Q:

Contao 4.x /install.php returns 404

After successful installation doesn't get the install.php. 

www.mydomain.com/web/contao/install.php

returns 404 error.Also I need a proper documentation for creating a custom module in contao.Someone please help me.

A:

First of all you need to set the DocumentRoot in your web server of your domain for your Contao installation to the /web folder of your Contao installation.
The route for the Contao Install Tool is example.org/contao/install in Contao 4 (without .php).
Documentation can be found here: https://docs.contao.org/
You can still create modules in Contao 4 the same way as in Contao 3, i.e. as an extension within in /system/modules. If you want to create a Contao 4 bundle, look at the documentation and look for other tutorials on the web and seek help in the community forums if necessary.
