Download and install Meteor. When Meteor is installed, run the following commands to start the project locally:
git clone git@github.com:danielsvane/molecules.git
cd molecules
meteor
Besides Meteor, this project uses three.js to render the particles, KaTeX to display the equations and Algebrite to do symbolic algebra. Algebrite is a great library, but does rather slow evaluation, so the output from Algebrite is parsed to a string which javascript can evaluate, using nearley.js.
