 ## Install
 
+The recommended way of using this package is through the latest container produced by Bioconda [here](https://quay.io/repository/biocontainers/scanpy-scripts?tab=tags). If you must, one can install scanpy-scripts via conda:
+
 ```bash
 conda install scanpy-scripts
-# or
-pip3 install scanpy-scripts
 ```
 
+pip installation is also possible, however the version of mnnpy is not patched as in the conda version, and so the `integrate` command will not work.
+
+```bash
+pip install scanpy-scripts
+```
+
+For development installation, we suggest following the github actions python-package.yml file.
+
+Currently, tests run on python 3.9, so those are the recommended versions if not installing via conda. BKNN doesn't currently install on Python 3.10 due to a skip in Bioconda.
