 DIY Script for Dynamic DNS using Cloudflare APIs
 
 ## INIT
 
 You'll need your Cloudflare API Key (in your profile, on cloudflare website)
 
-Copy `.env.sample` to `.env`:
-```bash
-$ cp .env.sample .env
-```
-
-Edit .env and fill with the email you use on Clouflare and your API KEY.
-
-### Get your DNS zone ID: 
-
-```bash
-$ . .env; \
-  curl -X GET "https://api.cloudflare.com/client/v4/zones" \
-    -H "X-Auth-Email: $EMAIL" \
-    -H "X-Auth-Key: $CLOUDFLARE_API_KEY" \
-    -H "Content-Type: application/json" \
-    | python -m json.tool
-```
-
-Find the right DNS zone, and copy the id to the ZONE_ID var in `.env`.
-
-### Get your DNS entry ID:
-
-```bash
-$ . .env; \
-  curl -X GET "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/dns_records" \
-    -H "X-Auth-Email: $EMAIL" \
-    -H "X-Auth-Key: $CLOUDFLARE_API_KEY" \
-    -H "Content-Type: application/json" \
-    | python -m json.tool
+```sh
+DIYDDNS -init
 ```
-
-Find the right DNS entry, and copy the id and the name to DNS_ID and DNS_NAME vars in `.env`.
-
-BAM, you're good to go.
+and provide your cloudflare email and api key when prompted
 
 ## RUN IT LIKE YOU MEAN IT
 
 Now that you're set, you have to make that run: `all hail the mighty cron`
 
 You should be able to use something like that:
 ```
-* * * * * /bin/bash /path/to/DIYDDNS.sh >> /dev/null
-```
-## Want a PTR with that?
-
-If you want to create a PTR record too, just pass a flag to the cron:
-```
-* * * * * /bin/bash /path/to/DIYDDNS.sh --ptr >> /dev/null
+* * * * * DIYDDNS -fqdn sub.domain.tld >> /dev/null
 ```
