+## Notes
 The `environment.yml` file should list all Python libraries on which your notebooks
 depend, specified as though they were created using the following `conda` commands:
 
 ```
-source activate example-environment
-conda env export > environment.yml
+conda activate example-environment
+conda env export --from-history -f environment.yml
 ```
 
 Note that the only libraries available to you will be the ones specified in
-the `environment.yml`, so be sure to include everything that you need!
+the `environment.yml`, so be sure to include everything that you need! 
+
+Also note that if you skip the `--from-history`, conda may include OS-specific
+packages in `environment.yml`, which you would have to manually prune from
+`environment.yml`.  For example, confirmed macOS-specific packages that should
+be removed are:
+
+* libcxxabi=4.0.1
+* appnope=0.1.0
+* libgfortran=3.0.1
+* libcxx=4.0.1
