-# gettingMean-2
+# gettingMean-2
+# Getting MEAN Second Edition application code
+
+This is the code for the sample 'Loc8r' application that is built through the course of the book Getting MEAN Second Edition.
+
+Getting MEAN Second Edition is published by Manning, and teaches readers how to develop web applications end-to-end using the MEAN stack with Node 11 and Angular 7. It is currently in early access through the MEAP program, with new chapters being released regularly.
+
+> Note: if you have the First Edition of the book using Node 4 and Angular 1 you need the [First Edition code](https://github.com/simonholmes/getting-MEAN/) instead.
+
+## The application at various stages
+
+There will be named branches for the various states of the code throughout the book:
+
+* `master` **Chapter 3 start**: A blank Express 4.16.3 project
+* `chapter-03` **Chapter 3 end**: Creating and setting up a MEAN project
+* `chapter-04-views` **Chapter 4 mid-point**: The data is hard coded into views
+* `chapter-04` **Chapter 4 end**: Building a static site with Node.js and Express
+* `chapter-05` **Chapter 5**: Building a data model with MongoDB and Mongoose
+* `chapter-06` **Chapter 6**: Writing a REST API: Exposing your MongoDB database to the application
+* `chapter-07` **Chapter 7**: Consuming a REST API: Using an API from inside Express
+* `chapter-08` **Chapter 8**: Creating an Angular application with TypeScript
+* `chapter-09` **Chapter 9**: Building a Single Page Application with Angular
+* `chapter-10` **Chapter 10**: Building a Single Page Application with Angular: The next level
+* `chapter-11` **Chapter 11**: Authenticating users, managing sessions and securing APIs
+* `chapter-12` **Chapter 12**: Using an authentication API in Angular applications
+
+## Get the code to run on your machine
+
+Pre-requisites:
+
+* Git installed
+* A command line interface capable of running Git commands
+* Node v11 installed
+
+To get the code for a specific branch:
+
+`$ git clone -b branch-name https://github.com/cliveharber/gettingMean-2.git`
+
+Then change into the folder the git clone command will create:
+
+`$ cd getting-MEAN-2`
+
+And finally install the dependencies:
+
+`npm install`
+
+## Getting the code via Docker
+
+Pre-requisites:
+
+* Docker
+
+To get the code for a specific branch:
+
+`$ git clone -b branch-name https://github.com/cliveharber/gettingMean-2.git`
+
+Then change into the folder the git clone command will create:
+
+`$ cd getting-MEAN-2`
+
+And finally run the docker containers
+
+`make build`
+
+To remove the containers when complete
+
+`make destroy`
