+As we have multiple projects we use a workspace to manage them (it's way simpler and leads to less issues). In order
+to vendor all the dependencies we need to store both the registry and the packages themselves.
+
+Note that this includes the exact `std` dependencies for the rustc version used in CI (currently nightly-2024-12-01),
+so you need to install `rustup component add rust-src` for the specific version.
+
+* First step: (Re)-generate the Cargo.lock file (run under `workspace/`).
+
+```bash
+cargo generate-lockfile
+```
+
+* Generate the local registry:
+
+Note that we use both commands to vendor both registry and crates. No idea why both are necessary.
+
+  * First we need to install the tool if you don't already have it:
+```bash
+cargo install --version 0.2.7 cargo-local-registry
+```
+
+  * Now add the local packages:
+
+```bash
+export CH_TOP_DIR=$(git rev-parse --show-toplevel)
+export RUSTC_ROOT=$(rustc --print=sysroot)
+# Currently delta-lake is built outside the workspace (TODO)
+export DELTA_LAKE_DIR="$CH_TOP_DIR"/contrib/delta-kernel-rs
+
+# Clean the vendor repo
+rm -rf "$CH_TOP_DIR"/contrib/rust_vendor/*
+
+cd "$CH_TOP_DIR"/rust/workspace
+cargo local-registry --git --sync Cargo.lock "$CH_TOP_DIR"/contrib/rust_vendor
+
+# Now handle delta-lake
+cd "$DELTA_LAKE_DIR"
+cargo local-registry --no-delete --git --sync "$DELTA_LAKE_DIR/Cargo.lock" "$CH_TOP_DIR"/contrib/rust_vendor

+```
+
+The `rustc --print=sysroot` part includes `std` dependencies, required to build with sanitizer flags. It must be kept
+in sync with the rustc version used in CI.
