 ## to Build From The Source (primarily for developers)
 
 This is a monorepo with multiple binaries and the workflow is typical for Rust projects:
 
-- `cargo run --release --bin subspace-node -- --dev --tmp` to run [a node](/crates/subspace-node)
-- `cargo run --release --bin subspace-farmer -- farm` to [start farming](/crates/subspace-farmer)
+- `cargo run --release --bin subspace-node --dev --tmp` to run [a node](/crates/subspace-node)
+- `cargo run --release --bin subspace-farmer farm` to [start farming](/crates/subspace-farmer)
 
 NOTE 1: You need to have `nightly` version of Rust toolchain with `wasm32-unknown-unknown` target available or else you'll get a compilation error.
 NOTE 2: Following the commands above, you will be farming in an offline setting (by yourself).
 NOTE 3: To farm in online setting, you can modify the command accordingly.
