-you will find a list of `wget` commands that can be executed to get the dependencies.
-
-I needed to add `--no-check-certificate` to the OpenSSL wget line to make it work.
-Likely this is because the ca-certificates in Debian 7.4 is fairly old. This does not create a 
-security issue as the gitian descriptors check the integrity of the input archives and refuse to work
-if any one is corrupted.
-
-After downloading the archives, execute the `gbuild` commands to build the dependencies.
-This can take a long time, but only has to be done when the dependencies change, for example
-to upgrade the used version.
-
-**Note**: Do not forget to copy the result from `build/out` to `inputs` after every gbuild command! This will save
-you a lot of time.

-At any time you can check the package installation and build progress with
