+Dear ImGui is a bloat-free graphical user interface library for C++.
+It outputs optimized vertex buffers that you can render anytime in
+your 3D-pipeline enabled application. It is fast, portable, renderer
+agnostic and self-contained (no external dependencies).
+
+Dear ImGui is designed to enable fast iterations and to empower
+programmers to create content creation tools and visualization / debug
+tools (as opposed to UI for the average end-user). It favors
+simplicity and productivity toward this goal, and lacks certain
+features normally found in more high-level libraries.
+
+Dear ImGui is particularly suited to integration in games engine (for
+tooling), real-time 3D applications, fullscreen applications, embedded
+applications, or any applications on consoles platforms where
+operating system features are non-standard.
+
+  * Minimize state synchronization.
+  * Minimize state storage on user side.
+  * Minimize setup and maintenance.
+  * Easy to use to create code-driven and data-driven tools.
+  * Easy to use to create ad hoc short-lived tools and long-lived,
+    more elaborate tools.
+  * Easy to hack and improve.
+  * Portable, minimize dependencies, run on target (consoles, phones,
+    etc.).
+  * Efficient runtime and memory consumption.
+  * Battle-tested, used by many major actors in the game industry.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
