 ## Install lean
 
 You can use the `install` ninja/make target to install Lean into, by default,
-`C:\\User Programs (x86)\\LEAN`. To change this, add `-DCMAKE_INSTALL_PREFIX=path/you/want`
-to your cmake invocation.
+`./build/release/stage1/msys64/lean/`. To change this, add `-DCMAKE_INSTALL_PREFIX=path/you/want`
+to your initial cmake invocation.
+
+## Running
+
+You can run `lean --version` to see if your binaries work.
+
+If you want a version that can run independently of your MSYS install
+then you need to copy the following dependent DLL's from where ever
+they are installed in your MSYS setup:
+
+- libgcc_s_seh-1.dll
+- libstdc++-6.dll
+- libgmp-10.dll
+- libwinpthread-1.dll
+
+The following linux command will do that:
+
+```bash
+cp $(ldd lean.exe | cut -f3 -d' ' | grep mingw) .
