+  The "cargo wix" subcommand provides a variety of predefined variables available
+  for customization of this template. The values for each variable are set at
+  installer creation time. The following variables are available:
+
+  TargetTriple      = The rustc target triple name.
+  TargetEnv         = The rustc target environment. This is typically either
+                      "msvc" or "gnu" depending on the toolchain downloaded and
+                      installed.
+  TargetVendor      = The rustc target vendor. This is typically "pc", but Rust
+                      does support other vendors, like "uwp".
+  CargoTargetBinDir = The complete path to the directory containing the
+                      binaries (exes) to include. The default would be
+                      "target\release\". If an explicit rustc target triple is
+                      used, i.e. cross-compiling, then the default path would
+                      be "target\<CARGO_TARGET>\<CARGO_PROFILE>",
+                      where "<CARGO_TARGET>" is replaced with the "CargoTarget"
+                      variable value and "<CARGO_PROFILE>" is replaced with the
+                      value from the "CargoProfile" variable. This can also
+                      be overridden manually with the "target-bin-dir" flag.
+  CargoTargetDir    = The path to the directory for the build artifacts, i.e.
+                      "target".
+  CargoProfile      = The cargo profile used to build the binaries
+                      (usually "debug" or "release").
+  Version           = The version for the installer. The default is the
+                      "Major.Minor.Fix" semantic versioning number of the Rust
+                      package.

+
+                      1. Uncomment the `Component` tag and its contents.
+                      2. Change the value for the `Source` attribute in the `File` tag to a path
+                         to the file that should be included as the license sidecar file. The path
+                         can, and probably should be, relative to this file.
+                      3. Change the value for the `Name` attribute in the `File` tag to the
+                         desired name for the file when it is installed alongside the `bin` folder
+                         in the installation directory. This can be omitted if the desired name is
+                         the same as the file name.
+                      4. Uncomment the `ComponentRef` tag with the Id attribute value of "License"
+                         further down in this file.
