+Welcome to Byte Academy
-=======
+=======================
+
+We've put together this program to get you all on the same footing before entering. You will be learning some basic git, Unix, JavaScript, and Python.  
+Our goal is for you hit the ground running when you come to campus.
+
+The resources will build upon each other to whatever extent they can.  
+A lot of it is horizontal to other skills. So, if you are stuck on something, feel free to move on and come back to it later.
+
+## Step 1
 
 Make a [GitHub](https://github.com/) account.
 
-#### Git and Unix
+Pick a text editor to use. We recommend [Sublime](http://www.sublimetext.com/) or [Atom](https://atom.io/).
 
-[Command Line Crash Course](http://cli.learncodethehardway.org/book/)
+Make sure [Python 3.4.2](https://wiki.python.org/moin/BeginnersGuide/Download) and [Node](http://nodejs.org/download/) are installed on your computer
 
-[Try git](try.github.io)
+## Step 2
 
-[Git Immersion](http://gitimmersion.com/)
+Do these tutorials:  
+* [Command Line Crash Course](http://cli.learncodethehardway.org/book/)
+* [Try git](try.github.io)
+* [Git Immersion](http://gitimmersion.com/)
+* [Code Academy HTML/CSS](http://www.codecademy.com/en/tracks/web).
+
+## Step 3
+
+Work through the practice problems provided. We recommend starting with front end, moving to JS, and finishing with Python.
+
+Here are some resources to help you on assignments, as well has good reads.

+Regular Expressions
+===================
+
+Regular Expressions (regex for short) are a way to represent patterns in strings. They aren't as bad as people make them out to be. When used on the right problem, they are a great solution.
+
+Go to [Rubular](http://rubular.com/). We're going to sandbox inside it a bit to get acquainted with regex syntax. At the bottom of the page is a regex cheat sheet.  
+Note: Depending on the language, you may have to escape certain characters. For example, instead of `a{3}`, you may have to type `a\{3\}`.  
+Also, be careful with periods (`.`). A period means any character in regex, so you have to escape it if you want to pattern match a period.
+
+Here are some examples of regex and matching string patterns:  
+* `a{3}` => `aaa`
+* `a{3,}` => `aaaaaaaa`
+* `[a-z]` => any lowercase letter
+* `[A-Z]{4,6}` => between 4 and 6 uppercase letters, ex. `FASDV`
+* `.` => any character
+* `\w\.` => `_.`
+* `hello\d?` => `hello` or `hello5`
+* `[a-nO-Z]*` => abcOZZ
+
+Make a regex to match each of these strings:  
+* match 'byte academy' 3 different ways
+* an 8 character password, do not allow non word characters
+* an 8 character password that has at least 1 number and 1 capital letter
+
+
+* byteacademy@example.com
+* byte.academy@example.com
+* byteacademy22@example.co.uk  
+See if you can get all three with 1 regex, but not invalid emails (not having an @, etc...)
