+
+This project provides a tiny C++ profiling library for monitoring:
+* execution time
+* CPU usage
+* memory usage
+* GPU usage and memory
+
+This library aims at collecting metrics on embedded devices to monitor device
+performance while operating heavy tasks or booting for example. Those metrics can
+be useful to check that load is properly spread onto all CPU cores or
+that memory is not starved.
+
+This library can also run on non-embedded devices like servers or desktop PCs. It is
+compatible with Linux and Windows.
+
+Metrics are stored in a CSV file (the path is configurable).
+
+## Usage
+
+The library is lightweight, simple and easy to use. It can be easily used from an existing application or integrated in a dedicated monitoring application.
+
+Full API documentation is available [here](https://orange-opensource.github.io/cppuprofile/).
+
+### System memory and CPU usage monitoring
+
+```cpp
+#include <uprofile/uprofile.h>
+...
+uprofile::start("uprofile.log");
+uprofile::startSystemMemoryMonitoring(200);
+uprofile::startCPUUsageMonitoring(200);
+...
+uprofile::stop();
+```
+
+### Record time execution
+
+```cpp
+uprofile::timeBegin("my_custom_function");
+...
+uprofile::timeEnd("my_custom_function");
+```
+
+### GPU monitoring
+
+The library also supports GPU metrics monitoring like usage and memory. Since GPU monitoring is specific to each vendor, an interface `IGPUMonitor` is available to abstract each vendor monitor system.
+
+To monitor a specific GPU, you must subclass `IGPUMonitor`:
+
+```cpp
+#include <uprofile/igpumonitor.h>
+
+class MyGPUMonitor: public uprofile::IGPUMonitor {
+public:
+    float getUsage() override;
+    void getMemory(int& usedMem, int& totalMem) override;
+}
+```
+
+And then inject it at runtime to the `uprofile` monitoring system:
+
+```cpp
+uprofile::addGPUMonitor(new MyGPUMonitor);
+uprofile::start("uprofile.log");
+uprofile::startGPUMemoryMonitoring(200);
+uprofile::startGPUUsageMonitoring(200);
+```
+
+#### Supported GPU monitoring
+
+Here is the list of GPUs supported by `cppuprofile`
+
+* NVidia Graphics Cards (through `nvidia-smi`). Pass `-DGPU_MONITOR_NVIDIA=ON` as compile option and inject `uprofile::NvidiaMonitor` from `monitors/nvidiamonitor.h` as `GPUMonitor`. The `nvidia-smi` tool should be installed into `/usr/bin` directory.
+
+## Build
+
+The build process is based on CMake. Minimum version is 2.8.
+
+```commandline
+$ cmake --configure . -B ../build-cppuprofile
+$ cmake --build ../build-cppuprofile
+```
+
+### Shared/dynamic library
+
+By default, it generates a shared library on Linux and a dynamic library (DLL) on Windows. To link with this library on Windows, you must
+pass `-DUPROFILE_DLL` definition to CMake.
+
+### Static library
+
+If you want to generate a static library, you must use `-DBUILD_SHARED_LIBS=OFF` CMake option.
+
+### Disable profiling in Release mode
+
+If you want to disable profiling in Release mode or if you want to only enable profiling in particular cases, you can use the `PROFILE_ENABLED` option (set to `ON` by default).
+
+To disable the profiling:
+
+```commandline
+$ cmake --configure . -B ../build-cppuprofile -DPROFILE_ENABLED=OFF
+```
+
+## Tools
+
+The project also brings a tool for displaying the different metrics in
+a single view:
+
+![ScreenshotShowGraph](doc/show-graph-screenshot.png)
+
+This tool is written in Python3. It requires a set of dependency packages. To install them:
+
+```commandline
+$ pip3 install -r requirements.txt
+```
+
+Then
+
+```commandline
+$ ./tools/show-graph uprofile.log
+```
+
+Note that you can filter the metrics to display with `--metric` argument.
+
+## Sample
+
+The project provides a C++ sample application called `uprof-sample`
+that shows how to use the `cppuprofile` library. You can build it with `SAMPLE_ENABLED` option:
+
+```commandline
+$ cmake --configure . -B ../build-cppuprofile -DSAMPLE_ENABLED=ON
+$ cmake --build ../build-cppuprofile
+$ ../build-cppuprofile/sample/uprof-sample
+```
+
+## Windows support limitations
+
+The library compiles on Windows but only time execution is supported so far. Monitoring metrics like CPU Usage and system, process and nvidia GPU memory are not supported.
+
+Contributions are welcomed.
