 ### Creating an isolated conda environment
 Run the following commands to create a self-contained dev environment for CSM-CameraModel (type `y` to confirm creation):
 ```bash
 conda create -n csmdev -c usgs-astrogeology cmake libcsm

-#### Activating the environment
+### Activating the environment
 After creating the `csmdev` environment and installing cmake and libcsm into it, we need to activate it. Right now, cmake, libcsm, and their dependencies are isolated to a conda environment and we need to tell conda that we want to use it. The activation command depends on your shell.
 * **bash**: `source activate csmdev`
 * **tcsh**: `conda activate csmdev`
+> *You can add these to the end of your $HOME/.bashrc or $HOME/.cshrc if you want the `csmdev` environment to be active in every new terminal.*
 
+## Building CSM-CameraModel
 After you've set up conda, you can build CSM-CameraModel:
 
 1. Fork `USGS-Astrogeology/CSM-CameraModel` if you don't already have a fork.
