 [![Open in Gitpod](https://gitpod.io/button/open-in-gitpod.svg)](https://gitpod.io/#https://github.com/Minres/TGC-VP)
 
-## Quick start
+## Build instructions for Linux
 
-* you need to have a C++14 capable compiler, make, python, and cmake installed
+You need to have a C++17 capable compiler, make or Ninja, Python 3, and CMake installed.
 
-* install conan.io (see also http://docs.conan.io/en/latest/installation.html):
+To install conan.io version 2.0 and above (see also http://docs.conan.io/en/latest/installation.html) execute the following:
   
-  ```
+```
-
+python3 -m venv .venv
-  pip3 install --user conan
+. .venv/bin/activate
-
+pip3 install conan
-  ```
+conan profile new default --detect
-  
-  It is advised to use conan version 1.36 or newer. In case of an older version please run
-  
-  ```sh
-
-  pip3 install --user --upgrade conan
-
-  ``` 
-  
-  Installing conan for the first time you need to create a profile:
-  
-  ```
-  
-  conan profile create default --detect
-  
-  ```
-  
-* checkout source from git
-
-  ```sh
-
-  git clone --recursive -b develop https://github.com/Minres/TGC-VP.git 
-
-  ``` 
-
-* start an out-of-source build:
-  
-  ```
-
-  cd TGC-VP
-  mkdir build
-  cd build
-  cmake ..
-  make -j tgc-vp
-
-  ```
-  
-* run the VP with pre-built firmware
-
-  ```
-
-  ctest
-
-  ```
-
-  or
-
-  ```
-
-  src/tgc-vp -f ../fw/hello-world/prebuild/hello.elf 
-
-  ```
-  
-To rebuild the firmware you need to install a RISC-V toolchain like https://github.com/riscv/riscv-tools.
-
-# Windows/Visual Studio build
-
-TGC-VP supports VS2019/MSVC 16 and has been tested only with this version
-
-## Prerequisites
-
-You need to have to following installed:
-
-* Visual Studio 2019 (community edition is sufficient) with C/C++ support
-* Python 3.6 or newer
-* SystemC 2.3.3 and SystemC-CCI 1.0.0. Both should be installed into the same location and the 
-  environment variable SYSTEMC_HOME should point to it
-* Conan (https://conan.io/) version 1.36 or newer. If python is installed this can be installed using pip
-  (see above in [Quick start](#quick-start))
-  
-## build step
-
-Create a project at the location of the git workarea. This can be done 
-
 ```
 
-devenv <path to checkout>
+Building the VP is as simple as:
 
+```
+cmake -S . -B build/Release --preset Release && cmake --build build/Release -j24
 ```
 
-The build steps are as described in the VS documentation for CMake based projects.
+Building a debug version is analogous:
-  
+
+```
+cmake -S . -B build/Debug --preset Debug && cmake --build build/Debug -j24
+```
+
+To build some firmware you need to install a RISC-V toolchain like https://github.com/riscv/riscv-tools.
