This section will walk you through installing cargo-concordium.

To build and test smart contracts on the Concordium blockchain, you'll need the cargo-concordium tool. It serves as a specialized compiler and developer environment for Concordium contracts.

Follow the steps outlined below:

Step 1: Install cargo-concordium

To install cargo-concordium, run the following command in your terminal:

cargo install --locked cargo-concordium

The reason cargo-concordium might already be installed is that adding the "wasm32-unknown-unknown" target with "rustup target add wasm32-unknown-unknown" also installs cargo-concordium for WASM development.

If you need to install a specific version of cargo-concordium, you can do so by using the following command format:

cargo install --locked --force cargo-concordium=your-desired-version

Exercise caution when using this command, as it may overwrite existing versions and settings, potentially causing compatibility issues.
