+## Acknowledgments
+
+Much of the V-Sport Project is derived from [Vulkan-Tutorial-Java][vtj]
+by Cristian Herrera, which was in turn ported from
+[Alexander Overvoorde's Vulkan tutorial][vt].
+I am deeply grateful for all the work that went into these invaluable tutorials.
+
+This project has made use of the following libraries and software tools:
+
+  + the [Firefox] web browser
+  + the [Git] revision-control system and GitK commit viewer
+  + the [GitKraken] client
+  + the [GLFW] library
+  + the [Gradle] build tool
+  + the [Java] compiler, standard doclet, and runtime environment
+  + the [Java OpenGL Math Library][joml]
+  + [the Lightweight Java Gaming Library][lwjgl]
+  + the [Markdown] document-conversion tool
+  + the [NetBeans] integrated development environment
+  + Microsoft Windows
+  + the [Vulkan] API
+
+I am grateful to [GitHub] and [Imgur]
+for providing free hosting for this project
+and many other open-source projects.
+
+I'm also grateful to my dear Holly, for keeping me sane.
+
+If I've misattributed anything or left anyone out, please let me know, so I can
+correct the situation: sgold@sonic.net
