+
+# ESPHome PR Workflow
+
+When creating a pull request for esphome, follow these steps:
+
+## 1. Create Branch from Upstream
+
+Always base your branch on **upstream** (not origin/fork) to ensure you have the latest code:
+
+```bash
+git fetch upstream
+git checkout -b <branch-name> upstream/dev
+```
+
+## 2. Read the PR Template
+
+Before creating a PR, read `.github/PULL_REQUEST_TEMPLATE.md` to understand required fields.
+
+## 3. Create the PR
+
+Use `gh pr create` with the **full template** filled in. Never skip or abbreviate sections.
+
+Required fields:
+- **What does this implement/fix?**: Brief description of changes
+- **Types of changes**: Check ONE appropriate box (Bugfix, New feature, Breaking change, etc.)
+- **Related issue**: Use `fixes <link>` syntax if applicable
+- **Pull request in esphome-docs**: Link if docs are needed
+- **Test Environment**: Check platforms you tested on
+- **Example config.yaml**: Include working example YAML
+- **Checklist**: Verify code is tested and tests added
+
+## 4. Example PR Body
+
+```markdown
+# What does this implement/fix?
+
+<describe your changes here>
+
+## Types of changes
+
+- [ ] Bugfix (non-breaking change which fixes an issue)
+- [x] New feature (non-breaking change which adds functionality)
+- [ ] Breaking change (fix or feature that would cause existing functionality to not work as expected)
+- [ ] Developer breaking change (an API change that could break external components)
+- [ ] Code quality improvements to existing code or addition of tests
+- [ ] Other
+
+**Related issue or feature (if applicable):**
+
+- fixes https://github.com/esphome/esphome/issues/XXX
+
+**Pull request in [esphome-docs](https://github.com/esphome/esphome-docs) with documentation (if applicable):**
+
+- esphome/esphome-docs#XXX
+
+## Test Environment
+
+- [x] ESP32
+- [x] ESP32 IDF
+- [ ] ESP8266
+- [ ] RP2040
+- [ ] BK72xx
+- [ ] RTL87xx
+- [ ] LN882x
+- [ ] nRF52840
+
+## Example entry for `config.yaml`:
+
+```yaml
+# Example config.yaml
+component_name:
+  id: my_component
+  option: value
+```
+
+## Checklist:
+  - [x] The code change is tested and works locally.
+  - [x] Tests have been added to verify that the new code works (under `tests/` folder).
+
+If user exposed functionality or configuration variables are added/changed:
+  - [ ] Documentation added/updated in [esphome-docs](https://github.com/esphome/esphome-docs).
+```
+
+## 5. Push and Create PR
+
+```bash
+git push -u origin <branch-name>
+gh pr create --repo esphome/esphome --base dev --title "[component] Brief description"
+```
+
+Title should be prefixed with the component name in brackets, e.g. `[safe_mode] Add feature`.
