 ## Demo
 For a practical example, look at the example XML file under `resources`. The XML file describes the format of a WASM object file:<br/>

+## Memory Leaks
+Code generated by faultreiber should not leak any memory if everything went according to plan during code-gen. If that's not the case let me knkow.<br/>
+
+## How to Use
+A function named `read_aggr_{name}` will be generated that takes an `int _fd` file descriptor for the file that it will read.`{name}` is what you pass to faultreiber with the `--name` option.<br/>
+The return type will be a C structure with type `{name}_lib_ret_t`. The struct is defined as:<br/>
+```C
+typedef struct {
+  name_obj_t obj;
+  void** void_train;
+  uint64_t* current_void_size;
+  uint64_t* current_void_count;
+}name_lib_ret_t
+```
+`{name}_obj_t` is a C structure defined in `aggregate.h` that holds all the read modules.<br/>
+A function named `release_all_{name}` will be generated in `aggregate.c` that releases almost all the memory.<br/>
+The proper order of realeasing the memory in the client code will be like below assuming the return value of `read_aggr_{name}` is stored in `lib_ret` and `--name` was passed a value of `wasm`:<br/>
+```C
+release_all_wasm(lib_ret->void_train, lib_ret->current_void_count);
+free(lib_ret->obj);
+free(lib_ret);
+```
