+# v2.5.2
+## Fixes
+- Fixes an issue where a namespace may not be properly applied if applying the Helm template without a namespace specified / using `kubectl apply -f` directly with the rendered template.
+- Fixes an issue where the error message from a failed Enrollment API call is not logged.
+## Chores
+- Update GitHub Actions workflow to check for policy enforcement on Helm chart rendered manifests in addition to checking for drift in generated CRDs.
+- Fixes various linting issues in the codebase.
+
 # v2.5.1
 ## Fixes
 - Fixes an issue where OAuth 2.0 client credentials were being regenerated on every API call.

+# Command Cert Manager Issuer Contribution Guide
+
+## Requirements
+- Go (>= 1.24)
+- golangci-lint (>= 2.4.0) ([installation notes](https://github.com/golangci/golangci-lint?tab=readme-ov-file#install-golangci-lint))
+- helm (>= 3.x) — required to render chart templates for manifest linting ([installation notes](https://helm.sh/docs/intro/install/))
+- conftest — policy testing tool powered by Open Policy Agent; installed automatically by `make lint-manifests`
+
+## Installing dependencies
+Project dependencies can be installed by running the following:
+
+```bash
+go mod download
+```
+
+The following command can be used to add missing requirements or remove unused modules:
+
+```bash
+go mod tidy
+```
+
+## Running unit tests
+The following command can be run to run the project unit tests:
+
+```bash
+go test -v ./...
+```
+
+## Running linters
+The project uses golangci-lint to lint the codebase. The following command can be run to run the linters:
+
+```bash
+golangci-lint run
+```
+
+or, alternatively:
+
+```bash
+make lint
+```
+
+## Updating generated manifests
+
+This command will update the generated custom resource definitions under `config/crd/bases`:
+
+```bash
+make generate manifests
+```
+
+> [!IMPORTANT]
+> There is no automated process to automatically update the CRDs under `deploy/charts/command-cert-manager-issuer`. If any changes are made to the CRDs, the generated CRDs under `config/crd/bases` must be copied to `deploy/charts/command-cert-manager-issuer/crds` to ensure the Helm chart is up to date.
+
+## Linting Helm manifests
+
+The Helm chart under `deploy/charts/command-cert-manager-issuer` is linted with two tools on every PR:
+- **conftest** — runs custom Rego policies located in the [`policy/`](policy/) directory against the rendered manifests
+
+To run both checks locally:
+
+```bash
+make lint-manifests
+```
+
+`conftest` is downloaded automatically into `bin/` on first use; no manual installation is required.
+
+To inspect the rendered templates without linting:
+
+```bash
+make helm-template
+```
+
+### Adding or modifying policies
+
+Rego policies live in [`policy/`](policy/). Each `.rego` file in that directory is evaluated by conftest against every resource in the rendered chart. Add a new `.rego` file to enforce additional rules. For example, `policy/roles.rego` enforces that all `Role` resources declare an explicit namespace.
+
+kube-linter checks can be tuned in [.kube-linter.yaml](.kube-linter.yaml). To exclude a check, add its name under the `exclude` key.
+
+## Running end-to-end tests
+A comprehensive end-to-end test suite is available to verify the issuer code works against cert-manager and a Keyfactor Command instance.
+
+Instructions on how to run the end-to-end test suite can be found [here](./e2e/README.md).
