+>If you are running Cadence on top of [Mysql](MYSQL_SETUP.md) or [Postgres](POSTGRES_SETUP.md), you can follow the instructions to run the SQL DB and then run:
+
 Now you can setup the database schema
 ```bash
 make install-schema
+
+# If you use SQL DB, then run:
+make install-schema-mysql OR make install-schema-postgres
 ```
 
 Then you will be able to run a basic local Cadence server for development:
 ```bash
 ./cadence-server start
+
+# If you use SQL DB, then run:
+./cadence-server --zone <mysql/postgres> start
 ```
+
 You can run some workflow [samples](https://github.com/uber-common/cadence-samples) to test the development server.
 
 > This basic local server doesn't have some features like advanced visibility, archival, which require more dependency than Cassandra/Database and setup.

+# Setup local MySQL with Docker
+This document describes how to install MySQL 5.7 locally with Docker.
+
+>Note: Install the docker on your machine before installing the MySQL.
+* Make sure any MySQL containers are terminated and removed
+```
+docker ps -a
+docker kill <container_id> && docker rm <container_id> # remove any MySQL containers.
+```
+* Fetch docker image (version 5.7 is what Travis runs so its what you will want locally)
+```
+docker pull mysql/mysql-server:5.7
+```
+* Run docker container (note the port mapping so that 3306 is exposed locally)
+```
+docker run -p 3306:3306 --name=mysql1 -d mysql/mysql-server:5.7
+```
+* When docker starts up the root MySQL user will have an auto generated password. You need to get that password to log into the container
+```
+docker logs mysql1 2>&1 | grep GENERATED
+# The result looks like: [Entrypoint] GENERATED ROOT PASSWORD: iHqEvRYm6UP#YN$es;YnV3m(oJ
+```
+* Log into the container (when prompted for password use the password gotten from last step).
+```
+docker exec -it mysql1 mysql -uroot -p
+```
+* Before any SQL operations can be performed you must reset the root user's password (use anything you like in replace of root_password).
+```
+SET PASSWORD = PASSWORD('root_password');
+```
+* Now create the user that local MySQL tests will use. Also grant all privileges to user.
+```
+CREATE USER 'uber'@'%' IDENTIFIED BY 'uber';
+GRANT ALL PRIVILEGES ON *.* TO 'uber'@'%';
+```
