# Installation Phases

This directory is reserved for future ordered Atlas installation phases.

Phase 2A intentionally did not create speculative .NET, SQL Server, nginx, or Docker installer scripts. Phase 2 adds the .NET installer only.

## Naming Convention

Use a two-digit phase number and lower-case hyphenated component name:

```text
10-dotnet.sh
20-sql-server.sh
30-nginx.sh
40-docker.sh
90-validate-platform.sh
```

Each phase must source the shared framework under `install/lib/`, support dry-run behaviour where practical, and follow [../../SERVER-STANDARDS.md](../../SERVER-STANDARDS.md).

## Current Phases

- `10-dotnet.sh`: installs the required .NET 8 and .NET 10 SDKs from official Ubuntu package sources.

Installed SDKs after the current Phase 2 run:

- .NET 8 SDK `8.0.128`
- .NET 10 SDK `10.0.109`
