+# Pure - A minimal and beautiful theme for oh-my-zsh

+# Based on the custom Zsh-prompt of the same name by Sindre Sorhus. A huge
+# thanks goes out to him for designing the fantastic Pure prompt in the first
+# place! I'd also like to thank Julien Nicoulaud for his "nicoulaj" theme from
+# which I've borrowed both some ideas and some actual code. You can find out
+# more about both of these fantastic two people here:
