+# build file reference
+
+Feel free to take a peek at the `aptpkg-pkgs` repository.
+
+The `build` file is a shell(?) file loaded in by `aptpkg` and should be located
+in its own folder which is named the program.
+
+The first line should be a comment: `# Maintainer: Name or User Name <email@example.org>`
+
+There are currently two types of things aptpkg can process:
+
+1. `type=deb`: Debian packages which are simply downloaded from the URL and
+   checked
+2. `type=file`: Get (a) file(s), check, and execute the `steps` function
+
+This should be defined after `name`, `version`, and `rev` - which is only useful
+when `type=file` and should be set to zero after each version update.
+
+`url` should contain the upstream application's source code/ homepage, and
+`description` should be similar to what has been provided by them.
+
+`source` contains the URL to download and `sha512sums` contains the output to be verified after.
+
+In the `steps` function (for `type=file`), you can use the following variables and functions:
+
+- `$builddir`
+- `cin-bin` to `install` a binary
+- `cin-file` to `install` a file
+
+You can also place maintenance files along `build`: `preinst`, `postinst`, `prerm`, and `postrm`.
