-In this case, EUDAQ2 itself depends on [Peary](https://gitlab.cern.ch/Caribou/peary), which is the data acquisition software accompanying the Caribou readout system.
-To switch off all interfaces that are not necessary when not operating devices, one can do:

-__Note:__ For an installatin on `lxplus` it is recommended to `source path/to/corryvreckan/etc/setup_lxplus.sh` not only before the installation of Corryvreckan but also before starting with the installation of EUDAQ2 to make sure the same compiler version is used for all libraries.
-If also Peary is installed, the following order is recommended:
-
-1. `source path/to/peary/.gitlab-ci.d/init_x86_64.sh`
-2. install Peary as described [here](https://peary-caribou.web.cern.ch/peary-caribou/#compilation-installation)
-3. `source path/to/corryvreckan/etc/setup_lxplus.sh`
-4. install EUDAQ2 as described [here](https://github.com/eudaq/eudaq/)
-5. install Corryvreckan
+__Note:__
+It is important to make sure that the same compiler version is used for the installation of Corryvreckan and all its dependencies such as EUDAQ2 (if enabled).
+On `lxplus` this is achieved by running `source path/to/corryvreckan/etc/setup_lxplus.sh` before beginning the installation.
