+## Build from Sources with `conda-build`
+
+Intel(R) Extension for Scikit-learn* is easily built from the sources using only one command and `conda-build` utility. 
+
+### Prerequisites for `conda-build`
+
+* any `conda` distribution (`miniforge` is recommended)
+* `conda-build` and `conda-verify` installed in a conda environment
+* (Windows only) Microsoft Visual Studio*
+* (optional) Intel(R) oneAPI DPC++/C++ Compiler
+
+`conda-build` config requires **2022** version of Microsoft Visual Studio* by default, you can specify another version in `conda-recipe/conda_build_config.yaml` if needed.
+
+In order to enable DPC++ interfaces support on Windows, you need to set `DPCPPROOT` environment variable pointing to DPC++/C++ Compiler distribution.
+Conda-forge distribution of DPC++ compiler is used by default on Linux, but you still can set your own distribution via `DPCPPROOT` variable.
+
+### Build Intel(R) Extension for Scikit-learn with `conda-build`
+
+Create and verify `scikit-learn-intelex` conda package with next command executed from root of sklearnex repo:
+
+```bash
+conda build .
+```
