+### Proxy Lists
+To use proxy lists, navigate to `api/secret/proxies/` and create the following files:
+- `http.txt`
+- `socks4.txt`

+
+Then, paste your proxies in the following format:
+

+[username:password@]host:port
+```
+Whereas anything inside of `[]` is optional and the host can be an IP address or a hostname. Always specify the port.

+- Order any type of proxy or proxies
+- In the *Product Info* tab:

+aaaaaaaaaaaaa:bbbbbbbbbb@1.2.3.4:5555

+In the proxy credential files, can use comments just like in Python.

+**Important:** to activate the proxy lists, you need to change the `USE_PROXY_LIST` environment variable to `True`!

+### ~~`ACTUAL_IPS` (optional)~~ (deprecated, might come back in the future)
 This is a security measure to make sure a proxy, VPN, Tor or any other IP hiding service is used by the host when accessing "Closed"AI's API.
 It is a space separated list of IP addresses that are allowed to access the API.
 You can also just add the *beginning* of an API address, like `12.123.` (without an asterisk!) to allow all IPs starting with `12.123.`.
 > To disable the warning if you don't have this feature enabled, set `ACTUAL_IPS` to `None`.
