+# Sea battle backend
+[![Build Status](https://drone.communiquons.org/api/badges/pierre/SeaBattle/status.svg)](https://drone.communiquons.org/pierre/SeaBattle)
+[![Crate](https://img.shields.io/crates/v/sea_battle_backend.svg)](https://crates.io/crates/sea_battle_backend)
+[![Documentation](https://docs.rs/sea_battle_backend/badge.svg)](https://docs.rs/sea_battle_backend/)
+
+A backend HTTP server for the Sea Battle game. The binary included in
+this crate can be used to deploy a server that will allow players to
+connect to play together.
+
+The `actix-web` library is used to spawn HTTP server. The games are encapsulated
+inside websockets.
+
+An official server is running at https://seabattleapi.communiquons.org/
+
+## Installation
+You can install the backend using the following command:
+
+```bash
+cargo install sea_battle_backend
+```
+
+## Usage
+```bash
+sea_battle_backend -l 0.0.0.0:7000
+```
+
+> Note: a reverse-proxy must be used to protect
+
+## Client
+A command-line client is available in the [sea_battle_cli_player](https://crates.io/crates/sea_battle_cli_player) crate.

+
+A sea battle shell client player for the [sea_battle_backend](https://crates.io/crates/sea_battle_backend) crate, based on the [tui](https://crates.io/crates/tui) library.
+
+## Available play modes
+* 🤖 Play against bot (this mode does not require any Internet connection, a local server is automatically spawn)
+* 🎲 Play against a random player
+* ➕ Create play invite (online). In this mode, the server returns an invitation code to give to the opponent
+* 🎫 Accept play invite (online)
+
+For the 🤖 bot and ➕ create invite modes, game rules can be customized before starting the game.
+
+## Installation
+You can install the backend using the following command:
+
+```bash
+cargo install sea_battle_cli_player
+```
+
+## Usage
+Simply launch using:
+```bash
+sea_battle_cli_player
+```
+
+
+## Offline LAN
+If you want to run a local server to play offline LAN games, the cli player can also act as the server:
+```bash
+RUST_LOG=info sea_battle_cli_player -s -l 0.0.0.0:7000
+```
+
+Then all the players must specify the address of this server to use it instead of the default official one:
+```bash
+sea_battle_cli_player -r http://IP_OF_TARGET:7000
+```
