 ## LOCAL INSTALL ###
 
 If using a local install instead of docker:
 
-* Clone the renderer and its submodules: `git clone --recursive https://github.com/drdrew42/renderer`
+* Clone the renderer and its submodules: `git clone --recursive https://github.com/openwebwork/renderer`
 * Enter the project directory: `cd renderer`
 * Install perl dependencies listed in Dockerfile (CPANMinus recommended)
 * clone webwork-open-problem-library into the provided stub ./webwork-open-problem-library
   - `git clone https://github.com/openwebwork/webwork-open-problem-library ./webwork-open-problem-library`
 * copy `render_app.conf.dist` to `render_app.conf` and make any desired modifications
 * install other dependencies
-  - `cd lib/WeBWorK/htdocs`
+  - `npm install`
+  - `cd lib/PG/htdocs`
   - `npm install`
 * start the app with `morbo ./script/render_app` or `morbo -l http://localhost:3000 ./script/render_app` if changing root url
 * access on `localhost:3000` by default or otherwise specified root url
