 ## Usage

+**Warning**: This version ZLUDA is under heavy development (more [here](https://vosen.github.io/ZLUDA/blog/zludas-third-life/)) and right now only supports Geekbench. ZLUDA probably will not work with your application just yet.
 
 ### Windows
-You should have the most recent ROCm  installed.\
-Run your application like this:
-```
-<ZLUDA_DIRECTORY>\zluda_with.exe -- <APPLICATION> <APPLICATIONS_ARGUMENTS>

+You should have recent AMD GPU driver ("AMD Software: Adrenalin Edition") installed.\
+To run your application you should etiher:
+* (Recommended approach) Copy ZLUDA-provided `nvcuda.dll` and `nvml.dll` into a path which your application uses to load CUDA. Paths vary application to application, but usually it's the directory where the .exe file is located
+* Use ZLUDA launcher like below. ZLUDA launcher is known to be buggy and unfinished

-_Note_: This repo has submodules. Make sure to recurse submodules when cloning this repo, e.g.: `git clone --recursive https://github.com/vosen/ZLUDA.git`
+### Dependencies
 
- You should have a relatively recent version of Rust installed, then you just do:
+* Git
+* CMake
+* Python 3
+* Rust compiler (recent version)
+* C++ compiler
+* (Optional, but recommended) [Ninja build system](https://ninja-build.org/)
+
+### Build steps
+
+* Git clone the repo (make sure to use `--recursive` option to fetch submodules):  
+`git clone --recursive https://github.com/vosen/ZLUDA.git`  
+* Enter freshly cloned `ZLUDA` directory and build with cargo (this takes a while):  
+`cargo build --release`

 ## Contributing
 
-If you want to develop ZLUDA itself, read [CONTRIBUTING.md](CONTRIBUTING.md), it contains instructions how to set up dependencies and run tests
+ZLUDA project has a commercial backing and _does not_ accept donations.
+ZLUDA project accepts pull requests and other non-monetary contributions.

+If you want to contribute a code fix or documentation update feel free to open a Pull Request.
+
+### Getting started
+
+There's no architecture document (yet). Two most important crates in ZLUDA are `ptx` (PTX compiler) and `zluda` (AMD GPU runtime). A good starting point to tinkering the project is to run one of the `ptx` unit tests under a debugger and understand what it is doing. `cargo test -p ptx -- ::add_hip` is a simple test that adds two numbers.

+Github issues tagged with ["help wanted"](https://github.com/vosen/ZLUDA/issues?q=is%3Aissue+is%3Aopen+label%3A%22help+wanted%22) are  tasks that are self-containted. Their level of difficulty varies, they are not always great starting points, but they have a relatively clear definition of "done".
