# How to do runtime upgrade 1. Compile manta project. ```shell git clone https://github.com/Manta-Network/Manta.git cd Manta cargo build --release ``` 2. Run manta node. ```shell ./target/release/manta --dev --tmp ``` 3. Go to manta runtime crate, search the field `spec_version`(100), and increase it by 1. Just like this, ```rust ... spec_version: 101, ... ``` 4. Now, compile the whole project again. It should go smoothly. When it’s done, find the file `target/release/wbuild/manta-runtime/manta_runtime.compact.wasm`. 5.
