Front derailleur

On my way in this morning the chain hopped off the front crank, now I can’t get it to shift to the large crank.

How do I adjust, sorry for the probably silly question but I leave gear adjustment to the pros usually.

Edit: when I lean the bike over towards the side with the gears it’s will change it, if that info helps.

Hard to tell from that angle but it may have thrown the front mech out of alignment.

Let me get a top down view, I fixing a puncture at the moment, thanks broken glass!

It's a derailleur that has a mount on the frame, would be mean it's hard to throw out of alignment?

Sorry didn't see it was a braze on type so the alignment would be fixed. You can only adjust the height. Follow the video and you should have things working correctly.

Also I learnt the correct term for the mount!

I really should do one of the basic maint courses I keep seeing LBS advertising.

For those who need to learn about bike mechanics, there are loads of video stuff on you tube. Alternatively, the bike book by Haynes gives step by step instructions with loads of pictures.

A braze on can be twisted, it sits on a radiused bracket so alignment can be set.

The alignment looks OK though so it may be cable tension, just increase it slightly but TBH I'd check everything was right if it 'unshipped' the chain, if you're not confident take it to a shop though.
