# Install Hermes App on Ignite

Ignite apps add aditional functionality to Ignite's already robust capabilites. Apps allow for testing and deployment of new features, prior to being included in a major release.

With that being said, here is how to add the Hermes App, which allows for the IBC connection between Cosmos SDK based blockchains.

To get started we assume you already have Ignite Install on yoru system. For this tutorial, we are using the latest version of Ignite.

`curl https://get.ignite.com/cli! | bash`

If done correctly, you should see this:


Note Ignite has been installed in our /usr/local/bin/ folder.

Now let's check and see of we what sub-commands are available for "ignite relayer"

We can view them with the following command:

`ignite relayer --help`


As you can see from the picture, we can see there is no 'hermes' listed in the "Available Commands" in 'configure' & 'connect'. Let's change that.

We haev two options here. 1) We can install hermes so it only is available on our current installation. To do that we would cd into our project folder and install there with the 'ignite app install github.com/ignite/apps/hermes' command, but lets install it globally.

Next we can install the hermes app with one simple command:

`ignite app install -g github.com/ignite/apps/hermes`

Note the "-g" flag. This is to install the hermes globally on our Ingite installations, we can install locally to only be used on a specific chain we develope by removing the "-g" flag and running the command in our app's main directory. For example:

ignite scaffold chain blog
cd blog
ignite app install -g github.com/ignite/apps/hermes

If done correctly we should see this:


Perfect, now lets see our "ignite relayer" to see if the "hermes" app has been added. To do that, let's try the same command we used earlier:

`ignite relayer --help`


Great, now let's see what it takes to use Hermes.

`ignite relayer hermes --help `


In our next tutorial we will show you how simple it is to connect two seperate blockchains.
