+Ergo (formerly known as Oragono) is a modern IRC server written in Go. Its core design principles are:
 
 * Being simple to set up and use
 * Combining the features of an ircd, a services framework, and a bouncer (integrated account management, history storage, and bouncer functionality)
 * Bleeding-edge [IRCv3 support](https://ircv3.net/software/servers.html), suitable for use as an IRCv3 reference implementation
 * Highly customizable via a rehashable (i.e., reloadable at runtime) YAML config
 
-Oragono is a fork of the [Ergonomadic](https://github.com/jlatt/ergonomadic) IRC daemon <3

 ## Quick start guide
 
-Download the latest release from this page: https://github.com/oragono/oragono/releases/latest
+Download the latest release from this page: https://github.com/ergochat/ergo/releases/latest
 
 Extract it into a folder, then run the following commands:
 
 ```sh
 cp default.yaml ircd.yaml
 vim ircd.yaml   # modify the config file to your liking
-oragono mkcerts
-oragono run     # server should be ready to go!
+ergo mkcerts
+ergo run     # server should be ready to go!
 ```
 
-**Note:** See the [productionizing guide in our manual](https://github.com/oragono/oragono/blob/master/docs/MANUAL.md#productionizing-with-systemd) for recommendations on how to run a production network, including obtaining valid TLS certificates.

 ### Platform Packages
 
 
 #### Building
 
-You'll need an [up-to-date distribution of the Go language for your OS and architecture](https://golang.org/dl/). Once you have that, just clone the repository and run `make build`. If everything goes well, you should now have an executable named `oragono` in the base directory of the project.

 ## Configuration
 
 The default config file [`default.yaml`](default.yaml) helps walk you through what each option means and changes.
 
-You can use the `--conf` parameter when launching Oragono to control where it looks for the config file. For instance: `oragono run --conf /path/to/ircd.yaml`. The configuration file also stores where the log, database, certificate, and other files are opened. Normally, all these files use relative paths, but you can change them to be absolute (such as `/var/log/ircd.log`) when running Oragono as a service.

 ### Logs
 
 Passwords (for both `PASS` and oper logins) are stored using bcrypt. To generate encrypted strings for use in the config, use the `genpasswd` subcommand as such:
 
 ```sh
-oragono genpasswd
+ergo genpasswd
 ```
 
 With this, you receive a blob of text which you can plug into your configuration file.
 
 ### Nickname and channel registration
 
-Oragono relies heavily on user accounts to enable its distinctive features (such as allowing multiple clients per nickname). As a user, you can register your current nickname as an account using `/msg NickServ register <password>`. Once you have done so, you should [enable SASL in your clients](https://freenode.net/kb/answer/sasl), ensuring that you will be automatically logged into your account on each connection. This will prevent [problems claiming your registered nickname](https://github.com/oragono/oragono/blob/master/docs/MANUAL.md#nick-equals-account).
