-## Usage
+## Usage of this module
 
 This module runs `tailscaled` with the following command:
 
 ```bash
 tailscaled -tun=userspace-networking -statedir=/data/adb/tailscale/tmp/ -state=/data/adb/tailscale/tmp/tailscaled.state -socket=/data/adb/tailscale/tmp/tailscaled.sock -port=41641
 ```
-This command uses a userspace network stack instead of the kernel's network stack, which can be useful on devices where the kernel's network stack is not compatible with Tailscale. The state file for tailscaled is stored at `/data/adb/tailscale/tmp/tailscaled.state`, and the log output is written to `/data/adb/tailscale/run/tailscaled.log`.

-## Troubleshooting
+## FAQ & Troubleshooting
 
-Tailscale has some known issues. You can check them out [here](https://github.com/tailscale/tailscale/issues?q=no+safe+place+found+to+store+log+state).
+Tailscale has manny issues. You can check them out [here](https://github.com/tailscale/tailscale/issues).
 
-In order to execute any Tailscale command on the terminal, you must navigate to the directory `/data/adb/tailscale/tmp/` and then execute the Tailscale command. For example, `cd /data/adb/tailscale/tmp/` then `tailscale login`, or `tailscale status`.
+#### Cannot access other tailnet devices
 
-To address this issue, I have created mock versions of `tailscale` and `tailscaled`. Now, you can run `tailscale login` directly without needing to navigate to the `/data/adb/tailscale/tmp/` directory.
+This module runs the `tailscaled` binary in userspace-networking mode. To access other devices in the tailnet, you must use a local proxy on port 1099. I've implemented a workaround using `hev-socks5-tunnel` to tunnel local socks5 on port 1099 and bind it to the interface named `tailscale0`. 
 
-If you encounter any problems, take a look at the `service.sh` file. You can modify the commands that are not necessary. If you make some modifications to the commands and they work, please open an issue and make a report.
+Please note, this `tailscale0` interface is different from the original `tailscale0` interface on Linux. In Linux, `tailscale0` is managed by the `tailscaled` daemon, whereas in this module, `tailscale0` is managed by `hev-socks5-tunnel`. The default gateway is `100.100.100.100`, as defined in the `tailscaled.tun.config.yaml` file.
 
-This module is confirmed to be supported for KernelSU, as [confirmed by the author of KernelSU](https://github.com/anasfanani/Magisk-Tailscaled/issues/2#issue-2055047162). If you encounter any problems, please let me know.
+This solution should work on most common devices. However, if you encounter problems accessing other tailnet devices, follow these troubleshooting steps:
+
+1. Verify that `tailscaled.service` is running. If not, restart it with `tailscaled.service restart`.
+2. Verify that `tailscaled.tun` is running. If not, restart it with `tailscaled.tun restart`.
+3. Check if your device is connected to tailscaled and try a ping connection with `tailscale ping <your_tailnet_ip>`.
+4. Verify the port you want to access is accessible. You can do this by accessing it with another tailscale device or using the Tailscale Android App.
+5. Check if the local socks5 server is working with curl. Execute the following command:
+  ```
+  curl 1.1.1.1 -vI -x localhost:1099
+  ```
+  If it connects, then the local socks5 server is running and working.
+6. Check if the local socks5 server can connect to the tailnet network.
+  ```
+  curl <your_tailnet_ip>:<port> -vI -x localhost:1099
+  ```
+  If it connects, then the local socks5 server is functioning correctly.
+7. Finally, check the connection directly with `curl <your_tailnet_ip>:<port> -vI`.
+
+If the last step fails, the problem likely lies with `socks5-tun`. Verify there is an interface named `tailscale0`. If it exists, the problem may be with the iptables route, either due to a conflict with another rule or some other issue. Feel free to explore your own solutions. If you're unable to resolve the issue, contact me on Telegram and I'll see if I can assist you.
+
+#### My subnet-routes is'nt working
+
+Yes because we need define the routes with `iptables` in file `tailscaled.tun.up` and `tailscaled.tun.down`, you can check this [issue reference](https://github.com/anasfanani/Magisk-Tailscaled/issues/17).
+I suppose you're already know the iptables works, if dont, there are chatAI to ask.
+You can copy whole `tailscaled.tun.up` script to chatAI and send instruction with please add 192.168.1.1/24 to this route, also dont forget `tailscaled.tun.down` 
+
+If you still can't do it by yourself, I'm verry welcome to people who needs help.
+
+#### Exit nodes
+
+You can check this [issue reference](https://github.com/anasfanani/Magisk-Tailscaled/issues/17).
+
+#### ipv6
 
-If you encounter any issues, you can check the logs at `/data/adb/tailscale/tmp/tailscaled.log`.
+Unfortunately, I'm verry lazy to learn ipv6.
+
+#### Headscale 
+
+Check [this](https://github.com/anasfanani/Magisk-Tailscaled/issues/19#issuecomment-2091579177).
+Also explore on the issue first, then you can ask trough telegram.
+
+
+#### Other Error & Bugs
+
+You can explore to the issue tab, if there not exists, you can open issue, for help me resolve the problem, you can include fresh log.
+
+1. Restart tailscaled with `tailscaled.service restart`
+2. Reproduce what are you doing which has problem.
+3. Get log at `/data/adb/tailscale/run/tailscaled.log`
