-# telegram-bot-api
+# Golang Telegram bot using the Bot API
 A simple Golang bot for the Telegram Bot API
 
-Really simple bot for interacting with the Telegram Bot API, not nearly done yet. 
+Really simple bot for interacting with the Telegram Bot API, not nearly done yet. Expect frequent breaking changes!
 
-All API responses are implemented as structs, only some method calls have been added. 
+All methods have been added, and all features should be available.
-There's a very simple plugin in `bot.go` right now. You can find config options in the code fairly easily. 
+If you want a feature that hasn't been added yet, open an issue and I'll see what I can do.
 
-Hopefully code quality will improve as this project progresses. 
+There's a few plugins in here, named as `plugin_*.go`.
+
+## Getting started
+
+After installing all the dependencies, run
+
+```
+go build
+./telegram-bot-api -newbot
+```
+
+Fill in any asked information, enable whatever plugins, etc.
+
+## Plugins
+
+All plugins implement the `Plugin` interface.
+
+```go
+type Plugin interface {
+	GetName() string
+	GetCommands() []string
+	GetHelpText() []string
+	GotCommand(string, Message, []string)
+	Setup()
+}
+```
+
+`GetName` should return the plugin's name. This must be unique!
+
+`GetCommands` should return a slice of strings, each command should look like `/help`, it must have the forward slash!
+
+`GetHelpText` should return a slice of strings with each command and usage. You many include any number of items in here.
+
+`GotCommand` is called when a command is executed for this plugin, the parameters are the command name, the Message struct, and a list of arguments passed to the command. The original text is available in the Message struct.
+
+`Setup` is called when the bot first starts, if it needs any configuration, ask here.
+
+To add your plugin, you must edit a line of code and then run the `go build` again.
+
+```go
+// current version
+plugins = []Plugin{&HelpPlugin{}, &ManagePlugin{}}
+
+// add your own plugins
+plugins = []Plugin{&HelpPlugin{}, &FAPlugin{}, &ManagePlugin{}}
+```
