+# Introduction
+This tutorial describes how to set up [Wiki.js](https://js.wiki/) as a free wiki software using MySQL as the database backend.
+
+The latest version of Wiki.js that does not yet require a PostgreSQL database backend is 2.x and we can install this using a MySQL database backend that is available in all netcup Webhosting packages.
+
+netcup is already offering Node.js support beginning with the Webhosting 4000 but a better Webhosting 8000 package also works.
+
+The reading time of this tutorial is about five minutes. The implementation will take approximately 45 minutes.
+
+The most important requirements for following this tutorial are a basic understanding of SSH, the Unix command line, and a netcup webhosting package with Node.js support.
+
+The tutorial uses the example sub-domain `wikijs.example.com`. This hostname needs to be replaced with the name of your own domain or subdomain when you perform the steps described in this tutorial.
+
+# Requirements
+The installation can be performed on any VPS but this tutorial focuses on a default webhosting setup:
+
+* Webhosting 4000 or better with Node.js support
+* a (sub) domain
+
+# Step 1 - Add the subdomain and get the document root
+Adding a subdomain is easy using the WCP [Add Subdomain] button in the webhosting interface "Websites & Domains".
+
+![WCP (Plesk) adding a subdomain](images/netcup_wcp_add_subdomain_wikijs_example_com_en-US.png)
+
+We use the following subdomain: `wikijs.example.com`
+
+Note down the "Document root" under "Hosting Settings" that we will need later during the configuration.
+
+In this tutorial we use the default document root suggested by WCP when adding the subdomain: 
+
+`/wikijs.example.com/httpdocs`
+
+
+# Step 2 - Secure domain / subdomain with SSL certificate
+In the "SSL/TLS Certificates" settings of the new subdomain, you can add a recommended SSL certificate with Let's Encrypt.
+
+![WCP (Plesk) setup LE SSL certificate](images/netcup_wcp_sslit_lets_encrypt_wikijs_example_com_en-US.png)
+
+
+# Step 3 - Create MySQL database
+Now we create a new MySQL database for WikiJS usage using the WCP [Add Database] button in the webhosting interface "Databases" navigation entry.
+
+![WCP (Plesk) Databases - Add Database](images/netcup_wcp_Databases_Add_Database_en-US.png)
+
+Create a new database `k123456_wikijs` with the database user `k123456_wikijs_db_user` and password `Secret123` and note down the IP address of the webhosting MySQL server and the other values for the database.
+
+The following values should be written down:
+```
+Database name: k123456_wikijs 
+Database server: 10.11.12.13 (the port is the default MySQL port 3306)
+Database user name: k123456_wikijs_db_user 
+Password: Secret123 
+```
+
+
+# Step 4 - Download WikiJS 2.x package via SSH and extract the archive
+Download the WikiJS release from the download page: [https://js.wiki/get-started]
+
+We use the latest stable release '2.x' tar.gz package for this tutorial and we connect to the webhosting instance using SSH.
+
+Connect to your webhosting instance via SSH using the details in the "Web Hosting Access" section of the subdomain.
+
+Navigate to the document root:
+`cd wikijs.example.com/httpdocs/`
+
+Delete the favicon.ico and index.html which were created during Step 1:
+`rm favicon.ico index.html`
+
+Navigate back to the domain root:
+`cd ..`
+
+Download the complete package in tar.gz format:
+`wget https://github.com/Requarks/wiki/releases/latest/download/wiki-js.tar.gz`
+
+Extract the tar.gz package:
+`tar xzvfs wiki-js.tar.gz`
+
+Symlink the Wiki.JS server Node.js file to app.js:
+`ln -s server/index.js app.js`
+
+
+## Step 4.1 - Configure the database connection in config.yml
+Copy the sample configuration:
+`cp config.sample.yml config.yml`
+
+Then change the database connection settings using nano editor:
+`nano config.yml`
+
+The following values should be set in the Database section:
+```
+db:
+  type: mysql
+
+  # MySQL netcup webhosting details here from step 3:
+  host: 10.11.12.13
+  port: 3306
+  user: k123456_wikijs_db_user
+  pass: Secret123
+  db: k123456_wikijs
+  ssl: false
+```
+
+
+# Step 5 - Setup the Node.js Plesk support
+Activate the Node.js support in Plesk for the domain / subdomain using the [Node.js] button in WCP.
+
+![WCP (Plesk) activating Node.js support](images/netcup_wcp_activate_Node_js_support_wikijs_example_com_en-US.png)
+
+Change the Node.js Version to an even version like e.g. `20.11.1` and select [Enable Node.js]
+
+Run npm command in the tab "Run Node.js commands": 
+`config set legacy-peer-deps true`
+
+![WCP (Plesk) NPM install](images/netcup_wcp_activate_Node_js_support_run_command_en-US.png)
+
+Run [+ NPM install]
+
+![WCP (Plesk) NPM install](images/netcup_wcp_activate_Node_js_support_NPM_install_en-US.png)
+
+
+# Step 6 - Setup the WikiJS installation using the web installer
+Open the domain / subdomain in a web browser of your choice: https://wikijs.example.com
+
+Fill in the administrator e-mail, password and website URL without trailing slashes and confirm.
+
+You will be redirected to the login page of the installed WikiJS installation and login is possible with the previously defined administrator e-mail and password.

+
+
+# Conclusion
+The Wiki.js instance can now be used. It is recommended to perform some tests before productive use.
+
+If all tests are positive switch the Application Mode in the Node.js WCP configuration from development to production.
