 ## Building the CLI
 
-If you are in a full checkout of the TVL depot, you can simply run `mg build`
-in the `cli` directory (or `mg build //tvix/cli` from anywhere in the repo).
-The `mg` command is found in `/tools/magrathea`.
+The CLI can also be built with standard Rust tooling (i.e. `cargo build`),
+as long as you are in a shell with the right dependencies.
+
+ - If you cloned the full monorepo, it can be provided by `mg shell //
+   tvix:shell`.
+ - If you cloned the `tvix` workspace only
+   (`git clone https://code.tvl.fyi/depot.git:workspace=views/tvix.git`),
+   `nix-shell` provides it.
+
+If you're in the TVL monorepo, you can also run `mg build //tvix/cli`
+(or `mg build` from inside that folder) for a more incremental build.
 
+Please follow the depot-wide instructions on how to get `mg` and use the depot
+tooling.

+### Compatibility
 **Important note:** We only use and test Nix builds of our software
 against Nix 2.3. There are a variety of bugs and subtle problems in
 newer Nix versions which we do not have the bandwidth to address,
 builds in newer Nix versions may or may not work.
