+[Mopidy](https://mopidy.com/) extension which lets you explore the JSON-RPC API.
+
+
+## Installation
+
+Install by running:
+
+```sh
+python3 -m pip install mopidy-api-explorer
+```
+
+
+## Usage
+
+Once the extension is installed, Mopidy must be restarted to detect the extension.
+After restarting Mopidy, visit the following URL to explore the Mopidy JSON-RPC API:
+
+  http://localhost:6680/api_explorer/
+
+
+## Project resources
+
+- [Source code](https://github.com/mopidy/mopidy-api-explorer)
+- [Issues](https://github.com/mopidy/mopidy-api-explorer/issues)
+- [Releases](https://github.com/mopidy/mopidy-api-explorer/releases)
+
+
+## Development
+
+### Set up development environment
+
+Clone the repo using, e.g. using [gh](https://cli.github.com/):
+
+```sh
+gh repo clone mopidy/mopidy-api-explorer
+```
+
+Enter the directory, and install dependencies using [uv](https://docs.astral.sh/uv/):
+
+```sh
+cd mopidy-api-explorer/
+uv sync
+```
+
+### Running tests
+
+To run all tests and linters in isolated environments, use
+[tox](https://tox.wiki/):
+
+```sh
+tox
+```
+
+To only run tests, use [pytest](https://pytest.org/):
+
+```sh
+pytest
+```
+
+To format the code, use [ruff](https://docs.astral.sh/ruff/):
+
+```sh
+ruff format .
+```
+
+To check for lints with ruff, run:
+
+```sh
+ruff check .
+```
+
+To check for type errors, use [pyright](https://microsoft.github.io/pyright/):
+
+```sh
+pyright .
+```
+
+### Making a release
+
+To make a release to PyPI, go to the project's [GitHub releases
+page](https://github.com/mopidy/mopidy-api-explorer/releases)
+and click the "Draft a new release" button.
+
+In the "choose a tag" dropdown, select the tag you want to release or create a
+new tag, e.g. `v0.1.0`. Add a title, e.g. `v0.1.0`, and a description of the changes.
+
+Decide if the release is a pre-release (alpha, beta, or release candidate) or
+should be marked as the latest release, and click "Publish release".
+
+Once the release is created, the `release.yml` GitHub Action will automatically
+build and publish the release to
+[PyPI](https://pypi.org/project/mopidy-api-explorer/).
