 ```
 git clone git@github.com:JohnSully/KeyDB.git
-docker run -it --rm `pwd`/KeyDB:/build -w /build devopsdood/keydb-builder make
+docker run -it --rm -v `pwd`/KeyDB:/build -w /build devopsdood/keydb-builder make
 ```
 
 Then you have fresh binaries built, you can also pass any other options to the make command above after the word make. E.g.
 
-```docker run -it --rm `pwd`/KeyDB:/build -w /build devopsdood/keydb-builder make MAllOC=memkind```
+```docker run -it --rm -v `pwd`/KeyDB:/build -w /build devopsdood/keydb-builder make MAllOC=memkind```
 
 The above commands will build you binaries in the src directory. Standard `make install` without Docker command will work after if you wish to install
