+Packager is a simple yet powerful package manager
+
+## Install a package
+pkgr supports fetching packages with a:
+- path
+- url (http/https)
+- package locator
+
+```shell
+# example with path
+pkgr install ./foxy/snek.pkg
+# example with url
+pkgr install https://example.com/doggo.pkg
+# example with package locator
+pkgr install foo:stable,bar
+```
+
+## Composing a package
+Right now, pkgr does not have a compose/package command. (it's in the works dw!)  
+You can create a package with `pkg.py`!  
+
+```shell
+# Usage: pkg.py <package_toml_path> <output_path> [<directories_to_include> ...]
+# example:
+python pkg.py manifest.toml example.pkg root/ source/ scripts/
+# this will create a package with an archive that look like this:
+# [header+manifest]
+# ...
+# [archive: 
+#   root/
+#   source/
+#   scripts/
+# ]
+```
+
+It's not perfect, but it'll get the job done :)
