+# "Spell Check" workflow (Task)
+
+Workflow file: [spell-check-task.yml](spell-check-task.yml)
+
+Use [codespell](https://github.com/codespell-project/codespell) to check for commonly misspelled words in the repository files.
+
+This is the version of the workflow for projects using the [Task](https://taskfile.dev/#/) task runner tool.
+
+## Installation
+
+The `codespell` tool dependency is managed by [Poetry](https://python-poetry.org/).
+
+Install Poetry by following these instructions:<br />
+https://python-poetry.org/docs/#installation
+
+If your project does not already use Poetry, you can initialize the [`pyproject.toml`](https://python-poetry.org/docs/pyproject/) file using these commands:
+
+```
+poetry init --python="^3.9" --dev-dependency="codespell@^2.1.0"
+poetry install
+```
+
+If already using Poetry, add the tool using this command:
+
+```
+poetry add --dev "codespell@^2.1.0"
+```
+
+Make sure to commit the resulting `pyproject.toml` and `poetry.lock` files.
+
+## Assets
+
+- [.codespellrc](assets/spell-check/.codespellrc) - codespell configuration file.
+  - Install to: repository root
+- [`Taskfile.yml`](assets/spell-check-task/Taskfile.yml] - spell check and spelling correction tasks.
+  - Install to: repository root (or add the `general:general:check-spelling` and `general:correct-spelling` tasks into the existing `Taskfile.yml`)
+- [`Taskfile.yml`](assets/shared/Taskfile.yml] - Installation task.
+  - Add the `poetry:install-deps` task into the existing `Taskfile.yml`
+
+## Readme badge
+
+Markdown badge:
+
+```markdown
+[![Spell Check status](https://github.com/REPO_OWNER/REPO_NAME/actions/workflows/spell-check-task.yml/badge.svg)](https://github.com/REPO_OWNER/REPO_NAME/actions/workflows/spell-check-task.yml)
+```
+
+Replace the `REPO_OWNER` and `REPO_NAME` placeholders in the URLs with the final repository owner and name ([example](https://raw.githubusercontent.com/arduino-libraries/ArduinoIoTCloud/master/README.md)).
+

+
+Asciidoc badge:

+```
+
+Define the `{repository-owner}` and `{repository-name}` attributes and use them throughout the readme ([example](https://raw.githubusercontent.com/arduino-libraries/WiFiNINA/master/README.adoc)).
+
+## Commit message
+
+```
+Add CI workflow to check for commonly misspelled words
+
+On every push, pull request, and periodically, use the codespell to check for commonly
+misspelled words.
+
+In the event of a false positive, the problematic word should be added, in all lowercase, to the ignore-words-list field
+of ./.codespellrc. Regardless of the case of the word in the false positive, it must be in all lowercase in the ignore
+list. The ignore list is comma-separated with no spaces.
