+The `aspire deploy` command manages deployment state through cached configuration files stored locally on your machine. This caching mechanism streamlines repeated deployments by preserving provisioning settings and parameters, making subsequent deployments faster and more efficient.
+
+## Default behavior
+


Please add an introductory sentence, or short paragraph to describe this section.

Added introductory paragraph to the "Default behavior" section in commit 4ed162e.

+### First deployment
+
+When you run `aspire deploy` for the first time, the command:


For the first time, or for the first time in a target --environment.

Updated to clarify "for the first time, or for the first time in a target --environment" in commit 4ed162e.

References to files should be italicized, not code blocks.

Changed file references to italics throughout the document in commit 4ed162e.

Again, please add an intro paragraph here. Perhaps use this opportunity to explain why environment-specific deploys are important.

Added introductory paragraph explaining the importance of environment-specific deployments in commit 4ed162e.

It might be really nice to include a simple GitHub example, that conceptually describes and shows how to persist the local state using @actions/cache or something like that.

Added a complete "Use deployment state in CI/CD pipelines" section with a GitHub Actions example showing how to cache deployment state using actions/cache in commit 4ed162e. The example includes cache key strategies and a security caution about managing sensitive values.

Hey @copilot please move this out of the Azure TOC section, as it's not specific to Azure. Also, please rename the doc, the H1 and the TOC entry to Deployment state caching.

Hey @copilot please move this out of the Azure TOC section, as it's not specific to Azure. Also, please rename the doc, the H1 and the TOC entry to Deployment state caching.

Moved the documentation out of the Azure TOC section to sit directly under "Publish and Deploy" in commit 5ab8d29. Also renamed:

File: local-deployment-state.md → deployment-state-caching.md
Location: deployment/aspire-deploy/ → deployment/
Title/H1: "Local deployment state" → "Deployment state caching"
TOC entry: "Local deployment state" → "Deployment state caching"

Updated all references and added a redirect for the old URL.

Hey @copilot do we need to also cache the deployment state after the deploy here too?

The actions/cache@v4 action automatically saves the cache after the job completes successfully - no additional step needed. Updated the explanation in commit 2d0bdce to explicitly mention that the cache is automatically saved after the deployment step runs.
