+# Content.DiscordBot
+
+
+### Configuration (Debug)
+* `DISCORD_TOKEN`: Discord application token provided @ `https://discord.com/developers/applications/<APP_ID>/bot`
+* `DATABASE_STRING`: Connection string to the database
+  * For local development, you'll want it to be `Data Source=./bin/Content.Server/data/preferences.db` if you're using sqlite.
+* `DATABASE_CONTEXT`: Default is `postgres`. If testing locally with sqlite, use `sqlite`.
+* `GUILD`: The Discord Server ID. DeltaV's discord is `968983104247185448`.
+    * You can find this by turning Developer mode on in Discord, right-clicking on a server, and copying the server ID.
+
+### Configuration (Production)
+Requires a `link-config.json` file in the working directory.
+```json
+{
+    "Token": "DISCORD_BOT_TOKEN",
+    "DatabaseString": "DB_CONNECTION_STRING"
+}
+```
+
+Here's a quick bash command to create it in your current working directory. Windows users will have to fend for themselves.
+```bash
+cat << EOF > link-config.json
+{
+    "Token": "DISCORD_BOT_TOKEN",
+    "DatabaseString": "DB_CONNECTION_STRING"
+}
+EOF
+```
+
+You can also override `Guild` and `DatabaseContext` if you wanted to by including those JSON properties.
