips used for decode |
+(Optional) Replace go install url if the network is poor
+
+```shell
+cd Mooncake
+sed -i 's|https://go.dev/dl/|https://golang.google.cn/dl/|g' dependencies.sh
+```
+
+Install mpi
+
+```shell
+apt-get install mpich libmpich-dev -y
+```
+
+Install the relevant dependencies. The installation of Go is not required.
+
+```shell
+bash dependencies.sh -y
+```
+
+Compile and install
+
+```shell
+mkdir build
+cd build
+cmake .. -DUSE_ASCEND_DIRECT=ON
+make -j
+make install
+```
