 If no version of `conda` is detected, it will install [miniconda](https://conda.io/miniconda.html), which we use for managing dependencies and creating a virtual environment for running ShakeMap. 
 
-To install with developer tools included, run the same install script but with the "-d" switch:
-```
-> bash install.sh -d
-```
-This will install these additional packages:
- - ipython
- - autopep8
- - flake8
- - pyflakes
- - rope
- - yapf
- - sphinx
- - sphinx-argparse
-
-
-**If you do not have conda already installed and experience a significant delay during the "solving environment" step:** Install [mamba](https://mamba.readthedocs.io/en/latest/getting_started.html#for-new-users), a conda alternative, prior to shakemap install.
-
 If the script finishes without errors, then the final two lines of output will be
 ``` 
 Successfully installed shakemap
 Type 'conda activate shakemap' to use this new virtual environment.
 ```
 
-On some OSs, you may see errors that end with something like:
