Hi, Some time in the last hour or two all the online documentation for GMT has disappeared. I know I should have downloaded it locally for my reference, but the online site is so convenient. For example, I get a 404 error for this: [https://docs.generic-mapping-tools.org/dev/grdproject.html](https://docs.generic-mapping-tools.org/dev/grdproject.html) Cheers, Tim ---

Yes, I too seem to can not find online documentation, and I needed to refer to it on an urgent basis. Hope it comes online soon… ---

Yeah. The one day in the last year when I really needed it was today. But there’s some law that says that’s how things go isn’t there? Still: gmt command --help (e.g. gmt grdproject --help) works, but not as well as the web pages in my opinion. ---

If you have the source you can build the docs yourself. But agree, very inconvenient. Doesn’t happen often though. ---

Thanks to @seisman the documentation is back online. ---

It’s nice that this problem was noticed so fast - people must be using the docs. ---

I used to keep a binder full of GMT man pages (last printed in 2015). I use the on-line docs ALL the time, now. I feel very green not wasting paper, anymore. I still have the binder, because it is filled with tons of notes on how to do things.
