-# 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`.
