 Notice how your prompt is now prefixed with the name of your environment (''project_1_env'', in this case). This is the indicator that ''project_1_env'' is currently active, which means <color #ed1c24>the python executable will only use this environment’s packages and settings.</color>
+Now you can use pip to install packages (large packages may take a while to install).
 To go back to the “system” context, execute a deactivate:

 Now your shell session is back to normal, and the python command refers to the global Python install. Remember to do this whenever you’re done using a specific virtual environment.
-===== Using a Python3 IDE with Virtual Environments =====
+Using Virtual Environment makes it east to reset your Python environment if you need to use a different set of packages.  Just delete the old environment and create a new one.

+===== Tips for Using a Python3 IDE with Virtual Environments =====
+==== Using Spyder in the 244 Lab ====
   - Activate (start) your virtual environment.
-  - Run spyder from the environment (after source activate)
+  - Run spyder
-  - Go to Tools --> preferences --> python Interpreter and select the python file from the env you want to link to spyder ex : /home/you/envs/your_env/bin/python
+  - Go to Tools --> preferences --> python Interpreter and select the python file from the virtual env you want to link to Spyder ex : /home/you/envs/your_env/bin/python
-=== Spyder Method 2 (Use with tensorflo) ===
+==== Preferred Method on Research Computers: Spyder Method 1 (Use with tensorflow) ====
 To use Spyder.
   - Activate (start) your virtual environment.
+  - Install the needed packages with pip
   - Install Spyder into your environment using pip install spyder.
   - Then start spyder from the environment command line with the command spyder.
