+# How to use
+
+You can just run the executable and you'll be in REPL mode,
+or specify an input file like `-f <file>`, the effect is the same as if you
+had put it there yourself.
+
+When reading from a file, REPL is still enabled by default and can be disabled with `--repl-`
+
+## Options
+
+You can also change some of the behaviours of the interpreter:
+
+```shell
+--cell_limit:limit (for example --cell_limit:10000) - limit the amount of cells that can be used
+--command_strs[+/-] (for example --command_strs+) - use string representation of commands, useful
+                                                    for debugging the compiler with verbose logging
+--default_log_level:level (for example --default_log_level:3) - change the default logging level
+--repl[+/-] (for example --repl-) - enable/disable repl
+```
