Following this guide will set up a local Elasticsearch with Kibana and Marvel using Homebrew and Homebrew Cask
If you already have Java installed on your system, skip steps Install Cask and Install Java
If you already have Java and Homebrew installed on your system, skip steps Prerequisites, start at Install Elasticsearch and Kibana after running $ brew update
$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
If you don't have homebrew installed - get homebrew here
Then run: brew install elasticsearch
Update the elasticsearch configuration file in /usr/local/etc/elasticsearch/elasticsearch.yml.

| //To fetch a branch, you simply need to: | |
| git fetch origin | |
| //This will fetch all of the remote branches for you. With the remote branches | |
| //in hand, you now need to check out the branch you are interested in, giving | |
| //you a local working copy: | |
| git checkout -b test origin/test |
