+# *COS 2:* Lua Program
+
+## Quick information
+
+| Information |                           |
+| ----------- | ------------------------- |
+| Type        | Lua Program               |
+| MIME        | `lua/program`             |
+| Extensions  | `.prg`, `.lua` *See '.lua extension'*|
+
+## Technical details
+
+*This format is based upon [plain text](/File%20Formats/Documents/Plain%20Text.md) and as such technical details that apply to plain text also apply to this format.*
+
+A Lua program file *must* contain valid Lua code which will immediately execute code upon being run, rather than simply returning data or loading functions. There is no requirement for a 'program' to have any user interaction or utilise the screen, but to simply *run* code rather than *load* it.
+
+### Note: Usage of `.lua` extension
+
+A file with the `.lua` extension by default should be assumed to be a Lua program, not any other type of Lua file. However, you should never use the `.lua` extension when creating new files unless the user manually specifies it.
