 # Initiative-bot
 A simple bot for Discord, that can track initiative in D&D and similar TTRPGs, based on alternative systems - such as 
-Speed Factor from DMG or Greyhawk initiative from Unearthed Arcana. 
+Speed Factor from DMG (currently supported) or Greyhawk initiative from Unearthed Arcana (TBD). 
 
-## Commands:
+## Common commands:
 * `!ib start` - start initiative
 * `!ib end` - stop initiative, if it was started
+* `!ib help` - display help message
+
+## Commands for Speed Factor variant:
 * `!ib add <base modifier> [name]` - add a participant `name` (defaults to username) with base initiative modifier
 * `!ib remove [name]`
-* `!ib round` - start a new round
-* `!ib end-round` - end the round
-* `!ib roll <modifier> [name]` (`name` defaults to the username) - rolls initiative for the current round, combining `modifier` and base modifier
-* `!ib mods` - show modifiers for different actions
+* `!ib round` - start a new round, but only if every combatant has rolled a new initiative
+* `!ib end-round` - end the round, enable combatants edit and rolling
+* `!ib roll <modifier> [name]` (`name` can be omitted if user has added a single character) - rolls initiative for the current round, adds `modifier` and base modifier
 
 ## Usage
-To start encounter, DM calls `start` command. All combatants join using `add` command, stating their base modifiers. DM then starts
-a new round using `round` command. All combatants should state their actions and roll for initiative using 
-`!ib roll <modifier> [name]` command. Once everyone (i.e., all, who has joined previously) has rolled, the bot will ask the first combatant
-to act. Once everyone has acted, the new round begins. If needed, list of combatants can be altered using `add` and `remove` commands.
-The bot stores the list of combatants from the previous rounds and won't let the new round start, unless everyone has rolled.

+# Build and run
+This app requires Java installation of version 1.8 or greater.
+To build the app, run `./gradlew build`.
+
+To run it for your own server, you'll need to register a new discord app and obtain a token for it. Once this is done, you can either
+* run initiative-bot-discord with gradle, run `./gradlew :initiative-bot-discord:run --args="<your discord token>"`.
+* build distribution using `./gradlew :initiative-bot-discord:installDist` and run an executable script from `initiative-bot-discord/build/install/initiative-bot-discord-<version>/bin`.
+* download a distribution zip from Github releases, unpack it and run an executable script
