 ## Run Instructions
 
-- Use `stack run <file>` to run the program (for example, `stack run example/1`).
+- Use `stack run <file>` to run the program (for example, `stack run example/1.fs`).
 - The LLVM will be generated as `a.out.ll`, and the executable will be generated as `a.out`.
 
+## Language
+
+It is planned to be similar to Forth, unless it turns out that Forth does not have the features I am looking for.
+
+Currently, it supports positive integers, `+`, `-`, `*`, `/`, and `.` (pops from stack and outputs to console).
+
+The supported syntax for this compiler aims to be compatible with Gforth.
+
 ## To edit
 
 I recommend using VSCodium, which is preconfigured to have syntax highlighting and (currently broken) debugging features and will automatically suggest the Haskell extensions to install.
