You can find documentation for installing, configuring, and using iamb on its website, iamb.chat.

You can create a basic configuration in $CONFIG_DIR/iamb/config.toml that looks like:

[profiles."example.com"]
user_id = "@user:example.com"

If you homeserver is located on a different domain than the server part of the user_id and you don't have a /.well-known entry, then you can explicitly specify the homeserver URL to use:

[profiles."example.com"]
url = "https://example.com"
user_id = "@user:example.com"

Install Rust (1.74.0 or above) and Cargo, and then run:

cargo install --locked iamb
