-## Test project generation and docker-compose build Vagrant usage
-
-Testing with [vagrant](https://www.vagrantup.com/docs) works like this:
-What vagrant does:
-
-Starts a vm for test on docker swarm:
-    - configures a GeoNode project from template every time from your working directory (so you can develop directly on geonode-project).
-    - exposes service on localhost port 8888
-    - rebuilds everytime everything with cache [1] to avoid banning from docker hub with no login.
-    - starts, reboots to check if docker services come up correctly after reboot.
-
-```bash
-vagrant plugin install vagrant-reload
-#test things for docker-compose
-vagrant up
-# check services are up upon reboot
-vagrant ssh geonode-compose -c 'docker ps'
-```
-
-Test geonode on [http://localhost:8888/](http://localhost:8888/)
-
-To clean up things and delete the vagrant box:
-
-```bash
-vagrant destroy -f
-```
-
-## Test project generation and Docker swarm build on vagrant
-
-What vagrant does:
-
-Starts a vm for test on docker swarm:
-    - configures a GeoNode project from template every time from your working directory (so you can develop directly on geonode-project).
-    - exposes service on localhost port 8888
-    - rebuilds everytime everything with cache [1] to avoid banning from docker hub with no login.
-    - starts, reboots to check if docker services come up correctly after reboot.
-
-To test on a docker swarm enable vagrant box:
-
-```bash
-vagrant up
-VAGRANT_VAGRANTFILE=Vagrantfile.stack vagrant up
-# check services are up upon reboot
-VAGRANT_VAGRANTFILE=Vagrantfile.stack vagrant ssh geonode-compose -c 'docker service ls'
-```
-
-Test geonode on [http://localhost:8888/](http://localhost:8888/)
-Again, to clean up things and delete the vagrant box:
-
-```bash
-VAGRANT_VAGRANTFILE=Vagrantfile.stack vagrant destroy -f
-```
-
-for direct deveolpment on geonode-project after first `vagrant up` to rebuild after changes to project, you can do `vagrant reload` like this:
-
-```bash
-vagrant up
-```
-
-What vagrant does (swarm or comnpose cases):
-
-Starts a vm for test on plain docker service with docker-compose:
-    - configures a GeoNode project from template every time from your working directory (so you can develop directly on geonode-project).
-    - rebuilds everytime everything with cache [1] to avoid banning from docker hub with no login.
-    - starts, reboots.
-
-[1] to achieve `docker-compose build --no-cache` just destroy vagrant boxes `vagrant destroy -f`
