 ### Creating the `environment.yml` file
 
-[tbd] 
+In order to ensure that the user of your source code can **exactly** reproduce your published experimental results, you want to ensure that they are working in the **same environment.**  This means that the user should be working with the same versions of all the Python/Bob packages and package dependencies that you used when running your experiments.  An easy way to achieve this is to **freeze** your working environment into an `environment.yml` file, from which the user can then re-create the same working environment.  To do this, execute the following commands in your terminal, replacing `bob.paper.isba2018_entropy` with the name of your project and `bob.paper.isba2018_entropy.env` with the name of your conda environment:
+
+```sh
+$ cd bob.paper.isba2018_entropy
+$ source activate bob.paper.isba2018_entropy.env
+$ conda env export > environment.yml
+```
+And that's it!  All you need to do now is to include `environment.yml` in your `MANIFEST.in` file to make sure that your environment file is packaged along with your source code (when creating a PyPI package).
