 =====URLs=====
-The GitHub repository for Vircon32 and DevTools Can be found at: [[https://github.com/vircon32/ComputerSoftware/releases]]
+The main Virocon32 site is [[https://www.vircon32.com/|vircon32.com]]
-This site will provide zip files for both and how to install them.
+The list of Releases can be found on the Vircon32 GitHub repository here: [[https://github.com/vircon32/ComputerSoftware/releases|https://github.com/vircon32/ComputerSoftware/releases]]
-=====Build from Source=====
-Install the Emulator and the DevTools outside the Lab46 repository. It is recommended to do this on your Pi and the following steps is for the Pi. Download the following from the GitHub repository linked in previous section
+  *This repository has .zip and .tar.gz files containing all necessary source code
-''<color #00a2e8>Vircon32-Emulator-24.3.2-RaspberryPi4-Raspbian.zip</color>''
+The list of C header files for Vircon32 is here [[https://www.vircon32.com/api.html|https://www.vircon32.com/api.html]]
-''<color #22b14c>Vircon32-DevTools-24.2.4-RaspberryPi4-Raspbian.zip</color>''
+  *Functions specific to Vircon32 are defined here, including video.h
+=====Build from Source=====
-Unzip these files which provide a similar file name with a .DEB file extension
+The aforementioned archive files contain a README detailing the build process.
-''<color #00a2e8>vircon32-emulator_24.3-2_armhf.deb</color>''
-''<color #22b14c>vircon32-devtools_24.2-4_armhf.deb</color>''
-To install these use the following commands:
-<code>
-     sudo dpkg -i vircon32-emulator_24.3.2_armhf.deb
-     sudo apt-get install -f
-     sudo dpkg -i vircon32-devtools_24.2.4_armhf.deb
-</code>
-The base path for the install is ''/opt/Vircon32/Emulator''
-To run the Vircun32 API, change to the emulator directory and run ''./Vircon32''
-There's a hidden task bar near the top of the screen that shows up when your mouse is near that shows multiple actions you can do.
 =====Cartridge build process=====
+All of the following steps can be simplified by using the Make.sh that is already made for us. It's worth looking within the file to see how it operates. To use this file you can type <code> bash Make.sh </code> The <wrap hi> .sh </wrap> represents that it is a shell script file.
 ====compile====
+First we need to compile the C code, which can be done with the following command from the Vircon32 developer tools:
+<code>compile CODE.c -o obj/CODE.asm || abort_build</code>
+Where <wrap hi>CODE</wrap> is the name of your file, which may be preceded with "Tutorial" if you're keeping the same name as the demo file.
 ====assemble====
+Once you've compiled your code successfully, you can use the following Vircon32 tool to assemble the ASM code:
+<code>assemble obj/CODE.asm -o obj/CODE.vbin || abort_build</code>
+Where, again, <wrap hi>CODE</wrap> is whatever you decided to name this project.
 ====image processing====
+To use the images we want with the Vircon32 console/emulator, we have to first use one of the development tools provided to us. This tool is called png2vircon, and if you have it in your path you should be able to use it as such: <code> png2vircon IMAGE.png </code> where IMAGE is the file name of your png.

 ====displaying text====
+Text can be displayed with the set_drawing_point() and print() methods
-A basic way of displaying text would be to set the ( x, y ) coordinates of the starting point, followed by printing your text. Below is the example from the Hello World tutorial.
 <code>
-    // draw our text near the top-left of the screen
+set_drawing_point(0, 0);
-    set_drawing_point( 20, 120 );
+print("Hello World");
-    print( "Hello, World!" );
 </code>
+The print() method draws text using the drawing point as the uppermost left part of the text
 ====processing textures and regions====
+select_texture(int texture_id)
+  *"Sets the selected texture to the given texture ID. All texture functions will apply to that texture from that moment"
+  *Selects a .vtex texture that will be used for other functions (like select_region)
+select_region(int region_id)
+  *"Sets the selected texture region to the given texture ID. All region functions will apply to that region ID from the selected texture"
+  *Selects/creates a region that is used by other functions (like define_region)
+define_region(int min_x, int min_y, int max_x, int max_y, int hotspot_x, int hotspot_y)
+  *Defines the currently selected texture region, as a rectangle within the selected texture. All arguments are given in pixel coordinates within the selected texture
+  *Defines the bounds of the region, used for other function (like draw_region_at
+  *Allows a specific portion of a texture to be used as a sprite
+  *Allows a single texture/.png/.vtex to be used for many sprites/regions
