 General useful scripts (mostly for Linux)
 
 # dns_fetch.py
+---
 This lovely python script allows you to fetch ip address form cloudflare dns records. Useful for remote servers with dynamic ips. You can define the env file "dns_resolv_env.json" as follows:
 ```
 {
-        "auth_key": "key here (required without --auth)",
-        "zone_id": "zone id here (optional)",
-        "default_name": "website name here (optional)"
+        "auth_key": "key here",
+        "zone_id": "zone id here",
+        "default_name": "website name here"
 }
 ```
-The script has many useful featues:
+### Notes
+---
+- The env file itself is optional but the script will require you to pass your auth key with `--auth "key here"`
+- If no zone id is provided the script will fetch and print from ALL zones on your cloudflare account.
+- If default_name is not specified by either file or via `-n "name"`, filtering will be ignored
+### Usage Examples
+---
 - `python3 dns_fetch.py -a -n -i` 
     - Returns only the ip address of the A record corresponding to default_name.
         - This can be used in bash commands: `ssh username@$(python3 dns_fetch.py -a -n -i)`
