+# Run A Lua Statement From The Command Prompt
+
+The `:lua` command is provided by Neovim as a way to execute a Lua _chunk_.
+
+I can use it to, for instance, execute a print statement.
+
+```
+:lua print('Hello, World!')
+```
+
+I could print out something more interesting like the full path of the current
+file using `vim.fn.expand` with `%`.
+
+```
+:lua print(vim.fn.expand('%'))
+```
+
+Or as the helpfiles point out, I can see the value of some expression by
+including a preceeding `=`.
+
+```
+:lua =jit.version
+```
+
+See `:h :lua` for more details.
