1. Clone
2. Delete the git folder, so you can start tracking in your own repo
3. Run `go get` to install dependencies
4. Copy env_example.json to env.json and fill in the values
4. Copy env_example.toml to env.toml and fill in the values
5. Run `go run main.go` to start the server
6. Rename the occurences of "GoWeb" to your app name
7. Start building your app!
