+# Hash Array Mapped Trie
+
+A barebones implementation of [this paper](https://infoscience.epfl.ch/record/64398) by Phil Bagwell. 
+
+### Usage
+
+As an example: 
+```zig
+const std = @import("std");
+const expectEqual = std.testing.expectEqual;
+const HashArrayMappedTrie = @import("hamt").HashArrayMappedTrie;
+
+const StringTrie = HashArrayMappedTrie([]const u8, void, StringContext);
+
+const StringContext = struct {
+    // Note: This definition is *required*
+    // TODO: I could just grab the @typeInfo(HashFn).Fn.return_type right?
+    pub const Digest = u64;
+
+    pub inline fn hash(key: []const u8) Digest {
+        return std.hash.Wyhash.hash(0, key);
+    }
+
+    pub inline fn eql(left: []const u8, right: []const u8) bool {
+        return std.mem.eql(u8, left, right);
+    }
+};
+
+test {
+    const Pair = StringTrie.Pair;
+    const allocator = std.testing.allocator;
+
+    var trie = StringTrie.init();
+    defer trie.deinit(allocator);
+
+    try trie.insert(allocator, "hello", {});
+
+    try expectEqual(@as(?Pair, .{ .key = "hello", .value = {} }), trie.search("hello"));
+    try expectEqual(@as(?Pair, null), trie.search("world"));
+}
+```
+
+### Building 
+
+Build in release mode with `zig build -Doptimzie=ReleaseSafe`;
