 ## Server instruction list
-1.  git clone --recursive https://github.com/SamuelHassine/zotero-prime.git
-2.  cd zotero-prime
-3.  find /mnt/zotero/zotero-prime -type f -exec sed -i 's/8080/8084/g' {} +
-4.  cd docker
-5.  docker-compose up -d
-6.  ./bin/init.sh
+Download of the sourcefiles for the zotero server via git to /mnt/zotero/.
+`git clone --recursive https://github.com/SamuelHassine/zotero-prime.git`
+As there already is a service running on port 8080, we need to replace every occurence of 8080 in the source files by 8084.
+`cd zotero-prime && find /mnt/zotero/zotero-prime -type f -exec sed -i 's/8080/8084/g' {} +`
+Creating the different containers needed for the server.
+`cd docker && docker-compose up -d`
+Initialize the databases.
+`./bin/init.sh`
+To prevent errors later on we need to increase the virtual memory areas count as discussed in [this issue](https://github.com/docker-library/elasticsearch/issues/111).
+`sysctl -w vm.max_map_count=262144`
+I did also set the variable permanently in the /etc/sysctl.conf config file.

 ## Client instruction list
 1.  find /mnt/zotero/zotero-client -type f -exec sed -i 's/localhost:8081/zam10128.zam.kfa-juelich.de:8081/g' {} +
