+# Ötzi
 
-# Oetzi Words
+This is a web-based typing game.
 
-### Requirements
+## Backend
 
-- Mysql
-- Tomcat 8.5
-- Java 8
-- Maven
-- NodeJS with Npm or Yarn
+The backend is a `fastify` webserver exposing some APIs.
 
-*Tested with tomacat 8.5.72 NodeJs v14.18.0 Java 1.8.0_241*
+To spin it up for development,
 
-### Getting Started
+```bash
+cd backend
+npm install
+npm exec knex migrate:latest
+npm exec knex seed:run
+PORT=8080 npm run watch
+```
 
-Setup your mysql server and load the sql structure dump with :
+The webserver will be abailable at `http://localhost:8080`.
 
+## Frontend
 
-    mysql -u a_valid_user -p < oetzi_words.sql  
+The frontend is a `phaser` webapp built `parcel`.
 
-Setup Apache Tomcat server with:
+To spin it up for development,
 
+```bash
+cd frontend
+npm install
+npm run start
+```
 
-    curl -LO https://archive.apache.org/dist/tomcat/tomcat-8/v8.5.72/bin/apache-tomcat-8.5.72.tar.gz 
-    tar -xvf apache-tomcat-8.5.72.tar.gz
+Also, remember to
 
+    Change line 63/64 of main.js file in src/js folder by switching the comment.
+    This operation permits the ui to call the backend at `http://localhost:8080/oetzi_words/` instead of to the relative path.
 
-### Run Release
-
-Download relase from github and copy `OetziWords.war` in the webapps folder of your apache tomcat installation.
-Run the server with:
-
-    apache-tomcat-8.5.72/bin/startup.sh
-
-Wait ~20 secs and shutdown th server with
-
-    apache-tomcat-8.5.72/bin/shutdown.sh
-
-Now edit the `config.prop` in `apache-tomcat-8.5.72/webapps/OetziWords/WEB-INF` and write the correct parameters for your installation db host, db user, db password and and path to the image folder. Save the file and restart the server. Done.
-
-Go to `http://localhost:8080/OetziWords/`
-
-#### Attention !!! The mysql server must be started before of the  tomcat server
-
-### Make a release from code
-
-Clone this repo with
-
-    git clone https://github.com/commul/oetzi.git
-
-go to oezti folder `cd oetzi` and make the `war` package with
-
-    mvn package
-
-You will find the war file in the target folder
-
-### Working on the game UI on a separete server
-
-First you need to configure your tomcat in order to accept cross origin connection
-
-Edit the web.xml file in the `apache-tomcat-8.5.72/conf` and add the cors filter adding the lines to the file before the Default session configuration section
-
-    <filter>
-	    <filter-name>CorsFilter</filter-name>
-	    <filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
-	    <init-param>
-		    <param-name>cors.allowed.origins</param-name>
-		    <param-value>*</param-value>
-	    </init-param>
-    </filter>
-    <filter-mapping>
-	    <filter-name>CorsFilter</filter-name>
-	    <url-pattern>/*</url-pattern>
-    </filter-mapping>
-
-Restart your tomcat server
-
-
-Got to the `oetzi_game` folder in the repository repository clone
-and install javascript dependencies with
-
-`yarn install` or `npm install`
-
-Change line 63/64 of main.js file in src/js folder by switching the comment.
-This operation permits the ui to call the backend at `http://localhost:8080/oetzi_words/` instead of to the relative path.
-
-Run the game ui with
-
-`yarn run start` or `npm run start`
-
-Now the game runs at `http://localhost:1234`
-
-### Update the webapp ui
-
-If you want to update the game ui in the tomcat backend switch again the comment on line 63/64 and run
-
-`yarn run deploy` or `npm run deploy`
-
-Make new web archive with `mvn packge` in the root folder of the repository and copy the new `war` file in the webapps folder of tomcat, wait the refresh the url `http://localhost:8080/OetziWords/`
-
-### Repository content
-- oetzi_game folder (game ui code)
