## What it is
A JetBrains IDE plugin that adds support for .gitignore and many other ignore file formats (.dockerignore, .npmignore, .eslintignore, etc.). It provides syntax highlighting, inspections with quick-fixes, and rule generation from GitHub's template collection.

## Use cases
- syntax highlighting for .gitignore files in IntelliJ IDEA
- generate gitignore rules from GitHub templates
- find duplicated or unused entries in .gitignore
- add files to gitignore from a popup menu
- show which files are ignored by a gitignore file
- create .dockerignore or .npmignore with editor support

## When to choose
- you use IntelliJ-based IDEs (IDEA, PyCharm, WebStorm, GoLand, etc.) and work with gitignore or other ignore files
- you want inspections and quick-fixes for ignore file syntax errors
- you want to generate ignore rules from templates

## When to avoid
- you use VS Code or another non-JetBrains editor
- you need ignore file handling outside an IDE
- you are on an old IDE version no longer receiving 4.x updates
