# Setting up Appservice IRC (optional)
The playbook can install and configure [matrix-appservice-irc ](https://github.com/TeDomum/matrix-appservice-irc ) for you.
See the project's [documentation ](https://github.com/TeDomum/matrix-appservice-irc/blob/master/HOWTO.md ) to learn what it does and why it might be useful to you.
You'll need to use the following playbook configuration:
```yaml
matrix_appservice_irc_enabled: true
matrix_appservice_irc_configuration_extension_yaml: |
# Your custom YAML configuration for Appservice IRC servers goes here.
# This configuration extends the default starting configuration (`matrix_appservice_irc_configuration_yaml`).
#
# You can override individual variables from the default configuration, or introduce new ones.
#
# If you need something more special, you can take full control by
# completely redefining `matrix_appservice_irc_configuration_yaml` .
#
# For a full example configuration with comments, see `roles/matrix-synapse/defaults/main.yml`
#
# A simple example configuration extension follows:
#
ircService:
databaseUri: "nedb:///data" # does not typically need modification
passwordEncryptionKeyPath: "/data/passkey.pem" # does not typically need modification
matrixHandler:
eventCacheSize: 4096
servers:
irc.example.com:
name: "ExampleNet"
port: 6697
ssl: true
sasl: false
allowExpiredCerts: false
sendConnectionMessages: true
botConfig:
enabled: true
nick: "MatrixBot"
joinChannelsIfNoUsers: true
privateMessages:
enabled: true
federate: true
dynamicChannels:
enabled: true
createAlias: true
published: true
joinRule: public
groupId: +myircnetwork:localhost
federate: true
aliasTemplate: "#irc_$CHANNEL"
membershipLists:
enabled: false
floodDelayMs: 10000
global:
ircToMatrix:
initial: false
incremental: false
matrixToIrc:
initial: false
incremental: false
matrixClients:
userTemplate: "@irc_$NICK"
displayName: "$NICK (IRC)"
joinAttempts: -1
ircClients:
nickTemplate: "$DISPLAY[m]"
allowNickChanges: true
maxClients: 30
idleTimeout: 10800
reconnectIntervalMs: 5000
concurrentReconnectLimit: 50
lineLimit: 3
```
You then need to start a chat with `@irc_bot:{{ hostname_identity }}`
