 Usage
 ========
 
-To use packetary in a project::
+Build packages with packetary
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-    import packetary
+Build packages::
+
+    ~/packetary$ packetary build --type rpm \
+                 --input-data packages.yaml \
+                 --output-dir /tmp/rpm/packages
+
+Format of repos.yaml and packages.yaml provided below.
+
+packages.yaml::
+
+    - source: /home/arno/projects/mirantis/mock-sandbox/zeromq
+      spec: /home/arno/projects/mirantis/mock-sandbox/zeromq/zeromq.spec
+      release: centos-5-x86_64
+
+    - source: /home/arno/projects/mirantis/mock-sandbox/zeromq
+      spec: /home/arno/projects/mirantis/mock-sandbox/zeromq/zeromq.spec
+      release: centos-7-x86_64
+
+
+Clone custom repositories
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Cloning rpm repos::
+
+    packetary clone -t rpm \
+                    -r centos_mirror.yaml \
+                    -R centos_packages.yaml \
+                    -d /tmp/mirror
+
+Clone deb repos::
+
+    packetary clone -t deb \
+                    -r ubuntu_mirrors.yaml \
+                    -R ubuntu_packages.yaml \
+                    -d /tmp/mirror
+
+where:
+
+-t - rpm or deb. In our case we work with rpm repos
+
+-r - mirror(s) list to work with
+
+-R - additional filter that should be applied to repo,
+     eg.: clone exact packages, exclude some packages by name
+     (for example, debuginfo)
