# Chainspecs Collections
Source repository: [github.com/paritytech/chainspecs](https://github.com/paritytech/chainspecs)
A chain specification, or "chainspec", is a collection of configuration information that dictates which network a blockchain node will connect to, which entities it will initially communicate with, and what consensus-critical state it must have at genesis.
## Usage
You can download chainspec and save it as `chainspec.json` file, then start the substrate node with the `--chain ./chainspec.json` flag.
> ⚠️ For some nodes, you may save chainspec with a different name [see](https://github.com/PureStake/moonbeam/issues/1104#issuecomment-996787548)
> ⚠️ For production, it is better to use the chainspec provided in the binary (e.g., `--chain kusama`). This repo is designed to contain the latest chainspecs before release (for test purposes).
> ⚠️ All chainspecs are sourced from the default development branch, **not** the last release.
> Source repositories (git submodules) are updated once a week.
