# Adding a Host to the Network
This document guides an admin through adding a single host to the network. Keep
in mind that the steps described here must be done for _each_ host the user
wishes to add.
## Step 1: Choose Hostname
The user will need to provide you with a name for their host. The name should
conform to the following rules:
* It should only contain lowercase letters, numbers, and hyphens.
* It should begin with a letter.
* It should end with a letter or number.
## Step 2: Choose IP
The admin should choose an IP for the host. The IP you choose for the new host
should be one which is not yet used by any other host and is in a subnet which
was configured when creating the network.
## Step 3: Create a `bootstrap.json` File
To create a `bootstrap.json` file for the new host, the admin should perform the
following command from their own host:
```
isle hosts create \
--hostname <name> \
--ip <ip> \
> bootstrap.json
```
The resulting `bootstrap.json` file should be treated as a secret file and
shared only with the user it was generated for. The `bootstrap.json` file should
not be re-used between hosts.
The user can now proceed with calling `isle network join`, as described in the
[Getting Started][getting-started] document.
