+First get Nim from github:

 ```
-# step 1:
 git clone https://github.com/nim-lang/Nim.git
 cd Nim
-
-# step 2 (posix) clones `csources.git`, bootstraps Nim compiler and compiles tools
-sh build_all.sh
-
-# step 2 (windows)
-git clone --depth 1 https://github.com/nim-lang/csources.git
-
-cd csources
-# requires `gcc` in your PATH, see also https://nim-lang.org/install_windows.html
-build.bat # x86 Windows
-build64.bat # x86_64 Windows
-cd ..
-
-bin\nim c koch
-koch boot -d:release
-koch tools # Compile Nimble and other tools
-# end of step 2 (windows)
 ```
 
+Next run the appropriate build shell script for your platform:
+
+* `build_all.sh` (Linux, Mac)
+* `build_all.bat` (Windows)
+
+
 Finally, once you have finished the build steps (on Windows, Mac or Linux) you
 should add the ``bin`` directory to your PATH.
