 ## Installation

-### Disclaimer
-
-This tool uses external calls for `bash`, `coreutils` and `easy-rsa`, thus **Linux systems only are supported** at the moment.

 ### 1. Docker

 There is a ready-to-use [docker-compose.yaml](https://github.com/flant/ovpn-admin/blob/master/docker-compose.yaml), so you can just change/add values you need and start it with [start.sh](https://github.com/flant/ovpn-admin/blob/master/start.sh).

-Requirements. You need [Docker](https://docs.docker.com/get-docker/) and [docker-compose](https://docs.docker.com/compose/install/) installed.

+You can also download and use prebuilt binaries from the [releases](https://github.com/flant/ovpn-admin/releases/latest) page — just choose a relevant tar.gz file.

-To use password authentication (the `--auth` flag) you have to install [openvpn-user](https://github.com/pashcovich/openvpn-user/releases). This tool should be available in your `$PATH` and its binary should be executable (`+x`).
+
+## Notes
+* this tool uses external calls for `bash`, `coreutils` and `easy-rsa`, thus **Linux systems only are supported** at the moment.
+* to enable additional password authentication provide `--auth` and `--auth.db="/etc/easyrsa/pki/users.db`" flags and install [openvpn-user](https://github.com/pashcovich/openvpn-user/releases/latest). This tool should be available in your `$PATH` and its binary should be executable (`+x`).
+* master-replica synchronization does not work with `--storage.backend=kubernetes.secrets` - **WIP**
+* additional password authentication does not work with `--storage.backend=kubernetes.secrets` -  **WIP**
+* if you use `--ccd` and `--ccd.path="/etc/openvpn/ccd"` abd plan to use static address setup for users do not forget to provide `--ovpn.network="172.16.100.0/24"` with valid openvpn-server network 
+* tested only with Openvpn-server versions 2.4 and 2.
+* status of users connections update every 28 second(*no need to ask why =)*)
