1  ### Installation
 2  
 3  First make sure you have installed Embark, preferably using NVM.
 4  See install instructions
 5  
 6  ### Create demo app
 7  
 8  <code>`$ embark demo`
 9  `$ cd embark_demo`</code>
10  
11  ### Start a blockchain node or let Embark start it for you
12  
13  Note: starting in Embark 3.1, the command `embark run` will
14  automatically start a blockchain node if one isn’t already running. You
15  may, therefore, skip this step.
16  
17  You can run a REAL ethereum node for development purposes:
18  
19  `$ embark blockchain`
20  
21  Alternatively, to use an ethereum rpc simulator simply run:
22  
23  `$ embark simulator`
24  
25  By default Embark blockchain will mine a minimum amount of ether and
26  will only mine when new transactions come in.
27  
28  If you want, you can skip this step, as `embark
29  run`, `build` and `upload` now all start a blockchain node in a
30  separate process if there is not one already started using the same
31  configurations.
32  
33  ### Start Embark
34  
35  Then, in another command line:
36  
37  `$ embark run`
38  
39  This will open up the embark Dashboard
40  
41  The dashboard will tell you the state of your contracts, the environment
42  you are using, and what Embark is doing at the moment.
43  
44  **available services**
45  
46  Available Services will display the services available to your dapp in
47  green. If a service is down, then it will be displayed in red.
48  
49  **logs and console**
50  
51  There is a console at the bottom which can be used to interact with
52  contracts or with Embark itself. Type `help` to see a list of available
53  commands. More commands will be added with each version of Embark.
54  
55  Embark will then compile & deploy the contracts, update their JS
56  bindings and deploy your DApp to a local server
57  at [<http://localhost:8000>](http://localhost:8000/)
58  
59  > **without the dashboard**
60  
61  Note that if you update your code, it will automatically be re-deployed,
62  contracts included. There is no need to restart embark, refreshing the
63  page on the browser will do.
