A log message containing the invite link will be printed out every time the bridge is started. Launch the bridge and click the link in the log and follow the prompts on discord's website to add the bridge's bot to your guild.
Once it has joined your server, create a text channel for it to post in, then press the "Edit Channel" button on that channel. From there, press the "Permissions" button and click the "+" button and add "Minecraft Chat Bridge" to the room and close the permissions window.
