 ## Project structure
 - `spec` contains the specification for lb packages
+    - `pkgspec.md` contains the specification of lbpkgs, this is only
+      useful for those who plan to contribute to the `lbpkg` command
+      line too for creation of lbpkgs
+    - `buildspec.md` contains the specification for the `lbpkg` build
+      file, which outlines the process of building the package, the
+      `lbpkg` tool will convert this into a `pkgspec.md` compliant
+      package for lblinux.
 - `src` contains the source code for lbpkg command line tool

 ### Info
+Everyone lbpkg should MUST contain a `PKGINFO` file. This file outlines
+the metadata of the package. It uses a key-value format `<key>: <value>`
+(whitespace is ignored!). With multiple values use a comma `,` to denote
+more elements, `<key>: <value1>,<value2>,<value3>`. Below you can find a
+list of all the keys and a description of their values.
+
+pkgtype: Denotes the type of package, there is only two values
+permitted, `group` which denotes a group of packages, this will not have
+a LBMANIFEST but instead provides a list of packages contained within
+the group (see groupcontents option). The other option is `pkg`, which
+denotes a typical package which contains a LBMANIFEST file.
+
+pkgversion: Denotes the version of the package, this should be identical
+to the version of the software the package is distributing.
+
+pkgrelease: The release of the package, similar to how pacman (Arch
+Linux package manager) has pkgrel, pkgrelease denotes a change to the
+package structure itself, instead of the software it is distributing.
+
+depends: A list of packages which this package depends on at runtime.
+
+makedepends: A list of packages which this package requires to be built.
+
+groupcontents: specifies the packages contained within a group, this can
+not be set if pkgtype is set to `pkg`.
