Minimalistic wiki?

Hey there,

we are looking for a minimalistic wiki software, preferably hosted in the cloud. Maybe not even a full wiki? We want to document internal processes, on-boarding documents for new employees, internal software documentation, infrastructure documentation. We used google docs so far, but it's hard to structure that.

Confluence is too big for us, in the past I used Dokuwiki mostly, but that's self-hosted.

Any ideas? (Feel free to post what you are doing, even if it's not wiki!)
