Looks good, can we sneak peek the GitHub pages already?

I've changed the main branch to this one in the Pages settings, so that should be reverted when this gets merged. This is the landing page: https://sysbiochalmers.github.io/GECKO/

[mihai-sysbio]

It this ready do be merged? And if so, do we want it to go develop first?

[edkerk]

Yes & yes, so that develop and main are in sync.
