 ### Windows
 
 Ensure git is installed on your system. Git can be obtained from https://gitforwindows.org/, as well as other places. If you use the gitforwindows.org distribution, install the Git Bash Shell also as it will aid in debugging the scripts if necessary. Then open a command prompt and run:
 
     cd %LOCALAPPDATA%\darktable
-    git clone https://github.com/darktable.org/lua-scripts.git lua
+    git clone https://github.com/darktable-org/lua-scripts.git lua
 
 If you don't have %LOCALAPPDATA%\darktable you have to start dartable at least once, because the directory is created at the first start of darktable.
