 ## Setup
 
-Todo
\ No newline at end of file
+### Prerequisite
+
+- A working game, with dongle and card reader emulation. You can use [TAL](https://github.com/BroGamer4256/TaikoArcadeLoader) for these if you haven't.
+
+### Server setup
+
+1. Download the server from release page, extract anywhere
+
+2. Modify hosts, add the following entries:
+
+   ```
+   server.ip      tenporouter.loc
+   server.ip      naominet.jp
+   server.ip      v402-front.mucha-prd.nbgi-amnet.jp
+   server.ip      vsapi.taiko-p.jp
+   ```
+
+   where `server.ip` is your computers ip (or the server's ip)
+
+3. Setup Apache as reverse proxy. Notice the following assumes a windows install, the server also works on Linux, but the guide only covers windows. 
+
+   1. Download [Apache](https://www.apachelounge.com/download/), extract anywhere
+
+   2. Modify conf/httpd.conf:
+
+      ```htaccess
+      # example: c:/Apache24
+      Define SRVROOT "full:/path/to/Apache/folder" 
+      
+      # In loadmodule section, find the following lines and uncomment (remove the # at the beginning), they are by default commented out
+      LoadModule proxy_module modules/mod_proxy.so
+      LoadModule proxy_http_module modules/mod_proxy_http.so
+      LoadModule ssl_module modules/mod_ssl.so
+      LoadModule headers_module modules/mod_headers.so
+      
+      # Scroll down to bottom, find this line and uncomment
+      Include conf/extra/httpd-vhosts.conf
+      ```
+
+   3. Modify conf/extra/httpd-vhosts.conf, add the following
+
+      ```htaccess
+      <VirtualHost *:80>
+          ProxyPreserveHost On
+          ProxyPass / http://127.0.0.1:5000/
+          ProxyPassReverse / http://127.0.0.1:5000/
+          ServerName naominet.jp
+          RequestHeader set "X-Forwarded-Proto" expr=%{REQUEST_SCHEME}
+      </VirtualHost>
+      
+      Listen 10122
+      
+      Listen 54430
+      Listen 54431
+      
+      <VirtualHost *:10122 *:54430 *:54431>
+          ProxyPreserveHost     On
+          ProxyPass             / http://127.0.0.1:5000/
+          ProxyPassReverse      / http://127.0.0.1:5000/
+          SSLEngine             on
+          SSLProtocol           all -SSLv3
+          SSLCertificateFile    certs/localhost.crt
+          SSLCertificateKeyFile certs/localhost.key
+          ServerName            vsapi.taiko-p.jp
+          RequestHeader set "X-Forwarded-Proto" expr=%{REQUEST_SCHEME}
+      </VirtualHost>
+      ```
+
+   4. Modify conf/openssl.cnf, change the start of file to 
+
+      ```
+      #
+      # OpenSSL example configuration file.
+      # This is mostly being used for generation of certificate requests.
+      #
+      
+      # Note that you can include other files from the main configuration
+      # file using the .include directive.
+      #.include filename
+      
+      # This definition stops the following lines choking if HOME isn't
+      # defined.
+      HOME                    = .
+      openssl_conf = default_conf
+      # Extra OBJECT IDENTIFIER info:
+      #oid_file               = $ENV::HOME/.oid
+      oid_section             = new_oids
+      
+      [default_conf]
+      ssl_conf = ssl_sect
+      
+      [ssl_sect]
+      system_default = system_default_sect
+      
+      [system_default_sect]
+      CipherString = DEFAULT@SECLEVEL=1
+      
+      # To use this configuration file with the "-extfile" option of the
+      # "openssl x509" utility, name here the section containing the
+      # X.509v3 extensions to use:
+      # extensions		=
+      # (Alternatively, use a configuration file that has only
+      # X.509v3 extensions in its main [= default] section.)
+      ```
+
+   5. Copy the cert folder from server release to Apache root folder, then click on the localhost.crt file and import it to trusted root store.
+
+      If everything is correct, run bin/httpd.exe, a command prompt will open (and stay open, if it shut down, probably something is not setup correctly)
+
+4. Now run the server, if everything is setup correctly, visit http://localhost:5000, you should be able to see the web ui up and running without errors.
+
+5. Go to game folder, copy the config files (AMConfig.ini and WritableConfig.ini) in the config folder from server release to AMCUS folder and replace the original ones.
+
+6. Open command prompt as admin, navigate to game root folder (where init.ps1 is). Run `regsvr32 .\AMCUS\iauthdll.dll`. It should prompt about success.
+
+7. Run AMCUS/AMAuthd.exe, then run AMCUS/AMUpdater.exe. If the updater run and exits without issue, you are ready to run the game and connect to server.
+
+8. Run the game, it should now connect to the server.
