 Install
 -------
 
 Once you have [PostgresSQL](http://www.postgresql.org/download/) and [redis](https://pypi.python.org/pypi/redis/) installed (follow the instruction on their web site), simply run these commands to install qiita and configure the demo environment, replacing $QIITA_DIR for the path where qiita is installed
-(note that if you are not using Ubuntu you might need to follow the instructions in the next section):
+(note that if you are not using Ubuntu you might need to follow the instructions in the next section).
 
 ```bash
-echo "export QIITA_CONFIG_FP=$QIITA_DIR/qiita_core/support_files/config_demo.txt" >> ~/.bashrc
+pip install numpy
+pip install cogent burrito qcli emperor pyzmq
+pip install https://github.com/biocore/qiime/archive/master.zip --no-deps
+pip install qiita
+```
+
+After these commands are executed, you will need (1) download a [sample Qiita configuration file](https://raw.githubusercontent.com/biocore/qiita/a0628e54aef85b1a064d40d57ca981aaf082a120/qiita_core/support_files/config_test.txt), (2) set the `QIITA_CONFIG_FP` environment variable and (3) proceed to initialize your environment:
+
+```bash
+# (1) use curl -O if using OS X
+wget https://github.com/biocore/qiita/blob/a0628e54aef85b1a064d40d57ca981aaf082a120/qiita_core/support_files/config_test.txt
+# (2) set the enviroment variable in your .bashrc
+echo "export QIITA_CONFIG_FP=config_test.txt" >> ~/.bashrc
 source ~/.bashrc
-pip install https://github.com/biocore/qiita/archive/master.zip
-qiita_env make_env --env demo
+# (3) start a test environment
+qiita_env make --no-load-ontologies --add-demo-user
 ```
+
+Finally you need to start the server:
+
+```bash
+# IPython takes a while to get initialized so wait 30 seconds
+qiita_env start_cluster demo test reserved && sleep 30
+qiita webserver start
+
+```
+
+If all the above commands executed correctly, you should be able to go to http://localhost:8888 in your browser, to login use `demo@microbio.me` and `password` as the credentials.

 You will need to add the postgres user to the database. In order to do this, run:
