+Cheesemap
+====
+
+Cheesemap is a swiss-table like HashMap implementation in C. It's designed to be fast but also easy to understand and improve.
+The HashMap might be a little memory efficient especially right after resizes and doesn't yet provide a shrink method. The HashMap
+is not yet production tested but fully working.
+
+* Example
+```
+#include "cheesemap.h"
+#include <stdint.h>
+#include <string.h>
+#include <stddef.h>
+
+struct user_info {
+	const char* country;
+	int age;
+	int zip;	
+};
+
+uint64_t hash(const uint8_t* key) {
+	const char* name = (const char*)key;
+	uint64_t count;
+	while(*name) {
+		count++;
+		name++;
+	}
+
+	return count;
+}
+
+bool compare(const uint8_t* key1, const uint8_t* key2) {
+	const char* name1 = (const char*)key1;
+	const char* name2 = (const char*)key2;
+	return strcmp(name1, name2);
+}
+
+int main() {
+	struct cheesemap map;
+	cm_new(&map, sizeof(const char*), _Alignof(const char*), sizeof(struct user_info), _Alignof(struct user_info), NULL
+}	
+```
