 # Zombie
 
+## How to run application
+
+```bash
+docker-compose run app
+```
+
+Or if you have `Go` v1.13 installed locally, then run
+
+```bash
+go run cmd/main.go
+```
+
+## How to run tests
+
+```bash
+docker-compose run app go test ./... -cover
+```
+
+## Where to start to read the code
+
+Please read the code from the entry point `cmd/main.go`
+
+## Assumptions
+
+* All the input data is valid
+
+
+## Highlights
+
+* Used `TableDrivenTests`
+* Used `interface` and `map` to model the `command` part to avoid `if else` checks
+* Built a `First-In-First-Out` structure `nextZombie` in `application` to represent the next zombie to run.     
+* Had `docker compose` built in, you don't need to have Go installed locally. One command to bring up the whole application.
