+## How to use gogo companion:
+
+
+#### Dependencies
+
+ОС: Linux, Mac, Windows
+Shell: bash
+
+
+#### Installation
+
+- download or copy the script from the root of the repository `/scripts/gogo/gogo.sh`
+- to call the script without specifying the full path, put it in the directory that is in $PATH (in the future, I assume that you will have it `~/.local/bin/`)
+
+```console
+curl https://git.isptech.ru/ISPsystem/isp-maintenance/raw/branch/main/scripts/gogo/gogo.sh -o ~/.local/bin/gogo && chmod u+x ~/.local/bin/gogo
+```
+
+#### Configuration
+
+For the script to work, you need a configuration file with settings `~/.config/gogo/gogo.conf`
+
+This config contains the following fields that are read every time you start
+
+```
+GO_SERVER_ADDR_RUSSIAN=
+GO_SERVER_ADDR_GERMANY=
+GO_SERVER_ADDR_TEST=
+VAULT_SERVER_ADDR=
+SSH_PRIVATE_KEY_USER=
+SSH_PRIVATE_KEY_PATH=
+SSH_PUBLIC_KEY_PATH=
+SSH_CRT_FILE=
+MGRCTL_IMAGE=mois3y/mgrctl:latest
+DEBUG_MODE=false
+```
+
+Please fill in the fields with current data, write the path to the keys and certificate in full `/home/username/.ssh/id_ecdsa` and so on.
+For security reasons, server addresses and paths to keys are not indicated here.
+
+For your convenience, the config can be filled out interactively
+
+```console
+gogo --init
+```
+
+
+#### Usage
+
+- Get a temporary ssh certificate
+
+```console
+gogo --crt
+```
+
+- Check your connection to test servers in both locations
+
+```console
+gogo --test
+```
+
+- If the connection is successful, you can use the script. You are beautiful!
+
+
+#### Examples
+
+- Connect to BILLmanager 6 via ssh port 22 and interface port 443
+
+```console
+gogo --bill my.example.com
+```
+or
+```console
+gogo --bill my.example.com -p 22 -wp 443
+```
+
+- Connect to BILLmanager 6 again without generating an access key to the interface
+
+```console
+gogo --bill my.example.com --ssh
+```
+
+- Connect to DNSmanager 6 via ssh port 22 and interface port 1501
+
+```console
+gogo --dns my.example.com -p 22 -wp 1501
+```
+
+- Connect to DCImanager 6 via ssh port 2222 and interface 443 port
+
+```console
+gogo --dci vm.example.com -p 2222
+```
+
+- Connect to VMmanager 6 via ssh port 2222 and interface port 443
+
+```console
+gogo --vm 228.228.228.228 -p 2222
+```
+
+- Connect to VMmanager 6 via ssh port 22 and interface port 443, indicating the id of a specific user and generate 3 keys
+
+```console
+gogo --vm vm.example.com --mgrctl auth user access --id 1488 --count 1
+```
+
+- The same thing, just print the command that is executed on the server side into the console, you can run it later simply by copying it
+
+```console
+gogo --vm vm.example.com --tty --mgrctl auth user access --id 1488 --count 1
+```
+
+
+Connect to VMmanager 6 via ssh port 22 and interface port 443 via DE go3 server
+
+```console
+gogo --vm vm.example.com -p 22 --de
+```
+
+Connect to DCImanager 6 via ssh port 22 and interface port 443 via the old go method
+
+```console
+gogo --dci dci.example.com -p 22 --go
+```
+
+##### There are also examples in `help`
+
+```console
+gogo --help
+
+Usage: gogo [options [parameters]]
+
+Examples:
+
+gogo --init | init config file
+gogo --crt  | get ssh certificate for go3 connections
+gogo --test | check go3 connection availability
+
+gogo --bill my.example.com
+gogo --vm my.example.com --de  | connect throw DE go3 server
+gogo --vm 0.0.0.0 --ssh | only ssh access
+gogo --vm 0.0.0.0 --tty | use mgrctl interactive
+
+gogo --dci 0.0.0.0 --mgrctl auth user access --id 3 --count 5
+gogo --dci 0.0.0.0 --mgrctl auth user ls --admins
+gogo --vm 0.0.0.0 --port 22122 --mgrctl auth user ls --admins
+gogo --vm 0.0.0.0 --tty --mgrctl auth user ls --admins
+gogo --dns ns1.example.com --web-port 1501
+gogo --dns ns1.example.com --port 22122 --web-port 1501
+gogo --bill my.example.com --port 22 --web-port 1501
+
+Options:
+
+ --vm[dci|bill|dns|ip] expected ip_addr             required
+ --port     | -p    ssh port,   default 22
+ --web-port | -wp   web port,   default 443
+ --go/--go3         go version, default go3
+ --de               connect throw DE go3 server
+ --ssh              open only ssh session
+ --tty              for vm6/dci6 echo cmd for run container
+ --mgrctl [args]    for vm6/dci6 customize access params
+
+Single options:
+ --init     | -i    generate configuration
+ --crt      | -c    generate ssh cert
+ --test     | -t    check go3 connection availability
+ --version  | -v    print version
+ --help     | -h    print this message and exit
+```
