+## General description
+
+This application is intended to be ran as a Kron-job in Docker. It should run once every 24 hours and creates a road network,
+which is based on OSM. OSM provides three types of element: nodes, ways and relations. Each element has a lot of meta data,
+as well as tags that describe different features. The map data parser filters most of this data away.
+
+Ways that represent streets are turned into segments and ways that represent buildings or other
+objects are not used. Only the start and end nodes of segments are container within the road network and overlapping segments
+are being split. The road type is defined by the `highway` tag.
+
+Relations in OSM represent turn restrictions. The map builder considers only some of those, due to the complexity of certain
+turn restrictions and the original scope of the project.
+
+## Installation instructions
+
+First, add an access key to the repo in the `settings.xml` of your Maven installation.
+
+```xml
+<servers>
+    <server>
+        <id>protos</id>
+        <configuration>
+            <httpHeaders>
+                <property>
+                    <name>Private-Token</name>
+                    <value>glpat-LUzA2H9fVytwNmmC-6MH</value>
+                </property>
+            </httpHeaders>
+        </configuration>
+    </server>
+</servers>
+```
 
-First install the protobuf compiler with : 
+Run `mvn clean install -U` to get all the dependencies and then run the application as you would in your IDE.
 
-```sh
-sudo apt install protobuf-compiler
-```
+The application writes a `roadnetwork.proto` file when it's done. This can then be used with the routing server or the debug
+tool. Check the respective documentations for further information.
 
-If you want to build the protos from source schema, you should use the command : 
+### Alternatively
 
-```sh
-protoc -I=./mapbuilder/src/main/java/map/builder/protos/ --java_out=./mapbuilder/src/main/java/ ./mapbuilder/src/main/java/map/builder/protos/schema/roadnetwork.proto
-```

+You can also use the Docker image and set it up the container in Docker.
