docs: clarify GitHub first screen for Cap self-hosting - #2
Conversation
Lead with self-hosted Cap-compatible recording server in Rust, why it exists, a one-line local run, and that Cap Desktop talks to this service. Co-authored-by: Lawrence <lawrence-millard@users.noreply.github.com>
📝 WalkthroughWalkthroughThe README now presents the project as a self-hosted Cap-compatible recording server. It adds Docker Compose, ChangesDocumentation update
Estimated code review effort: 1 (Trivial) | ~2 minutes Merge Risk: 🟡 Moderate · up to The README currently implies a one-command local setup and does not clearly provide the required configuration or Desktop URL, which may prevent users from starting or connecting to the service. Correct the setup instructions before merging. Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)
✨ Finishing Touches🧪 Generate unit tests (beta)

- Around line 11-14: Update the README’s local Docker workflow documentation
before the docker compose up -d command to list required DATABASE_URL, WEB_URL,
and SIGN_SECRET values and state that Postgres must be provided externally
because no Postgres service is defined. In the Desktop configuration
instruction, use the concrete URL http://localhost:8080 rather than the WEB_URL
environment-variable name.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Document the required Compose configuration before the startup command.
docker-compose.yml declares DATABASE_URL, WEB_URL, and SIGN_SECRET without defaults. It also does not define a Postgres service. A user who runs only docker compose up -d does not receive a complete local setup and may start the server with empty configuration or without a reachable database.
Document the required environment values and external Postgres prerequisite. Also set Desktop's URL to the concrete value http://localhost:8080; WEB_URL is the environment variable name, not the URL value.
Suggested wording
-Local: `docker compose up -d`,
-then set Desktop's Cap Server URL to `WEB_URL` (`http://localhost:8080` by
-default).
+Set the required environment values, including `DATABASE_URL`,
+`SIGN_SECRET`, and `WEB_URL=http://localhost:8080`. Ensure Postgres is
+reachable, then run `docker compose up -d`. Set Desktop's Cap Server URL to
+`http://localhost:8080`.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

The GitHub landing page should tell a stranger in about ten seconds that this is a self-hosted Cap-compatible recording server in Rust that Cap Desktop talks to.
