 2. Check to make sure LURE is properly installed by running `lure ref`.
 3. Run `lure in itgui`. This process may take a while as it will compile `itgui` from source and package it for your distro.

-### Installation
-
-To install, install the go compiler and make. Usually, go is provided by a package either named `go` or `golang`, and make is usually provided by `make`. The go compiler must be version 1.17 or newer for various new `reflect` features.
-
-To install, run
-```shell
-make && sudo make install

 ### Socket
 
 This daemon creates a UNIX socket at `/tmp/itd/socket`. It allows you to directly control the daemon and, by extension, the connected watch.
