# grid-manager(1)

A Tahoe Grid Manager for issuing certificates to storage-servers.

## NAME

grid-manager - A Tahoe Grid Manager for issuing certificates to storage-servers.

## SYNOPSIS

**grid-manager** \[*OPTIONS*\] *COMMAND* \[*ARGS*\]...

Grid Manager configuration can be in a local directory or given via stdin. It contains long-term secret information (a private signing key) and should be kept safe.

## COMMANDS
