Google Docs + Lucidcharts. The Docs format works well as the organisation is deeply embedded in Google Suite and Lucidcharts allows me to quickly produce architectural diagrams.Code snippets and other information can be formatted to make it easy to read and I use links where required to other technical documentation where required.

Is lucid chart integrated in google documents? (as in anybody editing the document can edit the chart)

There's a Google Docs plugin to embed them. They are not very clear in the doc but you can see a good outline and link through to the actual chart for viewing.
