 A small utility for launching a SA:MP server with better settings handling.
 
-May include subcommands for common tasks too.
+## Usage
 
-Proposed usage:
+`sampctl run` Will run a server in your current directory. If there are no binaries, it will automatically download them.
 
-`sampctl --gamemode0=ScavengeSurvive --filterscripts="rcon,objectloader,base" --rcon_password="0xdeadbeef"`
+`sampctl download` Just downloads the binaries to the current directory.
 
-And env vars
+## Config
 
-`GAMEMODE0=ScavengeSurvive FILTERSCRIPTS=rcon,objectloader,base RCON_PASSWORD=0xdeadbeef sampctl`
+If your current directory has a JSON file named `samp.json`, the values will be used to generate a `server.cfg` file. The setting names are the same.
 
-Or JSON/Yaml too probably
+You can also use environment variables to configure, just prefix them with `SAMP_` and uppercase the rest.
 
-`sampctl --config=server.json`
+For example: `rcon_password`'s environment variable is `SAMP_RCON_PASSWORD`.
 
-As well as some other nice features like log rotation, pre-flight checks for common mistakes and watchdog restarts.
+## Crashloops and Exponential Backoff
+
+Crashes, crashlooks and backoff timing is handled by the app. If the server crashes, it will be restarted. If it crashes repeatedly, it will be restarted with an exponentially increasing amount of time between tries - in case it's waiting for a database to spin up or something. Once the backoff time reaches 15s, it quits.
+
+## Roadmap
+
+The main focus of this project was to bring SA:MP server management into the present with a modern system `*ctl` tool (think systemd, kubectl, caddy, etc).
+
+Another primary focus was to ease the use of SA:MP in a Docker container, this project is at: https://github.com/Southclaws/docker-samp
+
+The future will include:
+
+- processing of logs to extract meaningful information such as runtime errors
+- a RESTful API to control the server that's better than RCON in every possible way
+- auto-restart when gamemode .amx files are updated
