Is there a kind of 'dummy' set of instructions?
I have NO clue whatsoever when it comes to web development, however I have an idea I'd like to try, which requires a server somewhere

and something to run on the mobile device. (Sorry I cannot give details, that's commercial. If you want to compare it with anything, assume it's a Dungeons and Dragons spellbook that is managed online, but can be viewed offline, it's as close as it gets...)
OptionsI have two options / see two stages:
a. either web only (all intelligence on the server side) which limits the deployment to online only, but that might be acceptable, or...
b. (partially) operational even when offline, which requires some code on the user's device, but this is for later worrying
I'd probably start with a, but want to move to b in the long run.
I've been browsing the SpiderBasic website a bit, but some things aren't very clear to me. (I might have just missed the 'survival guide' equivalent

)
Questions1. Is there a 'SpiderBasic for Dummies'?
2. What do I need to run things 'at home'? I assume I need to set up some webserver in a VM or similar to simulate real world behavior (though I could simply opt to run a second 'instance' on the actual server) and SpiderBasic. Anything else I need?
3. I suppose the hosting party must offer me some things... For example, I need to store that database somewhere on the server side, so the hosting party must support a database, I suppose? (The hoster I am considering is supporting MariaDB, kind of MySQL.)
4. Now here's the kicker. Everything above is on the SpiderBasic / web side. But I plan to run some 'raw' PureBasic code, at first on a test machine from home, but I'll probably switch to a dedicated server if things work and are commercially viable. So can I access that (remote) MariaDB with PureBasic?
Here's an example of the setup:
mypc + PureBasic <-- internet --> MariaDB on hoster <-- internet --> browser on mobile
Then, one day, I'd like to also support this:
mypc + PureBasic <-- internet --> MariaDB on hoster <-- internet --> limited data + app on on mobile
Why and why now?Well, I just lost my regular job, and will do some consultancy over the next year. Getting a regular job as a 50+ guy is hard, so why not start to pursue some old ideas I never finished developing...
Part of the issue is that data in that database is processed 'in batches' which will allow quite a bit of off-line processing, compute, and me

tweaking the algorithms until it all works properly and is ready for prime time.
I know there must be better ways to make some money, but at least this way there's a bit of fun still in there

I think I'll be able to make a second income with the concept, but it isn't big enough to start hiring people, set up a big company etcetera.
So, assume I'm out of my mind, and assume I'm not (yet) about to hire a web expert... how would I start?
SpiderBasic... though I am a bit worried about the viability of SpiderBasic, it's what I am most familar with...
Does anyone use that forum? I tried to register, but never receive the registration confirmation, so cannot even ask questions over there...
