+### Installation note: nmslib
+Over the years, installing nmslib has becomes quite difficult. There are a number of GitHub issues on scispaCy and the nmslib repo itself about this. This matrix is an attempt to help users install nmslib in whatever environment they have. I don't have access to every type of environment, so if you are able to test something out, please open an issue or pull request!

 version of Python required for scispaCy.  If you already have a Python
 environment you want to use, you can skip to the 'installing via pip' section.

+1.  [Follow the installation instructions for Mamba](https://mamba.readthedocs.io/en/latest/installation/mamba-installation.html).
 
 2.  Create a Conda environment called "scispacy" with Python 3.9 (any version >= 3.6 should work):
 
     ```bash
-    conda create -n scispacy python=3.9
+    mamba create -n scispacy python=3.10
     ```
 
-3.  Activate the Conda environment. You will need to activate the Conda environment in each terminal in which you want to use scispaCy.
+3.  Activate the Mamba environment. You will need to activate the Conda environment in each terminal in which you want to use scispaCy.
 
     ```bash
-    source activate scispacy
+    mamba activate scispacy
     ```
 
 Now you can install `scispacy` and one of the models using the steps above.
