+All other dependencies will be vendored if missing as part of Perspective's CMake build, but you can install them yourself and CMake will detect them via the usual mechanisms.

 ### Installation
 
 To install the base package from pip:
 
 `pip install perspective-python`
 
-To Install from source:

-`make install`

 To install the JupyterLab extension:
 
 `jupyter labextension install @finos/perspective-jupyterlab`
 
-or from source:
