  - Detailed reproduction steps: sometimes I can spot a bug pretty easily, but often it's much more obscure. The more information I have to help reproduce it, the quicker it'll get fixed.

 ## Using
-If you want to depend on CC: Tweaked, we have a maven repo. However, you should be wary that some functionality is only
-exposed by CC:T's API and not vanilla ComputerCraft. If you wish to support all variations of ComputerCraft, I recommend
-using [cc.crzd.me's maven](https://cc.crzd.me/maven/) instead.
+CC: Tweaked is hosted on my maven repo, and so is relatively simple to depend on. You may wish to add a soft (or hard)
+dependency in your `mods.toml` file, with the appropriate version bounds, to ensure that API functionality you depend
+on is present.

+
+This is useful in conjunction with Bundled Cables from the RedPower mod, RedNet
+Cables from the MineFactory Reloaded mod, and colors on Advanced Computers and
+Advanced Monitors.
+
+For the non-American English version just replace @{colors} with @{colours} and
+it will use the other API, colours which is exactly the same, except in British
+English (e.g. @{colors.gray} is spelt @{colours.grey}).
+
+On basic terminals (such as the Computer and Monitor), all the colors are
+converted to grayscale. This means you can still use all 16 colors on the
+screen, but they will appear as the nearest tint of gray. You can check if a
+terminal supports color by using the function @{term.isColor}.
+
+Grayscale colors are calculated by taking the average of the three components,
+i.e. `(red + green + blue) / 3`.
