 ## Building and installing
 
-1.  Check `.bazelrc` to see if the Xcode version used by Tulsi is installed
-    locally. If it isn't, feel free to remove the `--xcode_version` flag or
-    modify it as you wish, but note that Tulsi may not build correctly with
-    different versions of Xcode.
-1.  Run `build_and_run.sh`. This will install Tulsi.app inside ~/Applications.
+Run `build_and_run.sh`. This will install Tulsi.app inside `$HOME/Applications` by default. See below for supported options:
+
+* `-b`: Bazel binary that Tulsi should use to build and install the app (Default is `bazel`)
+* `-d`: The folder where to install the Tulsi app into (Default is `$HOME/Applications`)
+* `-x`: The Xcode version Tulsi should be built for (Default is `11.3.1`)
