-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).
+
+
+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
 
-## Package Set Policy
-
-This package set has the following policy.
-
-* GHC will advance as often as possible
-* Nonversioned locations (git, unversioned tarballs) are permitted to allow
-  GHC to advance.
-* The following packages must always build:
-  * aeson
-  * beam-postgres
-  * composite-base
-  * dhall
-  * haskell-language-server
-  * hedgehog
-  * pandoc
-  * persistent-postgresql
-  * polysemy
-  * servant
-  * sydtest
-  * tasty
-  * wai-app-static
-  * warp
-
-## Updating the package set
-
-The package set is generated from the `horizon.dhall`. You can edit this in one
-of two ways: manually using a text edit, or programatically using
-`horizon-shell`.
-
-### Manual
+```
+nix run develop/#horizon-gen-nix -- -jN
+```
 
-Edit the `horizon.dhall` file and add or change some package data.
+You can edit the `horizon.dhall` file in one of two ways: manually using a text
+editor, or programatically using `horizon-shell`.
 
-Run `horizon-gen-nix` from the remote repository.
+If you want to bumping everything listed in the `horizon.dhall` file to the latest
+bounds, run
 
 ```
-nix run 'git+https://gitlab.horizon-haskell.net/haskell/horizon-gen-nix?ref=refs/tags/0.10.0'
+nix run develop/#try-to-upgrade-everything
 ```
 
-### Programatic
+### Using horizon-shell.
 
 To use `horizon-shell`.
 
 ```
-nix develop
+nix run develop/#horizon-shell
 ```
 
-See the in-shell help for usage.
+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.
 
-### Tweaking
+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/common.nix` overlay, which is
-applied last.
+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
+```
