+# raylib parser
+
+This parser scans [`raylib.h`](../src/raylib.h) to get information about `structs`, `enums` and `functions`.
+All data is separated into parts, usually as strings. The following types are used for data:
+
+ - `struct FunctionInfo`
+ - `struct StructInfo`
+ - `struct EnumInfo`
+ 
+Check `raylib_parser.c` for details about those structs.
+
+## Command Line Arguments
+
+The parser can take a few options...
+
+- `--help` Displays help information about the parser
+- `--json` Outputs the header information in JSON format
+
+## Constraints
+
+This parser is specifically designed to work with raylib.h, so, it has some constraints: 
+
+ - Functions are expected as a single line with the following structure:
+```
+   <retType> <name>(<paramType[0]> <paramName[0]>, <paramType[1]> <paramName[1]>);  <desc>
+```
+   Be careful with functions broken into several lines, it breaks the process!
+   
+ - Structures are expected as several lines with the following form:
+```
+   <desc>
+   typedef struct <name> {
+       <fieldType[0]> <fieldName[0]>;  <fieldDesc[0]>
+       <fieldType[1]> <fieldName[1]>;  <fieldDesc[1]>
+       <fieldType[2]> <fieldName[2]>;  <fieldDesc[2]>
+   } <name>;
+```
+ - Enums are expected as several lines with the following form:
+```
+   <desc>
+   typedef enum {
+       <valueName[0]> = <valueInteger[0]>, <valueDesc[0]>
+       <valueName[1]>,
+       <valueName[2]>, <valueDesc[2]>
+       <valueName[3]>  <valueDesc[3]>
+   } <name>;
+```   
+   
+_NOTE: For enums, multiple options are supported:_
+      
+ - If value is not provided, (<valueInteger[i -1]> + 1) is assigned
+ - Value description can be provided or not
+
+## Additional notes
+
+This parser _could_ work with other C header files if mentioned constraints are followed.
+
+This parser **does not require `<string.h>` library**, all data is parsed directly from char buffers.
