 This will build Boostdep from source using the default "toolset" (a Boost.Build term meaning "compiler") and if successful, place it into the dist/bin subdirectory. The command assumes that b2 (the Boost.Build executable) is somewhere in your path. If you don't have b2, execute:
 
 ```bash
-.\bootstrap
+./bootstrap
 ```
 
 Change your current directory to the Boost root directory and invoke b2 as follows:
 
 ```bash 
-.\b2 -j2 --with-timer --with-program_options 
+./b2 -j2 --with-timer --with-program_options --with-regex
