+## Data Generator
+a simple domain specific language which allows you to generate data fast and easy
+## Usage
+
+Here is an example of how to generate data of a+b problem using data generator
+
+create a new text file named `example.txt`
+
+open the editor and write
+
+```
+{i32} {i32}
+```
+execute using data generator
+
+```bash
+## linux
+./data_generator -f example.txt -c 10
+## replace `./data_generator` to `data_generator.exe` in windows
+```
+
+waiting for some time and it is done,how easy it is!
+
+## Tokens
+
+### single tokens
+
+here a some single tokens which are allow to use in data_generator
+
+```rust
+i16 //short
+i32 //int
+i64 //long long
+i128 //int128_t
+
+/*tokens start with u are all the tokens above but unsigned.So no marks here*/
+u16
+u32
+u64
+u128
+
+char // A UTF-8 charaters
+string //ASCII. range from 20 to 126 (that means no control charaters.Will add some later) (the maxium len are u16::MAX)
+bigint //maxium len are u16::MAX
+```
+
+### multiple tokens
+
+TODO...
+
+
+
+## TODOs
+
+add multiple tokens (allows user to control the random data more fine)
+
+add documentations for the source code
