Installing Pluto

Next we will install Pluto. Remember Pluto is a Julia Package. This means that we install it and run it from inside Julia.

  1. Run Julia the way you were told at the end of the installation instructions above (it varies according to te OS you have). You should bee seeing a window like this:

    By now, you should be comfortable with the fact that Julia has a weird old-school interface. That’s why we use a fancy IDE like Pluto!
  2. With Julia running, type the character ], usually by using the keyboard combination AltGr+9 or Ctrl+Alt+9. The previous window should become like this
  3. Then type: add Pluto ↩ Enter
  4. When the Pluto installation is completed, press ⟵ Backscape to leave the pkg> mode and go back to the julia> mode.

🎉 Well done! By now, Pluto should be correctly installed in your PC. To start Pluto, in the Julia window run:
import Pluto; Pluto.run() ↩ Enter
Notice the space between import and Pluto, the dot between Pluto and run(), and the semicolon ; separating both expressions. All these details are critical!

Pluto will run in a window of your default Browser (we recommend Google Chrome or Firefox).
