# Directives

**JM-'**s directives are statements for the program itself and not instructions for the preprocessor like in **C**/**C++**

* `#incd` Is used to include libraries in your project ([read more about libraries](/jmdash-docs/jmbasics/syntax101/calling-functions/other-libraries.md))
* `#def` Is used to define functions in your project\
  -> You can also append the `_macro()` option to `#def` to create a **macro** instead of a **definition**.\
  -> The difference between **macros** and **definitions** is that;\
      **Macros** work like **Python**'s define statement and just run a portion of code.\
      On the other hand **Definitions** in **JM-** are used to create entirely new functions\
