-## Generation of runtime configuration files
-
-The run-time configuration files of the Daedalus wallet are generated during the
-installer build, and are governed by configuration files written in the Dhall
-configuration language, which are factored per OS and target cluster:
-
-  - https://github.com/input-output-hk/daedalus/tree/develop/installers/dhall
-
-The Dhall expressions that comprise the runtime configuration are thus composed from:
-  - `launcher.dhall` -- top level expression defining the launcher configuration YAML file
-  - `topology.dhall` -- top level expression defining the wallet topology YAML file
-  - `{linux64,macos64,win64}.dhall`
-  - `{mainnet,staging,testnet}.dhall`
-
-The set of clusters (currently `mainnet` and `staging`) that the build scripts
-(`scripts/build-installer-*`) will build installers for is enumerated in
-https://github.com/input-output-hk/daedalus/blob/develop/installer-clusters.cfg
-
-### Validating the Dhall configuration files
-
-The entire set of configuration files can be validated by typechecking all
-possible combinations:
-
-    $ cd installers
-    $ ghci Config.hs
-    GHCi, version 8.0.2: http://www.haskell.org/ghc/  :? for help
-    Loaded GHCi configuration from /home/deepfire/.ghci
-    [1 of 2] Compiling Types            ( Types.hs, interpreted )
-    [2 of 2] Compiling Config           ( Config.hs, interpreted )
-    Ok, modules loaded: Config, Types.
-    *Config> generateAllConfigs "./dhall"
-
-..which will be silent if everything is well, and will otherwise provide
-a detailed explanation of what is wrong, and where.

 Before signing the Mac installer, the keychain needs to be set up. Do this by running:
