+CUDA Path Tracer
+================
+
+**University of Pennsylvania, CIS 565: GPU Programming and Architecture, Project 3**
+
+* (TODO) YOUR NAME HERE
+* Tested on: (TODO) Windows 22, i7-2222 @ 2.22GHz 22GB, GTX 222 222MB (Moore 2222 Lab)
+
+### (TODO: Your README)
+
+Include analysis, etc. (Remember, this is public, so don't put
+anything here that you don't want to share with the world.)
+
+Instructions (delete me)
+========================
+
+This is due **INSTRUCTOR TODO** evening at midnight.
+
+**Summary:**
+
+
+### Controls
+
+* W/A/S/D and R/F fly. Arrow keys rotate.
+
+### INSTRUCTOR TODO
+
+* Look for important parts of the code in the following files. You can search
+  for `CHECKITOUT` in the code.
+  * `src/interactions.h`: ray scattering functions
+  * `src/intersections.h`: ray intersection functions
+  * `src/pathtrace.cu`: path tracing kernels, device functions, and calling code
+  * `src/main.cpp`: optionally, allows you to save HDR image files
+
+```
+    thrust::default_random_engine rng(hash(index));
+    thrust::uniform_real_distribution<float> u01(0, 1);
+    float result = u01(rng);
+```
+
+There is a convenience function for generating a random engine using a
+combination of index, iteration, and depth as the seed:
+
+```
+  thrust::default_random_engine rng = random_engine(time, iter, depth);
+```
+
+
+## Submit
+
+If you have modified any of the `CMakeLists.txt` files at all (aside from the
+list of `SOURCE_FILES`), you must test that your project can build in Moore
+100B/C. Beware of any build issues discussed on the Google Group.
+
+1. Open a GitHub pull request so that we can see that you have finished.
+   The title should be "Submission: YOUR NAME".
+2. Send an email to the TA (gmail: kainino1+cis565@) with:
+   * **Subject**: in the form of `[CIS565] Project 2: PENNKEY`
+   * Direct link to your pull request on GitHub
+   * Estimate the amount of time you spent on the project.
+   * If there were any outstanding problems, or if you did any extra work,
+     briefly explain for grading purposes.
+   * Feedback on the project itself, if any.
