# Creating indexes

Once the radiance tooling has been used to prepare a car file (or if you have downloaded a car file externally), you can generate indexes from this car file by using the `faithful-cli`:

```
NAME:
   faithful CLI index - Create various kinds of indexes for CAR files.

USAGE:
   faithful CLI index command [command options] [arguments...]

DESCRIPTION:
   Create various kinds of indexes for CAR files.

COMMANDS:
   cid-to-offset  
   slot-to-cid    
   sig-to-cid     
   all            Create all the necessary indexes for a Solana epoch.
   gsfa           
   sig-exists     
   help, h        Shows a list of commands or help for one command

OPTIONS:
   --help, -h  show help
```

### Examples

* `faithful-cli index all <car-file> <output-dir>`: Generate all **required** indexes for a CAR file.
* `faithful-cli index gsfa <epoch-number> <car-file> <output-dir>`: Generate the gsfa index for a CAR file.

NOTES:

* You need to have the CAR file available locally.
* The `cid_to_offset_and_size` index has an older version, which you can specify with `cid_to_offset`instead of `cid_to_offset_and_size`.

### Flags:

* `--tmp-dir=/path/to/tmp/dir`: Where to store temporary files. Defaults to the system temp dir. (optional)
* `--verify`: Verify the indexes after generation. (optional)
* `--network=<network>`: Network to use for the gsfa index. Defaults to `mainnet` (other options: `testnet`, `devnet`). (optional)
