+# Exploration of different user levers for demand response in data centers
+## List of experiments
+- TODO
+
+## Install
+Clone the repository
+
+```bash
+git clone https://gitlab.irit.fr/sepia-pub/open-science/demand-response-user.git
+```
+
+For reproducible experiments, all the dependancies for these experiments and their version (batsim, batshed, python3 with packages, ...) are managed with `nix` package manager. To install `nix`: 
+
+```bash
+curl -L https://nixos.org/nix/install | sh
+```
+
+
+## Start the simulation environment
+TODO
+``` bash
+nix-shell --pure ./env_nix.nix --show-trace #start the shell
+jupyter notebook                            #open jupyter notebook
