 Two DNS providers are covered:

 * [Cloudflare](https://www.cloudflare.com/) -- This lets you put your vaultwarden instance under a domain you own or control. Note that Cloudflare can be used as just a DNS provider (i.e., without the proxying functionality that Cloudflare is best known for). If you don't currently own a domain, you may be able to get a free one at [Freenom](https://www.freenom.com/).
 
 It's certainly possible to create a similar setup using other combinations of web server, [ACME client](https://letsencrypt.org/docs/client-options/), and DNS provider, but you'll have to work out the differences in details.

 ## Getting certs using the `lego` CLI
 
@@ -120,18 +120,18 @@ In the DuckDNS example above, Caddy used the `lego` library to get certs via DNS
 Here's an example of how to do this:
 
 1. Download a pre-built `lego` binary for your system from https://github.com/go-acme/lego/releases. Extract the contents to some directory, say, `/usr/local/lego`.
-2. From that directory, run `DUCKDNS_TOKEN=<token> ./lego -a --dns duckdns -d my-bwrs.duckdns.org -m me@example.com run`,
+2. From that directory, run `DUCKDNS_TOKEN=<token> ./lego -a --dns duckdns -d my-vw.duckdns.org -m me@example.com run`,
    substituting appropriate values for the token, domain, and email address. This registers you with Let's Encrypt and
    fetches a certificate for your domain.
-3. Set up a weekly cron job to run `DUCKDNS_TOKEN=<token> ./lego --dns duckdns -d my-bwrs.duckdns.org -m me@example.com renew`.
+3. Set up a weekly cron job to run `DUCKDNS_TOKEN=<token> ./lego --dns duckdns -d my-vw.duckdns.org -m me@example.com renew`.
    This renews your certificate as it nears expiration.
 
 (Note: `lego` requests ECC/ECDSA certs by default. If you are using the [[Rocket HTTPS server|Enabling-HTTPS#via-rocket]] built into vaultwarden, you will need to request RSA certs instead. In the `lego` commands above, add the option `--key-type rsa2048`.)
 
 In this example, the generated outputs you need to configure your reverse proxy with are:
 
-* `/usr/local/lego/.lego/certificates/my-bwrs.duckdns.org.crt` (certificate)
-* `/usr/local/lego/.lego/certificates/my-bwrs.duckdns.org.key` (private key)
+* `/usr/local/lego/.lego/certificates/my-vw.duckdns.org.crt` (certificate)
+* `/usr/local/lego/.lego/certificates/my-vw.duckdns.org.key` (private key)
