I was trying to upload file larger than 400MB, but I got HTTP500 error.
Configuration was made according to https://www.bookstackapp.com/docs/admin/upload-config/ documentation.

After some digging I found that PHP script memory usage should be increased aswell to increase max file size for uploads.

I think that additional configuration information about this should be included in documentation.
within php.ini

Default is 128M.
Maximum amount of memory a script may consume (128MB)
memory_limit = 128M

By increasing memory limit max file upload size also increases.

Thanks @aarchijs for raising this.

I have now updated the documentation to advise that the memory limit may also need to be changed for larger files.
