Change Grafana source code

Hello, I have the version of Grafana 11.3.1 installed on a Windows system, I want to make some customizations, such as changing some HTML texts, the login page, some logos I want to increase the size, but my question is how can I do this ? For logos, I know that replacing the images in the IMG folder already works, but how can I increase the size of the images, and also change the texts, does Grafana have a source code file?

I don’t understand the link, I know where the Grafana configuration folder is, but I want to know what the file is to change the size of images and texts.

That’s an answer - source code files.

But what would be the specific file to change the login page data, for example? I’ve looked at several files in the folder and haven’t found them.

That’s really wide topic and you need to have daveloper skills (you need to sort also licensing issues).
You may buy Grafana enterprise license, where you can configure custom branding:
