 If we are stuck in a situation where we need a long-running fork of a package, we should release it to CHaP instead (see the [CHaP README](https://github.com/IntersectMBO/cardano-haskell-packages) for more).
 
-### How to add a `source-repository-package`
-
-As an example, we show how [constrained-generators](https://github.com/input-output-hk/constrained-generators.git) was added (pinned at commit `45559e07fe1651ddd257f2a1215dfd65e30a963f`).
-
-1. Add the repository as an input to `flake.nix`:
-
-   ```nix
-   constrained-generators = {
-     url = "github:input-output-hk/constrained-generators";
-     flake = false;
-   };
-   ```
-
-2. Add an entry to `inputMap` in `flake.nix`:
-
-    ```nix
-    inputMap = {
-      ...
-      "https://github.com/input-output-hk/constrained-generators.git" = inputs.constrained-generators;
-      ...
-    };
-    ```
-
-3. Add an SRP entry to `cabal.project`:
-
-   ```
-   source-repository-package
-     type: git
-     location: https://github.com/input-output-hk/constrained-generators.git
-     tag: 45559e07fe1651ddd257f2a1215dfd65e30a963f
-   ```
-
-4. Update the nix flake:
-
-   ```
-   nix flake update constrained-generators --override-input constrained-generators github:input-output-hk/constrained-generators/45559e07fe1651ddd257f2a1215dfd65e30a963f
-   ```
+If you do add a `source-repository-package`, you need to provide a `--sha256` comment in `cabal.project` so that Nix knows the hash of the content.
