 ==== About Dependencies Management
 
 A crate can depend on other libraries from crates.io or git repositories, listed
-in its Cargo.toml file. Before starting a build, Cargo usually downloads
-automatically them. This step can also be performed independently, via the
-+cargo fetch+ command.
+in its Cargo.toml file. Before starting a build, the +cargo vendor+ command
+will be run and will take care of downloading those dependencies.
 
-Cargo maintains a local cache of the registry index and of git checkouts of the
-crates, whose location is given by +$CARGO_HOME+. As seen in the package
-Makefile example at line 15, this environment variable is set to
-+$(HOST_DIR)/share/cargo+.
-
-This dependency download mechanism is not convenient when performing an offline
-build, as Cargo will fail to fetch the dependencies. In that case, it is advised
-to generate a tarball of the dependencies using the +cargo vendor+ and add it to
-+FOO_EXTRA_DOWNLOADS+.
+The final source tarball will contain all the required dependencies, effectively
+permitting us to do an offline build.
