-Build eos image
+## Build eos image
 
-```
+```bash
 git clone https://github.com/EOSIO/eos.git --recursive
 cd eos
 cp genesis.json Docker 
 docker build -t eosio/eos -f Docker/Dockerfile .
 ```
 
-Start docker
+## Start docker
 
-```
+```bash
 sudo rm -rf /data/store/eos # options 
 sudo mkdir -p /data/store/eos

 ```
 
-Get chain info
+If you get an error after `docker-compose` step, you may have to change directory permissions to your current system user 
 
+```bash
+sudo chown -R SYSTEM_USER /data/store/eos
 ```
+
+## Get chain info
+
+```bash

 ```
 
-Run example contracts
+## Execute eosc commands
 
 You can run the `eosc` commands via `docker exec` command. For example:
+
+Some test commands
+
+```bash
+docker exec docker_eos_1 eosc get info
 ```
-cd /data/store/eos/contracts/exchange
-docker exec docker_eos_1 eosc contract exchange contracts/exchange/exchange.wast contracts/exchange/exchange.abi
 
+```bash
+docker exec docker_eos_1 eosc get account inita
 ```
 
-Done
+Compile sample "exchange" contract to text WASM and upload it
+
+```bash
+docker exec docker_eos_1 eosc set contract exchange contracts/exchange/exchange.wast contracts/exchange/exchange.abi
+```
+
+## Access Shell of Running EOS Container
