+## 👷 CI/CD coverage
+Currently, this repository houses 2 workflows, which are executed when pushing to the v2 branch.
+
+#### ↪️ `Nix: check for unused code`
+This workflow can be found in `.github/workflows/deadnix.yaml`,
+and should be pretty self-explanatory.
+
+Here's what it does:
+1. Checks out current branch
+2. Finds any unused variables/imports etc...
+3. Creates a new commit, instantly removing any unused code
+
+#### ↪️ `Nix: validate flake`
+This workflow can be found in `.github/workflows/validate.yaml`.
+It simply validates a flake using `nix flake check`.
+
+To be specific, it does the following:
+1. Checks out current branch
+2. Installs nix with some experimental features (flakes, nix-command, recursive-nix, pipe-operator)
+3. Runs `nix flake check` on the codebase
