## What it is
NuGet Gallery is the open-source ASP.NET web application that powers nuget.org, the central package repository for the .NET ecosystem. It includes the gallery website, the NuGet V3 API implementation, background jobs, and shared service libraries.

## Use cases
- host a private NuGet package repository for my team
- search and browse .NET packages online
- publish and share my own NuGet packages
- implement the NuGet V3 protocol API
- report or fix issues with nuget.org
- run a local copy of the NuGet gallery for development

## When to choose
- you need to self-host or customize a NuGet-compatible package registry
- you want to contribute to nuget.org or understand how it works
- you need a reference implementation of the NuGet V3 API

## When to avoid
- you just want to install packages into your .NET projects (use the NuGet client tools instead)
- you need a lightweight private feed (a simple feed server like BaGet may suffice)
- you are not working in the .NET ecosystem
