+* *git*: Needed to download bleeding edge/experimental source code (Optional)
+
+SvxLink depend on some third party libraries. Since packages are named
+differently in different distributions you need to do some research to find out
+exactly what the packages are called in your distribution. Packages usually are
+devided in two parts, a runtime part and a development part. Both are needed to
+compile SvxLink. The development packages usually have a name ending in "-dev"
+or "-devel".

+== Required system user ==
+Before trying to build and install using the commands below you also need to

+How to create users and groups vary between different Linux distributions.
+A common command that exist on many distributions is 'useradd'. The 'daemon'
+group usually exist but if not, look for the 'groupadd' command.
