+# Simdock Screenshots
+
+Put release-ready screenshots in this directory.
+
+Recommended files:
+
+- `simdock-dark-ios.png`
+- `simdock-dark-android-installing.png`
+- `simdock-light-ready.png`
+
+Guidelines:
+
+- Use PNG for README screenshots.
+- Prefer `1600px` or `1920px` width so GitHub can scale down cleanly.
+- Avoid personal paths, usernames, tokens, device UDIDs, or private project names.
+- Capture both dark and light themes only when they communicate different UI states.
+- Keep source screenshots uncompressed; optimize copies for release notes if needed.
