+
+## Problem Statement
+
+Previously, the RepoContext component in Copilot Chat only worked with GitHub repositories. 
+When users had repositories hosted on other platforms (Azure DevOps, GitLab, Bitbucket, etc.) 
+or local repositories, the RepoContext would return empty and provide no useful repository 
+information to the AI assistant.
+
+This limited the usefulness of Copilot Chat for:
+- CI/CD tools working with non-GitHub repositories
+- Enterprise users with Azure DevOps repositories
+- Open source projects hosted on GitLab
+- Local development workflows
+
+## Solution Overview
+
+The RepoContext class has been enhanced to work with any Git repository by:
+
+1. **Maintaining backward compatibility** - GitHub repositories continue to work exactly as before
+2. **Adding Azure DevOps support** - Full integration with Azure DevOps repositories
+3. **Adding generic Git support** - Basic information extraction from any Git repository
+4. **Graceful fallback** - Provides basic Git context even when remote information is unavailable
+
+## Implementation Details
+
+### Before (GitHub only)
+```typescript
+const repoContext = activeRepository && getGitHubRepoInfoFromContext(activeRepository);
+if (!repoContext || !activeRepository) {
+    return; // No context provided for non-GitHub repos
+}
+```
+
+### After (All repository types)
+```typescript
+const githubRepoContext = getGitHubRepoInfoFromContext(activeRepository);
+let repoInfo;
+let remoteUrl;
+
+if (githubRepoContext) {
+    // GitHub repository - use existing logic
+    repoInfo = { org: githubRepoContext.id.org, repo: githubRepoContext.id.repo, type: 'github' };
+    remoteUrl = githubRepoContext.remoteUrl;
+} else {
+    // Try Azure DevOps and other supported providers
+    const repoInfos = Array.from(getOrderedRepoInfosFromContext(activeRepository));
+    if (repoInfos.length > 0) {
+        const firstRepoInfo = repoInfos[0];
+        if (firstRepoInfo.repoId.type === 'ado') {
+            repoInfo = { org: firstRepoInfo.repoId.org, repo: firstRepoInfo.repoId.repo, type: 'azure-devops' };
+        }
+    } else {
+        // Fallback: extract basic info from any Git repository
+        const fetchUrl = activeRepository.remoteFetchUrls?.[0];
+        if (fetchUrl) {
+            const parsed = parseRemoteUrl(fetchUrl);
+            const pathMatch = parsed?.path.match(/^\/?([^/]+)\/([^/]+?)(\/|\.git\/?)?$/i);
+            if (pathMatch) {
+                repoInfo = { org: pathMatch[1], repo: pathMatch[2], type: 'generic' };
+            }
+        }
+    }
+}
+
+// Always provide some context, even if just basic Git info
+if (!repoInfo) {
+    return <Tag name='repoContext'>
+        Current branch: {activeRepository.headBranchName}<br />
+        {activeRepository.upstreamBranchName ? <>Upstream branch: {activeRepository.upstreamBranchName}<br /></> : ''}
+    </Tag>;
+}
+```
+
+## Enhanced Output
+
+The RepoContext now provides richer information including:
+
+### GitHub Repositories
+```
+Repository name: vscode-copilot-chat
+Owner: microsoft
+Repository type: github
+Current branch: main
+Default branch: main
+Remote URL: https://github.com/microsoft/vscode-copilot-chat.git
+```
+
+### Azure DevOps Repositories
+```
+Repository name: myrepo
+Owner: myorg
+Repository type: azure-devops
+Current branch: main
+Upstream branch: origin/main
+Remote URL: https://dev.azure.com/myorg/myproject/_git/myrepo
+```
+
+### Generic Git Repositories (GitLab, Bitbucket, etc.)
+```
+Repository name: myrepo
+Owner: myorg
+Repository type: generic
+Current branch: main
+Upstream branch: origin/main
+Remote URL: https://gitlab.com/myorg/myrepo.git
+```
+
+### Local Repositories (no remote)
+```
+Current branch: main
+Upstream branch: origin/main
+Upstream remote: origin
+```
+
+## Benefits
+
+1. **CI/CD Integration**: CI/CD tools can now get repository context regardless of hosting provider
+2. **Enterprise Support**: Full support for Azure DevOps repositories commonly used in enterprises
+3. **Open Source Flexibility**: Works with GitLab, Bitbucket, and other Git hosting platforms
+4. **Local Development**: Provides useful context even for local repositories
+5. **Backward Compatibility**: No breaking changes for existing GitHub users
+
+## Testing
+
+The implementation includes comprehensive tests:
+
+- Unit tests for core functionality
+- Integration tests for different repository types
+- Manual verification scripts
+- Real-world scenario testing
+
+## Usage Examples
+
+### For CI/CD Tools
+```typescript
+// The RepoContext now provides repository information for any Git repository
+// This enables CI/CD tools to get context about the current repository
+// regardless of whether it's hosted on GitHub, Azure DevOps, GitLab, etc.
+```
+
+### For Enterprise Users
+```typescript
+// Azure DevOps users now get full repository context
+// including organization, project, and repository information
+```
+
+### For Open Source Projects
+```typescript
+// GitLab, Bitbucket, and other Git hosting platforms
+// now provide basic repository context to improve AI responses
+```
+
+This enhancement makes Copilot Chat more useful and accessible to users working with diverse 
+repository hosting solutions, addressing the core issue raised in VSCode #256753.
