+## AO bakery for Assetto Corsa
 
-AO bakery for Assetto Corsa, powered by NVIDIA OptiX Prime, supports tracks and cars (and requires **v0.1.25-preview194** version 
-of Custom Shaders Patch to work). 
+This is a CUDA-accelerated ambient occlusion bakery for racing simulator Assetto Corsa with Custom Shaders Patch, supporting tracks and cars. Made possible with NVIDIA OptiX Prime, forked from [this project](https://github.com/nvpro-samples/optix_prime_baking).
 
-To run it on CPU, open `baked_shadow_params.ini` and set `CPU_ONLY = 1`, although at least on my PC with GTX 1060 it runs about 
-100 times faster with hardware acceleration.

-More detailed description and proper documentation are coming soon.
+## Features
+
+- Tracks:
+  - Both KN5 and INI files are supported as inputs;
+  - Special trees baking (without self-occlusion, with normals facing up);
+  - Special grass baking (without any shadows from grass, with normals facing up);
+  - Optional trees transparency factor;
+  - Skips dynamic objects to shadow them dynamically later on;
+  - Baking of extra samples along the track for occlusion for dynamic objects;
+
+- Cars:
+
+  - Full LODs support, as well as COCKPIT_HR/COCKPIT_LR;
+  - Special processing for seatbelts;
+  - Special processing for rotating objects to keep shadows uniform;
+  - AO splitting for doors, steering wheel and other animations, allowing to transition between AO values realtime ([demo](https://gfycat.com/felinepassionateangwantibo));
+  - Baking shadows for driver;
+  - Baking shadows from driver in an alternative AO set;
+  - Raising ambient brightness to compensate for new AO;
+  - Extra pass for adding a bit of light “bounced” from the ground;
+
+- Alter brightness, opacity and gamma for resulting AO;
+- Adjust AO per-object if necessary;
+- Adjust sampling offsets per-object to get rid of arifacts in complicated cases.
+
+## Tips
+
+- Various options could be changed in `baked_shadow_params.ini`;
+- To run it on CPU, set `CPU_ONLY = 1`, although at least on my PC with GTX 1060 it runs about 
+100 times faster with hardware acceleration (2.5 s vs 4 min for main pass).
