+# Command Line Arguments
+
+```
+usage: joshuto [options] [path]
+```
+ - `[path]`: tells joshuto to start in a specific directory
+
+Joshuto supports the following options from the command line:
+
+ - `-v` `--version`: outputs version of joshuto
+
+ - `-h` `--help`: shows help menu
+
+ - `--output-file <output-file>`: tells joshuto to output data to `<output-file>`.
+   - This is usually used so programs can know how to behave after joshuto exits.
+   - For example, cd into joshuto's current directory on quit
