+### Installation
+
+To install cdist, execute the following commands:
+
+    git clone git://git.schottelius.org/cdist
+    cd cdist
+    export PATH=$PATH:$(pwd -P)/bin
+
+
+### Update
+
+As the stable branch always contains the stable code, you can upgrade
+cdist using
+
+    git pull
+
+If there are any incompatibilities, at least the minor version (1.0 -> 1.1)
+will change and thus a git pull will never break your cdist installation
+(in theory).
