 ### Building Open-CE Python
 
-Open-CE Python can be built like any other Open-CE package. This repository contains [envs/python-env.yaml](https://github.com/open-ce/open-ce-python/blob/main/envs/python-env.yaml) which is to be used to build optimized python. The `open-ce` tool can be used to build this python. For more information on the `open-ce` tool, please see the Open-CE Builder [repository](https://github.com/open-ce/open-ce-builder).

This repository contains [envs/python-env.yaml](https://github.com/open-ce/open-ce-python/blob/main/envs/python-env.yaml) which is to be used to build optimized python.

For more information on the `open-ce` tool, please see the Open-CE Builder [repository](https://github.com/open-ce/open-ce-builder/blob/main/doc/README.open_ce_build.md).
 
 For example:
 ```shell
-    open-ce build env --python_versions=3.10 --ppc_arch=p10 --build_type=cpu python-env.yaml
+    open-ce build env --python_versions=3.10 --ppc_arch=p10 --output_folder=condabuild --build_type=cpu python-env.yaml
 ```
 
+### Using Open-CE python with other Open-CE packages
+
+One can use Open-CE packages along with the optimized Open-CE Python. Following are the steps to setup Open-CE Python and Open-CE packages in a single conda environment -
+
+1. Create a new conda environment with optimized python built as mentioned in above section.
+```shell
+    conda create -n <conda env name> python=3.10.9 -c file://<path to condabuild directory>
+```
+   Here, `path to condabuild directory` means the path to `--output_folder` when python was built as per above section.
+   If you have not specified `--output-folder` during the build, the directory will be `condabuild`.
+
+2. Activate the conda environment
+```shell
+    conda activate <conda env name>
+```
+
+3. Confirm the source of python package in the environment
+```shell
+    (<conda env name>)$ conda list python
+    # packages in environment at $HOME/anaconda3/envs/<conda env name>:
+    #
+    # Name                    Version                   Build  Channel
+    python                    3.10.9               hd70dfa7_0    file://<path to condabuild directory>
+```
+
+4. Install Open-CE packages from any of the following channels -
+
+   * https://anaconda.org/rocketce/
+   * https://ftp.osuosl.org/pub/open-ce/current/
+   * https://opence.mit.edu/
+
+For example:
+```shell
+    conda install -y tensorflow-cpu libtensorflow onnx onnxruntime pytorch-cpu openblas -c rocketce
+```
+
+5. Python Verification
+   When you're done with the package installation, run `(<conda env name>)$ conda list python` again to ensure that the python installed in the conda environment is not updated/replaced by any other python source like Anaconda.
