-# Haskell Horizon Platform
+# Horizon Haskell Platform
 
 [horizon-haskell.net](https://horizon-haskell.net).
 
-Horizon is a haskell package set targetting new builds of GHC.
+horizon-platform is a haskell package set targetting new builds of GHC. This package set extends [horizon-platform](https://gitlab.horizon-haskell.net/package-sets/horizon-platform).
 
-## Updating the package set
 
-The package set is generated from the `manifest.dhall` using the following command:
+The following things are expected to be here:
+* aeson
+* beam-postgres
+* composite-base
+* dhall
+* hedgehog
+* hoauth2-providers
+* log-effectful
+* persistent-postgresql
+* polysemy
+* servant
+* souffle-haskell
+* streamly
+* sydtest
+* tasty
+* wai-app-static
+* warp
+
+## Updating the Package Set
+
+Generating the nix expressions for the package set is a two step process.
+
+1. Edit the `horizon.dhall` file.
+2. Generate the nix expressions with
+
+```
+nix run develop/#horizon-gen-nix -- -jN
+```
+
+You can edit the `horizon.dhall` file in one of two ways: manually using a text
+editor, or programatically using `horizon-shell`.
+
+If you want to bumping everything listed in the `horizon.dhall` file to the latest
+bounds, run
+
+```
+nix run develop/#try-to-upgrade-everything
+```
+
+### Using horizon-shell.
+
+To use `horizon-shell`.
 
 ```
-nix run .#horizon-gen-nix
+nix run develop/#horizon-shell
 ```
 
-This will generate both the `pkgs` folder and the `overlay.nix`. If you want to
-regenerate a particular package in `pkgs`, delete that file from `pkgs`. To
-regenerate the entire package set from scratch, delete the `pkgs` folder.
+This is a haskell interpreter with a few shortcut functions available. Running
+`tryToUpgradeEverything` will poll hackage for any potential updates and add
+them to the dhall file. This will only modify the dhall, not the nix
+expressions. You must remember to run `nix run develop/#horizon-gen-nix`
+afterwards.
+
+To quickly add a new package to the dhall, use the `addHackage` function. For example
+`addHackage "optics"`.
+
+## Tweaking & Hacking
 
 If you need to do additional manual overrides to the nix code, such as
-`addPkgconfigDepends`, edit the `configuration.nix` overlay, which is applied
-after `overlay.nix`.
+`addPkgconfigDepends`, edit the `configuration/common.nix` overlay, which is
+applied over the generated derivations.
+
+## Feedback
+
+To build all packages, run
+
+```
+nix run develop/#feedback -- build
+```
+
+## Hoogle
+
+To get a hoogle instance for the entire package set, you can run:
+
+```
+nix run .#apps.x86_64-linux.run-hoogle
+```
