 # SIKWEB 2.0
 
-## Installation
+## Installation with docker
+
+### installing docker
+
+install docker and docker-compose. On ubuntu this can be done with
+
+```BASH
+sudo apt-get install docker docker-compose
+```
+
+### Configuring db-image
+
+```BASH
+sudo docker-compose up db
+# then configure following with another shell window
+sudo docker exec -ti <image_name> bash  # image name can be found with sudo docker ps (propably web20_db_1)
+mysql -u root -p # then enter root password which is in docker-compose.yml
+
+```
+```SQL
+CREATE USER 'sik'@'%' IDENTIFIED BY 'password123';
+CREATE DATABASE sik DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
+GRANT ALL PRIVILEGES ON sik.* TO 'sik'@'%';
+```
+Then ctrl-d away from docker bash shell and shutdown db image with ctrl-c
+
+### Configuring web-image
+
+1. Fix your settings.py to use 'db' as host and correct user and password (configured above)
+2. run following commands
+```BASH
+
+sudo docker-compose run web python manage.py migrate 
+sudo docker-compose run web python manage.py makemigrations infoscreen members
+sudo docker-compose run web python manage.py migrate 
+sudo docker-compose run web python manage.py createsuperuser 
+```
+
+### starting dev unit
+
+```
+sudo docker-compose up
+```
+
+now you should have dev environment running on localhost:8000
+
+NOTE: as your working dir (web2.0) is mounted by images changes will be reflected immediately. no rebuilding needed. migrations and makemigrations must still be run separately though. see examples above
