+## Docker dev setup
 
-<!-- Google Analytics --> 
+Work with docker 1.10.3 and docker-compose 1.6.2
+
+- initalize your environment:
+
+```
+cp docker-compose.yml.example docker-compose.yml
+cp docker/env.example docker/env
+cp pypolo/local_settings.py.example pypolo/local_settings.py
+```
+
+1. Add your POLONIEX_API_KEY and POLONIEX_API_SECRET to docker/env (its gitignored, dont worry)
+2. Build Docker image (compiling stuff for scipy and numpy takes time): `docker-compose build` or pull the images from Docker Hub: `docker-compose pull`
+4. Run the containers: `docker-compose up`
+5. Get shell: `docker exec -it pytrader_web_1 /bin/bash`
+6. Place sql seed in this repo dir as `prices.psql`
+7. in Django container 
+
+```
+cd /root/pytrader
+export PGPASSWORD=$POSTGRES_PASSWORD
+psql -h db -U trader trader < prices.psql
+```
+wait for the psql load to end
+
+8. restart setup: (in the host): `docker-compose kill && docker-compose up -d`
+9. Visit http://localhost:8000/admin and log in as `trader:trader`
