Hello! So you want to make a css bhop server for you and your friends, fear not! This tutorial will help you with everything you need to make an **epic** bhop server.
Lets get started:
First, you're gonna want to install steamCMD from the valve developer forums https://developer.valvesoftware.com/wiki/SteamCMD. You should see a small link to a steamcmd.zip folder, click it and wait for it to download. 
Extract steamCMD to somewhere where you will remember about it and you're done!
Installing the server:
Now, you need to set up the server! Go inside your steamCMD folder and find steamcmd.exe. Click it and you will see a command prompt appear. The first thing you're going to want to do is to enter:
login anonymous
Next, when you have connected to steam public, you need to enter:
app_update 232330 validate
It should take a few minutes to install and validate, if it does, then you have officially installed the dedicated server!
Where's the bhop?
Now we have to set up the timer, tickrate enabler, and maps!
- Maps: https://gamebanana.com/maps/cats/2976
- sourcemod: https://www.sourcemod.net/downloads.php?branch=stable
- metamod: https://www.metamodsource.net/downloads.php?branch=stable
- tickrate enabler: https://github.com/daemon32/tickrate_enabler/releases/tag/0.5-100tick
- bhoptimer: https://timer.shav.it/ (follow instructions)
Once you have downloaded all of that stuff, put the sourcemod and metamod in your counter strike source dedicated server addons folder.

Once you have both sourcemod and metamod installed, put all your plugins in the plugins folder in sourcemod.

Once you have all the plugins in that folder (extract only the .sp files to plugins!!!) you are ready to re-run your server.
I have a handy run.bat if you want to put this in the root of the counter strike source dedicated server folder. https://pastebin.com/90BPv1PV (you don't need the -tickrate 100)
Now try to open srcds.exe gui, start the server, copy the ip to your dev console like this
connect [ip]
And if your server looks something like this:

You did it! Now invite your friends and have fun bhopping :)
