+## Getting started
+
+### Install packages
+
+1. Install [miniconda3](https://docs.conda.io/en/latest/miniconda.html).
+2. Install the `voltctrl` conda environment:
+    ```bash
+    conda env update -f env.yml --prune
+    ```
+3. Request a Mosek license ([link](https://www.mosek.com/products/academic-licenses/)). Upon receiving the license file (`mosek.lic`) in an email, create a folder `~/mosek` and copy the license file into that folder.

 ## Data Files (in `/data`)
 
 The original data files were provided by the authors of the following paper:

-The original data files ("orig_data.zip") are attached to the [releases](https://github.com/chrisyeh96/voltctrl/releases/tag/v1.0). These original data files have been processed into the following files, which are the only files relevant for our experiments. See the inspect_matlab_data.ipynb notebook for details.
