-This template comes with an Antora documentation module to help you create Asciidoctor documentation.
-By default, it is automatically published to GitHub Pages in `gh-pages` branch, however it can also be included in external Antora playbooks.
-
-### Setup GitHub Pages
+```
+NAME:
+   tcp-over-socks - Connect TCP over SOCKS5
 
-Once you generated a new repository using this template, the initial commit automatically runs a Job that creates the documentation in the `gh-pages` branch.
-All you need to do is then to enable Pages in the settings.
+USAGE:
+   tcp-over-socks [global options] command [command options] [arguments...]
 
-The `gh-pages` branch is a parent-less commit that only contains the Antora-generated files.
+COMMANDS:
+   help, h  Shows a list of commands or help for one command
 
-However, if that's not the case or if you are setting up Antora in an existing repository, here's how you can achieve the same, but make sure to **commit or stash current changes first!**
-```bash
-current_branch=$(git rev-parse --abbrev-ref HEAD)
-initial_commit=$(git rev-list --max-parents=0 HEAD | tail -n 1)
-git switch --create gh-pages $initial_commit
-git rm -r --cached .
-git commit -m "Prepare gh-pages branch"
-git push --set-upstream origin gh-pages
-git switch -f $current_branch
+GLOBAL OPTIONS:
+   --port value, -p value    local listen port (default: 12345)
+   --socks5 value, -x value  socks5 server (default: "127.0.0.1:1080")
+   --target value, -t value  target address including port
+   --help, -h                show help (default: false)
 ```
 
-And you're done!
-GitHub automatically recognizes activity and sets up Pages if there's a `gh-pages` branch.
-
----
+## Running in Kubernetes / OpenShift
 
-If you want to skip deployment to GitHub Pages you need to delete specific files and references:
-`rm -f .github/workflows/docs.yml docs/package*.json docs/antora-playbook.yml docs/antora-build.mk`.
-Also don't forget to delete the branch and disable Pages in the repository settings.
+See files in `examples/`.
 
----
+## Credits
 
-If you want to remove documentation completely simply run `rm -rf docs .github/workflows/docs.yml`.
+Original work done by @isayme in https://github.com/isayme/go-tcp-over-socks5.
+Thank you very much for the inspiration!
