 When it's time for you to test out your install or for another user to install your agent, it's pretty simple. Within Mythic is a `mythic-cli` binary you can use to install agents:
 
 - `sudo ./mythic-cli install github https://github.com/user/repo` to install the main branch
-- `sudo ./mythic-cli install github https://github.com/user/repo branchname` to install a specific branch of that repo
+* `sudo ./mythic-cli install github https://github.com/user/repo -b branchname` to install a specific branch of that repo
 
 Now, you might be wondering _when_ should you or a user do this to properly add your agent to their Mythic instance. There's no wrong answer here, just depends on your preference. The three options are:
 
-- Mythic is already up and going, then you can run the install script and just direct that agent's containers to start (i.e. `sudo ./mythic-cli payload start agentName` and if that agent has its own special C2 containers, you'll need to start them too via `sudo ./mythic-cli c2 start c2profileName`).
-- Mythic is already up and going, but you want to minimize your steps, you can just install the agent and run `sudo ./mythic-cli mythic start`. That script will first _stop_ all of your containers, then start everything back up again. This will also bring in the new agent you just installed.
-- Mythic isn't running, you can install the script and just run `sudo ./mythic-cli mythic start`.
