+## Build cache
+
+Cargo shares build artifacts among all the packages of a single workspaces.
+Today, Cargo does not share build results across different workspaces, but
+a similar result can be achieved by using a third party tool, [sccache].
+
+To setup `sccache`, install it with `cargo install sccache` and set
+`RUSTC_WRAPPER` environmental variable to `sccache` before invoking Cargo.
+If you use bash, it makes sense to add `export RUSTC_WRAPPER=sccache` to
+`.bashrc`. Refer to sccache documentation for more details.
