@@ -15,15 +15,18 @@ Your application can call location-specific APIs to obtain the location informat
 Location awareness helps determine where a mobile device locates. The system identifies the location of a mobile device with its coordinates, and uses location technologies such as Global Navigation Satellite System (GNSS) and network positioning (for example, base station positioning or WLAN/Bluetooth positioning) to provide diverse location-based services. These advanced location technologies make it possible to obtain the accurate location of the mobile device, regardless of whether it is indoors or outdoors.
 
 - **Coordinate**
+
   A coordinate describes a location on the earth using the longitude and latitude in reference to the World Geodetic Coordinate System 1984.
 
 - **GNSS positioning**
   GNSS positioning locates a mobile device by using the location algorithm offered by the device chip to compute the location information provided by the Global Navigation Satellite System, for example, GPS, GLONASS, BeiDou, and Galileo. Whichever positioning system will be used during the location process depends on a hardware capability of the device.
 
 - **Base station positioning**
+
   Base station positioning estimates the current location of a mobile device based on the location of the resident base station in reference to the neighboring base stations. This technology provides only a low accuracy and requires access to the cellular network.
 
 - **WLAN or Bluetooth positioning**
+
   WLAN or Bluetooth positioning estimates the current location of a mobile device based on the locations of WLANs and Bluetooth devices that can be discovered by the device. The location accuracy of this technology depends on the distribution of fixed WLAN access points (APs) and Bluetooth devices around the device. A high density of WLAN APs and Bluetooth devices can produce a more accurate location result than base station positioning. This technology also requires access to the network.

+# Using MindSpore Lite for Model Inference
+
+## When to Use
+
+MindSpore Lite is an AI engine that provides AI model inference for different hardware devices. It has been used in a wide range of fields, such as image classification, target recognition, facial recognition, and character recognition.
+
+This document describes the general development process for MindSpore Lite model inference.
+
+## Basic Concepts
+
+Before getting started, you need to understand the following basic concepts:
+
+**Tensor**: a special data structure that is similar to arrays and matrices. It is a basic data structure used in MindSpore Lite network operations.
+
+**Float16 inference**: a mode in which Float16 is used for inference. Float16, also called half-precision, uses 16 bits to represent a number. 
+
+
+
+## Available APIs
+APIs involved in MindSpore Lite model inference are categorized into context APIs, model APIs, and tensor APIs.
+### Context APIs
+
+| API       | Description       |
+| ------------------ | ----------------- |
+|OH_AI_ContextHandle OH_AI_ContextCreate()|Creates a context object.|
+|void OH_AI_ContextSetThreadNum(OH_AI_ContextHandle context, int32_t thread_num)|Sets the number of runtime threads.|
+| void OH_AI_ContextSetThreadAffinityMode(OH_AI_ContextHandle context, int mode)|Sets the affinity mode for binding runtime threads to CPU cores, which are categorized into little cores and big cores depending on the CPU frequency.|

+|OH_AI_ModelHandle OH_AI_ModelCreate()|Creates a model object.|
+|OH_AI_Status OH_AI_ModelBuildFromFile(OH_AI_ModelHandle model, const char *model_path,OH_AI_ModelType odel_type, const OH_AI_ContextHandle model_context)|Loads and builds a MindSpore model from a model file.|
+|void OH_AI_ModelDestroy(OH_AI_ModelHandle *model)|Destroys a model object.|
+
+### Tensor APIs
+
+| API       | Description       |
+| ------------------ | ----------------- |

+
+## How to Develop
+The following figure shows the development process for MindSpore Lite model inference.
+
+**Figure 1** Development process for MindSpore Lite model inference
+![how-to-use-mindspore-lite](figures/01.png)
+
+The development process consists of the following main steps:
+
+1. Prepare the required model.
+
+    The required model can be downloaded directly or obtained using the model conversion tool.
+  
+     - If the downloaded model is in the `.ms` format, you can use it directly for inference. The following uses the **mobilenetv2.ms** model as an example.
+     - If the downloaded model uses a third-party framework, such as TensorFlow, TensorFlow Lite, Caffe, or ONNX, you can use the [model conversion tool](https://www.mindspore.cn/lite/docs/en/r1.5/use/benchmark_tool.html) to convert it to the `.ms` format.
+
+2. Create a context, and set parameters such as the number of runtime threads and device type.
+  
+    ```c
+    // Create a context, and set the number of runtime threads to 2 and the thread affinity mode to 1 (big cores first).
+    OH_AI_ContextHandle context = OH_AI_ContextCreate();
+    if (context == NULL) {
+      printf("OH_AI_ContextCreate failed.\n");
+      return OH_AI_STATUS_LITE_ERROR;
+    }
+    const int thread_num = 2;
+    OH_AI_ContextSetThreadNum(context, thread_num);
+    OH_AI_ContextSetThreadAffinityMode(context, 1);
+    // Set the device type to CPU, and disable Float16 inference.
+    OH_AI_DeviceInfoHandle cpu_device_info = OH_AI_DeviceInfoCreate(OH_AI_DEVICETYPE_CPU);
+    if (cpu_device_info == NULL) {
+      printf("OH_AI_DeviceInfoCreate failed.\n");
+      OH_AI_ContextDestroy(&context);
+      return OH_AI_STATUS_LITE_ERROR;
+    }
+    OH_AI_DeviceInfoSetEnableFP16(cpu_device_info, false);
+    OH_AI_ContextAddDeviceInfo(context, cpu_device_info);
+    ```
+
+3. Create, load, and build the model.
+
+    Call **OH_AI_ModelBuildFromFile** to load and build the model.
+
+    In this example, the **argv[1]** parameter passed to **OH_AI_ModelBuildFromFile** indicates the specified model file path.
+
+    ```c
+    // Create a model.
+    OH_AI_ModelHandle model = OH_AI_ModelCreate();
+    if (model == NULL) {
+      printf("OH_AI_ModelCreate failed.\n");
+      OH_AI_ContextDestroy(&context);
+      return OH_AI_STATUS_LITE_ERROR;
+    }
+
+    // Load and build the model. The model type is OH_AI_ModelTypeMindIR.
+    int ret = OH_AI_ModelBuildFromFile(model, argv[1], OH_AI_ModelTypeMindIR, context);
+    if (ret != OH_AI_STATUS_SUCCESS) {
+      printf("OH_AI_ModelBuildFromFile failed, ret: %d.\n", ret);
+      OH_AI_ModelDestroy(&model);
+      return ret;
+    }
+    ```
+
+4. Input data.
+ 
+    Before executing model inference, you need to populate data to the input tensor. In this example, random data is used to populate the model.
+
+    ```c
+    // Obtain the input tensor.
+    OH_AI_TensorHandleArray inputs = OH_AI_ModelGetInputs(model);
+    if (inputs.handle_list == NULL) {
+      printf("OH_AI_ModelGetInputs failed, ret: %d.\n", ret);
+      OH_AI_ModelDestroy(&model);
+      return ret;
+    }
+    // Use random data to populate the tensor.
+    ret = GenerateInputDataWithRandom(inputs);
+    if (ret != OH_AI_STATUS_SUCCESS) {
+      printf("GenerateInputDataWithRandom failed, ret: %d.\n", ret);
+      OH_AI_ModelDestroy(&model);
+      return ret;
+    }
+   ```
+
+5. Execute model inference.
+
+    Call **OH_AI_ModelPredict** to perform model inference.
+
+    ```c
+    // Execute model inference.
+    OH_AI_TensorHandleArray outputs;
+    ret = OH_AI_ModelPredict(model, inputs, &outputs, NULL, NULL);
+    if (ret != OH_AI_STATUS_SUCCESS) {
+      printf("OH_AI_ModelPredict failed, ret: %d.\n", ret);
+      OH_AI_ModelDestroy(&model);
+      return ret;
+    }
+    ```
+
+6. Obtain the output.
+
+    After model inference is complete, you can obtain the inference result through the output tensor.
+
+    ```c
+    // Obtain the output tensor and print the information.
+    for (size_t i = 0; i < outputs.handle_num; ++i) {
+      OH_AI_TensorHandle tensor = outputs.handle_list[i];
+      int64_t element_num = OH_AI_TensorGetElementNum(tensor);
+      printf("Tensor name: %s, tensor size is %zu ,elements num: %lld.\n", OH_AI_TensorGetName(tensor),
+            OH_AI_TensorGetDataSize(tensor), element_num);
+      const float *data = (const float *)OH_AI_TensorGetData(tensor);
+      printf("output data is:\n");
+      const int max_print_num = 50;
+      for (int j = 0; j < element_num && j <= max_print_num; ++j) {
+        printf("%f ", data[j]);
+      }
+      printf("\n");
+    }
+    ```
+
+7. Destroy the model.
+
+    If the MindSpore Lite inference framework is no longer needed, you need to destroy the created model.
+
+    ```c
+    // Destroy the model.
+    OH_AI_ModelDestroy(&model);
+    ```
+
+## Verification
+
+1. Compile **CMakeLists.txt**.
+
+    ```cmake
+    cmake_minimum_required(VERSION 3.14)
+    project(Demo)
+
+    add_executable(demo main.c)
+
+    target_link_libraries(
+            demo
+            mindspore-lite.huawei
+            pthread
+            dl
+    )
+    ```
+   - To use ohos-sdk for cross compilation, you need to set the native toolchain path for the CMake tool as follows: `-DCMAKE_TOOLCHAIN_FILE="/xxx/ohos-sdk/linux/native/build/cmake/ohos.toolchain.cmake"`.
+    
+   - The toolchain builds a 64-bit application by default. To build a 32-bit application, add the following configuration: `-DOHOS_ARCH="armeabi-v7a"`.
+
+2. Run the CMake tool.
+
+    - Use hdc_std to connect to the RK3568 development board and put **demo** and **mobilenetv2.ms** to the same directory on the board.
+    - Run the hdc_std shell command to access the development board, go to the directory where **demo** is located, and run the following command:
+
+    ```shell
+    ./demo mobilenetv2.ms
+    ```
+
+    The inference is successful if the output is similar to the following:
+
+    ```shell
+    # ./QuickStart ./mobilenetv2.ms                                            
+    Tensor name: Softmax-65, tensor size is 4004 ,elements num: 1001.
+    output data is:

-# User File Access and Management
-
-The **fileManager** module provides APIs for accessing and managing user files. It interworks with the underlying file management services to implement media library and external card management, and provides capabilities for applications to query and create user files.
-
->**NOTE**<br/>
->
->- The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
->- The APIs of this module are system APIs and cannot be called by third-party applications. Currently, these APIs can be called only by **filepicker**.
