+# SNAG Package Manager
+
+## Useful Subcommands
+`install`/`inst` - install the specified package(s) (default)
+`remove`         - uninstall the specified package(s)
+`upgrade/'up`    - upgrade the package database
+`find`/`search`  - list packages whose metadata matches specified search string
+`info`/`desc`    - describe the metadata of the specified package(s)
+
+`files`          - list the installed files of the specified package(s)
+`log`            - open your pager to the build log of the specified package
+`reason`         - list why this package is installed (manually installed, as a dependency, from a group)
+
+## Terminology
+"Package Database"             - the directory containing package descriptions
+"Install Database"             - the directory containing information on installed package
+"Package Description"          - the directory and script containing build instructions for a package
+"Package Info/Metadata"        - the metadata encoded in the package description
+"Package Attribute"            - a single key value property of the package info
+
+## Package Format
+Each package has a directory in the package database, named by its `id`.
+Inside each package directory is the description script named `{id}.sh`
+The description script should have functions for `configure`, `build`, and `install`
+The description script should define variables for attributes with the name `pkg_{attr}`
+> We're still deciding if we want the metadata to be split from the instruction in separate file(s).
+
+Packages have the following attributes:
+`id` - the identifier name of the package. everything uses this
+`name` - the display name of package
+`desc` - the short description of the package
