-## How many people can use 1 link
 
-By default, 1 link can be used by any number of people.  
+## How many people can use one link
-You can limit the number of IPs using the proxy.
+
+By default, an unlimited number of people can use a single link.  
+However, you can limit the number of unique IP addresses for each user:
 ```toml
 [access.user_max_unique_ips]
 hello = 1
 ```
-This parameter limits how many unique IPs can use 1 link simultaneously. If one user disconnects, a second user can connect. Also, multiple users can sit behind the same IP.
+This parameter sets the maximum number of unique IP addresses from which a single link can be used simultaneously. If the first user disconnects, a second one can connect. At the same time, multiple users can connect from a single IP address simultaneously (for example, devices on the same Wi-Fi network).
 
 ## How to create multiple different links

+1. Generate the required number of secrets using the command: `openssl rand -hex 16`.
-2. Open the config `nano /etc/telemt.toml`

 user2 = "00000000000000000000000000000002"
 user3 = "00000000000000000000000000000003"
 ```
-4. Save the config. Ctrl+S -> Ctrl+X. You don't need to restart telemt.
+4. Save the configuration (Ctrl+S -> Ctrl+X). There is no need to restart the telemt service.
-5. Get the links via

 ```
 
-## "Unknown TLS SNI" Error
+## "Unknown TLS SNI" error
-You probably updated tls_domain, but users are still connecting via old links with the previous domain.
+Usually, this error occurs if you have changed the `tls_domain` parameter, but users continue to connect using old links with the previous domain.
+
+If you need to allow connections with any domains (ignoring SNI mismatches), add the following parameters:
+```toml
+[censorship]
+unknown_sni_action = "mask"
+```
 
 ## How to view metrics
 
-1. Open the config `nano /etc/telemt/telemt.toml`
+1. Open the configuration file: `nano /etc/telemt/telemt.toml`.
-2. Add the following parameters
+2. Add the following parameters:
 ```toml
 [server]
 metrics_port = 9090
 metrics_whitelist = ["127.0.0.1/32", "::1/128", "0.0.0.0/0"]
 ```
-3. Save the config. Ctrl+S -> Ctrl+X.
+3. Save the changes (Ctrl+S -> Ctrl+X).
-4. Metrics are available at SERVER_IP:9090/metrics.
+4. After that, metrics will be available at: `SERVER_IP:9090/metrics`. 
 > [!WARNING]
-> "0.0.0.0/0" in metrics_whitelist opens access from any IP. Replace with your own IP. For example "1.2.3.4"
+> The value `"0.0.0.0/0"` in `metrics_whitelist` opens access to metrics from any IP address. It is recommended to replace it with your personal IP, for example: `"1.2.3.4/32"`.
 
 ## Additional parameters
 
-### Domain in link instead of IP
+### Domain in the link instead of IP
-To specify a domain in the links, add to the `[general.links]` section of the config file.
+To display a domain instead of an IP address in the connection links, add the following lines to the configuration file:

 [general.links]
 public_host = "proxy.example.com"

-### Server connection limit
+### Total server connection limit
-Limits the total number of open connections to the server:
