+- **Project Goal:** Make it simple to run a Hotline server on macOS, Linux, and Windows, with full compatibility for all popular Hotline clients.

 
 

-The goal of the Mobius client is to make it fun and easy to connect to multiple Hotline servers through a [cool retro terminal UI](https://github.com/jhalter/mobius/wiki/Mobius-Client-Screenshot-Gallery).

 
 

-## Getting started
+## Installation
+
+Mobius is distributed through a single binary.
+
+Depending on your platform and preferences, you can acquire the binary in the following ways:
+
+### Build from source
+
+1. Install [Go](https://go.dev) if needed
+2. Run `make server`
+
+### Download pre-built release
+
+See [Releases](https://github.com/jhalter/mobius/releases) page.

-You'll now find a configuration directory on your host OS populated with a default configuration:
+### Homebrew
+
+For macOS the easiest path to installation is through Homebrew, as this works around Apple's notarization requirements for downloaded pre-compiled binaries by compiling the binary on your system during brew installation.
+
+To install the server:
+
+    brew install jhalter/mobius-hotline-server/mobius-hotline-server
+
+After installation `mobius-hotline-server` will be installed at `$HOMEBREW_PREFIX/bin/mobius-hotline-server` and should be in your $PATH.
+
+The server config directory will be created under `$HOMEBREW_PREFIX/var/mobius`.
+
+To start the service:
+
+`brew services start mobius-hotline-server`
+
+
+## Server Configuration
+
+After you have a server binary, the next step is to configure the server.
+
+### Configuration directory
+
+Mobius stores its configuration and server state in a directory tree:

 
 ```
 
 ```

-Edit `config.yaml` to get started personalizing your server.
+If you acquired the server binary by downloading it or compiling it, this directory doesn't exist yet!  But you can generate it by running the the server with the `-init` flag:

 
 

-### Mac OS
+`./mobius-hotline-server -init -config example-config-dir`

 
 

-For Mac OS the easiest path to installation is through Homebrew.
+Brew users can find the config directory in `$HOMEBREW_PREFIX/var/mobius`.

 
 

-#### Client
+Within this directory some files are intended to be edited to customize the server, while others are not.

 
 

-To install the client:
+--- 

 
 

-    brew install jhalter/mobius-hotline-client/mobius-hotline-client
+* 🛠️ Edit this file to customize your server.
+* ⚠️ Avoid manual edits outside of special circumstances (e.g. remove offending news content).

 
 

-Then run `mobius-hotline-client` to get started.
+---

 
 

-#### Server
+🛠️ `Agreement.text` - The server agreement sent to users after they join the server.

 
 

-To install the server:
+🛠️ `Files` - Home of your warez or any other files you'd like to share.

 
 

-    brew install jhalter/mobius-hotline-server/mobius-hotline-server
+⚠️ `MessageBoard.txt` - Plain text file containing the server's message board.  No need to edit this.

 
 

-After installation `mobius-hotline-server` will be installed at `$HOMEBREW_PREFIX/bin/mobius-hotline-server` and should be in your $PATH.
+⚠️ `ThreadedNews.yaml` - YAML file containing the server's threaded news.  No need to edit this.

 
 

-The server config file directory is under `$HOMEBREW_PREFIX/var/mobius` which by default contains:
+⚠️ `Users` - Directory containing user account YAML files.  No need to edit this.

-Edit `/usr/local/var/mobius/config/config.yaml` to change your server name and other settings.
+🛠️ `config.yaml` - Edit to set your server name, description, and enable tracker registration.

 
 

-Edit `/usr/local/var/mobius/config/Agreement.txt` to set your server agreement.

 
 

-Run `mobius-hotline-server -help` for usage options.
+### User accounts

 
 

-### Linux
+The default installation includes two users: 

 
 

-Download a compiled release for your architecture from the Releases page or follow build from source instructions
+* guest (no password) 
+* admin (default password admin).

 
 

-### Windows
+User administration should be performed from a Hotline client.  Avoid editing the files under the `Users` directory.

 
 

-    TODO
+## Run the server

 
 

-### Build from source
+By default running `mobius-hotline-server` will listen on ports 5500/5501 of all interfaces with info level logging to STDOUT.

 
 

-To build from source, run:
+Use the -h or -help flag for a list of options:

 
 

-    make all
+```
+$ mobius-hotline-server -h
+Usage of mobius-hotline-server:
+  -bind int
+       Base Hotline server port.  File transfer port is base port + 1. (default 5500)
+  -config string
+       Path to config root (default "/usr/local/var/mobius/config/")
+  -init
+       Populate the config dir with default configuration
+  -interface string
+       IP addr of interface to listen on.  Defaults to all interfaces.
+  -log-file string
+       Path to log file
+  -log-level string
+       Log level (default "info")
+  -stats-port string
+       Enable stats HTTP endpoint on address and port
+  -version
+       Print version and exit
+```
+
+
+To run as a systemd service, refer to this sample unit file: [mobius-hotline-server.service](https://github.com/jhalter/mobius/blob/master/cmd/mobius-hotline-server/mobius-hotline-server.service)
+
+## (Optional) HTTP API
+
+The Mobius server includes an optional HTTP API to perform out-of-band administrative functions.
+
+To enable it, include the `--api-port` flag with a string defining the IP and port to listen on in the form of `<ip>:<port>`.
+
+Example: `--api-port=127.0.0.1:5503`
+
+⚠️ The API has no authentication, so binding it to localhost is a good idea!
+
+#### GET /api/v1/stats
+
+The stats endpoint returns server runtime statistics and counters.
+
+```
+❯ curl -s localhost:5603/api/v1/stats  | jq .
+{
+  "ConnectionCounter": 0,
+  "ConnectionPeak": 0,
+  "CurrentlyConnected": 0,
+  "DownloadCounter": 0,
+  "DownloadsInProgress": 0,
+  "Since": "2024-07-18T15:36:42.426156-07:00",
+  "UploadCounter": 0,
+  "UploadsInProgress": 0,
+  "WaitingDownloads": 0
+}
+```

 
 

-Then grab your desired build from `dist`
+#### GET /api/v1/reload
+
+The reload endpoint reloads the following configuration files from disk:
+
+* Agreement.txt
+* News.txt
+* Users/*.yaml
+* ThreadedNews.yaml
+* banner.jpg
+
+Example:
+
+```
+❯ curl -s localhost:5603/api/v1/reload | jq .
+{
+  "msg": "config reloaded"
+}
+```
+
+#### POST /api/v1/shutdown
+
+The shutdown endpoint accepts a shutdown message from POST payload, sends it to to all connected Hotline clients, then gracefully shuts down the server.
+
+Example:
+
+```
+❯ curl -d 'Server rebooting' localhost:5603/api/v1/shutdown
+
+{ "msg": "server shutting down" }
+```
