+### How to compile the guardrail script from source
+
+To compile the current version of the guardrail script yourself, you first have to clone the plutus repository
+```bash
+git clone https://github.com/IntersectMBO/plutus.git
+cd plutus
+```
+Next we check out the version 1.31.0.0 of plutus and enter a nix development shell via
+```bash
+git checkout 1.31.0.0
+nix develop
+```
+We then create a file `cabal.project.local` to override some dependencies as a hotfix (there is a circular dependency otherwise).
+```cabal
+cat <<EOF > cabal.project.local
+allow-newer: *:plutus-ledger-api
+allow-newer: *:prettyprinter-configurable
+EOF
+```
+Next, we open in a text editor the file `cardano-constitution/cardano-constitution.cabal` and delete line 134 that reads `buildable:      False` via
+```bash
+sed -i '134d' cardano-constitution/cardano-constitution.cabal
+```
+Next, we can build the script via
+```bash
+cabal update
+cabal run cardano-constitution:create-json-envelope -- guardrail.plutus
+```
+You can get the hash of this just compiled script via, for example
+```bash
+cardano-cli transaction policyid --script-file guardrail.plutus
+```
+And compare it to the one currently defined [here](https://book.world.dev.cardano.org/environments/mainnet/conway-genesis.json).
