 # /ᐠ｡ꞈ｡ᐟ\ MewMew Programming Language
 ### Program in Cats' Language
 
+MewMew is an Esoteric `Just for Fun` programming language. You can use MewMew to program in cats' language.
+
 ## Get Started
 #### Integers
 There's no concept of numbers (eg. 1 2 3 4 100) in MewMew, instead we use `mew`s. 1 `mew` is equal to 1 , therefor `mewmew` = 2 , `mewmewmew` = 3 , `mewmewmewmewmewmewmewmewmewmew` = 10. (You got the Idea right)
 
+#### Operators
+MewMew supports a few types of operators =>
+    * `+` -> Addition
+    * `-` -> Subtraction
+    * `*` -> Multiplication
+    * `/` -> Division
+    * `**` -> Power
+    * `~` -> Absolute Value
+    * `-` -> Unary Minus
+    * `>` -> Greater than
+    * `>=` -> Greater than equal to
+    * `<` -> Less than
+    * `<=` -> Less than equal to
+    * `==` -> Is Equal to
+    * `!=` -> Not Equal to
+    * `&` -> And
+    * `|` -> Or
+    * `%` -> Modulus (Remainder)
+
+#### Identifiers
+MewMew identifiers must start with an `m` and can contain zero or more consecutive `_` and `w`. `e` cannot be used , because the interpreter can confuse it with a mew number.
+
+#### Assignment
+`ID = Expression`
+IDs will follow the rules of identifiers (above mentioned)
+
 #### Print aka. *Meow Say*
 There's no keyword , to print we use the `::` symbol, for example
 `::mewmew + mewmew` outputs `4`
@@ -20,6 +48,21 @@ If statement of mewmew is very similar to ternary expression of C/C++.
 `@TIMES : BODY ;`
 Where `TIMES` can be any mew number , and the `BODY` will be executed `TIMES` times.
 
+#### Scratch Functions
+`#MEWNUMBER` (The '#' can be 1 to 5 consecutive times )
+*   1 `#` calculates square root of the expression
+*   2 `#` returns 2 times the given expression
+*   3 `#` returns 5 times the given expression
+*   4 `#` returns 10 times the given expression
+*   5 `#` returns 100 times the given expression

+#### Comments

+To write a comment , start the sentence with `//`
+
+## NOTEs:
+*  MewMew is an esoteric language , it was never intended to be used for mainstream programming.
+*  MewMew is only tested on Linux device (Ubuntu 18.04 x86_64). Building on Windows or MacOS should not be difficult , Please let me know , if you build it on either Windows or MacOs.
