+** Configure Babel Languages
+To execute or export code in ~org-mode~ code blocks, you’ll need to set up ~org-babel-load-languages~ for each language you’d like to use. [[https://orgmode.org/worg/org-contrib/babel/languages.html][This page]] documents all of the languages that you can use with ~org-babel~.

+#+end_src
+
+** Structure Templates
+With just a few keystrokes, it is possible to insert empty [[https://orgmode.org/manual/Structure-Templates.html][structural blocks]], such as ~#+BEGIN_SRC~ … ~#+END_SRC~, or to wrap existing text in such a block.
