 - VIAaaS receives a the session hash from instance and then the browser validates it to Mojang.
 
 ## Setting up server instance
-Download: [GitHub Actions](https://github.com/ViaVersion/VIAaaS/actions) (needs to be logged into GitHub) or [JitPack](https://jitpack.io/com/github/viaversion/viaaas/master-SNAPSHOT/viaaas-master-SNAPSHOT-all.jar)

 How to start VIAaaS server:
+
 ```sh
 java -jar VIAaaS-all.jar
 ```
+
 - Requires Java 11
 - Default Minecraft: ```via.localhost``` with port 25565
 - Default HTTPS: ```https://localhost:25543/```
 - Default WS URL: ```wss://localhost:25543/ws```
 
 ### How to create a public server
-- You need a domain wildcarding to VIAaaS instance, like ``*.example.com -> 192.168.123.123``. You can use [DuckDNS](https://duckdns.org/) DDNS service.

 ## CORS Proxy
+
 - For less chance of Mojang seeing the login as suspect, you (the player) should set up a CORS proxy on your machine.
 - Note the ending slash in cors-anywhere address

 Setting up [cors-anywhere](https://www.npmjs.com/package/cors-anywhere) on local machine:
+
 ```sh
 git clone https://github.com/Rob--W/cors-anywhere
 cd cors-anywhere
 npm install
 node server.js

 - ```server.example.net.v_1_8.via.example.com```

 ## WARNING
+
 - VIAaaS may trigger anti-cheats, due to block, item, movement and other differences between versions. USE AT OWN RISK
 - Take care of browser local storage. Check for XSS vulnerabilities on your domain.
 - Check the security of CORS proxy, it will intermediate Mojang API calls.
 - Mojang may lock your account when API is called from a suspect IP address
 
 ## FAQ
+
 ### Accounts
+
 My Microsoft account <18 years old is not able to log in, it's giving XSTS error:
+
 - Add your account to a family (see https://wiki.vg/Microsoft_Authentication_Scheme#Authenticate_with_XSTS)
 
 Why a online webpage for online mode?:
-- It's easier to maintain in that way, because providing login via chat requires encoding and decoding more packets which change through versions.

 ### Connection
+
 How to use IPv6?:
+

 I'm getting a DNS error/"Unknown host" while connecting to (...).localhost
+
 - Try configuring via-127-0-0-1.nip.io as hostname suffix
 
 How to use with Geyser?
+
 - Currently you need to set the parameters (at least the hostname) in Geyser's `address` field:
   ```yml
   remote:
     # The IP address of the remote (Java Edition) server
     address: 2b2t.org._v1_12_2.via.localhost
   ```
-- If you are using a public GeyserConnect instance: connect to a publicly available VIAaaS instance, like ```mc.example.com.via.example.net``` as a Java Edition server.
+- If you are using a public GeyserConnect instance: connect to a publicly available VIAaaS instance,
+  like ```mc.example.com.via.example.net``` as a Java Edition server.
 
 Can I use it to connect to .onion Minecraft hidden servers?
-- You can use .onion addresses if the instance is proxying the backend connections to TOR.
+
-  Note that VIAaaS may log your requests.
