-# Go analysis support for CodeQL
+# Relocation notice: `github/codeql-go` moved into `github/codeql`
 
-This open-source repository contains the extractor, CodeQL libraries, and queries that power Go
-support in [LGTM](https://lgtm.com) and the other CodeQL products that [GitHub](https://github.com)
-makes available to its customers worldwide.
+- Old location: The `github/codeql-go` repository
+- New location: The `github/codeql` repository, specifically https://github.com/github/codeql/tree/main/go.
+- Detailed announcement: https://github.com/github/codeql-go/issues/741
 
-It contains two major components:
-  - an extractor, itself written in Go, that parses Go source code and converts it into a database
-    that can be queried using CodeQL.
-  - static analysis libraries and queries written in [CodeQL](https://codeql.github.com/docs/) that can be
-    used to analyze such a database to find coding mistakes or security vulnerabilities.
+This repository previously contained the open-source CodeQL queries, libraries, and extractor for analyzing codebases written in the Go programming language with GitHub's CodeQL code analysis tools. These contents have been moved to the `github/codeql` repository, to live alongside similar libraries for all other programming languages supported by CodeQL.
 
-The goal of this project is to provide comprehensive static analysis support for Go in CodeQL.
+CodeQL support of the Go programming language remains the same, except that the code and the development will continue in `github/codeql`.
 
-For the queries and libraries that power CodeQL support for other languages, visit [the CodeQL
-repository](https://github.com/github/codeql).
-
-## Installation
-
-Clone this repository.
-
-Run `scripts/install-deps.sh`. This will ensure that the necessary external CodeQL packs are
-downloaded to your machine. You will need to re-run this script whenever you pull new commits from
-the repo.
-
-If you want to use the CodeQL extension for Visual Studio Code, import this repository into your VS
-Code workspace.
-
-## Usage
-
-To analyze a Go codebase, either use the [CodeQL command-line
-interface](https://codeql.github.com/docs/codeql-cli/) to create a database yourself, or
-download a pre-built database from [LGTM.com](https://lgtm.com/). You can then run any of the
-queries contained in this repository either on the command line or using the VS Code extension.
-
-Note that the [lgtm.com](https://github.com/github/codeql-go/tree/lgtm.com) branch of this
-repository corresponds to the version of the queries that is currently deployed on LGTM.com.
-The [main](https://github.com/github/codeql-go/tree/main) branch may contain changes that
-have not been deployed yet, so you may need to upgrade databases downloaded from LGTM.com before
-running queries on them.
