-## Installation
 
-Cdist stable always in master
+## Getting cdist
 
- * Create a new unpriviliged user (probably "cdist")
- * Become that user, execute the following code:
+You can clone cdist from git, which gives you the advantage of having
+a version control in place for development of your own stuff as well.
 
-git clone git://git.schottelius.org/cdist
-cd cdist
-export PATH=$PATH:$(pwd -P)/bin
+There are at least two branches available:
 
-That's it.
+ * 1.0: stable branch of version 1.0
+ * next: preparing next cdist version
 
-Operation on the server is run as "cdist" user.
-Operation on the client is run as "root" user.
+Other branches may be available as well for features or bugfixes, but they
+may vanish at any point.
 
-## Update
 
-git pull && make install
+### 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).
