+# UXID [![Issues][issues_shield]][issues_url] [![MIT License][license_shield]][license_url]
+
+This project contains the specification and reference implementations of a type of unique identifier called a UXID.
+
+UXID stands for **U**ser e**X**perience focused **ID**entifier and is similar to a [ULID][ulid_url], with a strong focus on UX.
+
+## Why UXIDs?
+
+ID generation is a fun topic (for some :) and there are many existing libraries to do so (see [Alternatives]).
+ID generation is a fun topic (for some :) and there are many existing libraries to do so (see [Alternatives](#alternatives)).
+UXIDs build on strong concepts from some of these alternatives and have these primary goals:
+
+  * User experience focused
+  * No coordination, no collisions, no (fixed) cardinality
+  * Sortable by time
+
+### User Experience Focused
+
+Most ID generation libraries focus on creating unique identifiers to work for the system (often distributed) and give little thought to the humans who use them.
+
+Who are these humans you speak of? There are two large groups:
+
+* The customer and tech support heros who need to easily pronounce and hear them over the phone.
+* The engineers investigating a complex issue with multiple objects of different types.
