-==== 1. Download the Project ====+------ 
 +===== How to...  =====
  
-Download the repository seen above and place it in the location of your choosing.  
  
  
-**Tcl Script Format** 
  
-If you are unfamiliar with how to run projects in this new format, see the [[http://www.instructables.com/id/How-to-run-Digilent-Tcl-format-projects/|guide]]  on the usage of the new project format. Please read the short document included within the project folder.+==== 1. Generate the Project ====
  
-==== 2. Load the Vivado Project ====+>1.1) Download the repository linked in the download section and place it in the location of your choosing. 
  
->2.1) Within the project folder there will be two subfolders named "proj" and "src".Go into the proj folder and right click the "create_project" file and select "Properties". Highlight and copy the file's location. FIXME(pictures)+>1.2) Generate the **Abacus** project in the Projects folder by following this guide before continuing: [[vivado:github|How to Generate a Project from Digilent's Github]]
  
->2.2) Open a new Vivado window and enter the letters 'cd' (for change directory) followed by the file location you just copied into the Tcl Console window at the bottom.+==== 2. Build the Project ==== 
 + 
 +>2.1) Click **Generate Bitstream** on the left hand menu towards the bottom. Vivado will run through both Run Synthesis and Run Implementation before it generates the bitstream automatically. 
 > >
->As in the image above, once you have copied there may be a pop-up with a suggested 'proj/'. If you click on this the Tcl Console will automatically flip the slashes in the address from back slashed ( / ) to forward slashes ( \ ). This is a bit mundane but is important since the console will not recognize the address with the backslashes. If it does not automatically correct them, just go in manually and replace each back slash with a forward slash.+>Note: If you want, you can click each step by itself in the order of **Run Synthesis**, **Run Implementation** and then **Generate Bitstream**.
 > >
->Again, as illustrated in the images, type in "source ./" and select the auto-fill suggestion 'create_project.tcl' and hit enter.+>{{:basys3:buildflow.png?600|}}
  
-{{:basys3:gpio_load.png?600|}}+==== 3. Program the Board ====
  
-==== 3. Synthesize, Implement and Generate Bitstream ==== +>3.1) Once you have generated your bit file, Click on the hardware manager and connect to your board by choosing the local server option. 
- +> 
-To complete this step all that you need to do is click **Generate Bitstream** on the left hand menu towards the bottom. Vivado will run through both Run Synthesis and Run Implementation before it generates the bitstream automatically. If you want, you can click each step by itself in the order of **Run Synthesis**, **Run Implementation** and then **Generate Bitstream**. +>{{:basys3:device_connected.png?600|}}

-Once you have generated your bit file, Click on the hardware manager and connect to your board by choosing the local server option. +

-After your board is connected, just click program to load the abacus demo onto your Basys3.+>3.2) Click program to load the abacus demo onto your Basys3.
  
-===== Running the Basys3 Abacus Demo =====+==== 4. Run the Project ====
  
 To run all the features of this demo, all you will need is your programmed Basys3. The abacus can preform 4 arithmatic functions on two 8-bit numbers. Switches 15-8 represent input A. Switches 7-0 represent input B. The abacus works by setting the slide switches to your desired operands and then selecting an operation with the buttons. The result will be displayed on the 7 segment display. On startup, the display will read 0. To run all the features of this demo, all you will need is your programmed Basys3.
