hey, I have completed your saas project video but I'm having some issues while hosting it on the railway, you explained it very well but at the end of the videos things got too fast. I do not understand which new variables I must add to the railway. also, the custom CSS theme you provided is causing some problems with Flowbite components i mean if I add any new footer components they get misaligned. if you can please add a short video at the end of that saas video, it will help a lot :)

Can one start with langchain without any prior coding experience

[nextgodlevel]

I am a superhero fan. and I see superhero's everywhere.
In coding industry you are my THOR.

[spotnuru]

this is really great and you are giving very good teachings here, but could you please help doing this on a non cloud environment, because if we want to use for enterprise usage, the data is all confidential and they dont like the data to be stored in cloud .. will be really great if you can help us in this regards.

[abhisheksanjaygawade]

Only because of you am I able to build cause

Hi I wonder if it's possible to train it with video.
I'm a blender 3d user and i wonder if i can record myself modeling with blender and use this video to create a model that can do the same work than me ?
