 This is the guide for the OpenAI Codex agent.
 
 ## General repository layout
-- Source code: trunk/src/ contains the C++ code for the SRS server.
-  - trunk/src/core and trunk/src/kernel contain the common definitions.
-  - trunk/src/protocol contains the media streaming protocol implementations.
-  - trunk/src/app contains the application-level implementations.
-  - trunk/src/main contains the main entry points for the programs.
-- Source code: proxy/ contains the proxy server in Go for RTMP/SRT/WebRTC proxying.
+- Source code: 
+  - `trunk/src/` contains the major C++ code for the SRS server.
+  - `trunk/src/core` and trunk/src/kernel contain the common definitions.
+  - `trunk/src/protocol` contains the media streaming protocol implementations.
+  - `trunk/src/app` contains the application-level implementations.
+  - `trunk/src/main` contains the main entry points for the programs.
+  - `proxy/` contains the proxy server in Go for RTMP/SRT/WebRTC proxying.
+  - `trunk/src/core/srs_core_autofree.hpp` defines the smart pointer; you should review it before fixing memory issues.
 - Configuration:
-  - trunk/conf/full.conf contains all supported configurations.
-  - trunk/src/app/srs_app_config.cpp parses and checks the configuration file.
-  - trunk/conf/*.conf contains other example configuration files.
-- UTests: trunk/src/utest contains the unit tests using gtest.
-- Third-party dependencies: trunk/3rdparty contains the dependency libraries. You may refer to these codes, but never attempt to change or update them.
-  - trunk/3rdparty/st-srs is the coroutine library (state-threads).
-  - trunk/3rdparty/srs-bench is the integration test tool for blackbox tests.
-  - trunk/3rdparty/gtest-fit is the gtest framework used for unit tests.
-  - trunk/3rdparty/ffmpeg-4-fit is the codec library for transcoding audio streams such as AAC with Opus.
-  - trunk/3rdparty/openssl-1.1-fit is used for RTMP handshake and WebRTC DTLS handshake.
-  - trunk/3rdparty/libsrtp-2-fit is used for SRTP in WebRTC.
-  - trunk/3rdparty/srt-1-fit is the SRT implementation.
+  - `trunk/conf/full.conf` contains all supported configurations.
+  - `trunk/src/app/srs_app_config.cpp` parses and checks the configuration file.
+  - `trunk/conf/*.conf` contains other example configuration files.
+- Tests:

 - Documentation:
-  - README.md is a brief introduction to this project.
-  - trunk/doc/CHANGELOG.md contains the changelog history.
+  - `README.md` is a brief introduction to this project.
+  - `trunk/doc/CHANGELOG.md` contains the changelog history.
+  - `trunk/doc/Dockers.md` is the guide for building Docker images.
+- Build:
+  - `trunk/configure` is the script used to configure the project; after running it, you can use make to build.
+  - `Dockerfile` is the main Docker file for building the image.
+  - `trunk/Dockerfile.test` is used to build the image for testing.
+  - `trunk/Dockerfile.builds` is used to verify builds on different target platforms.
 
 ## Testing Instructions
-- Run CI tests defined in .github/workflows/test.yml file.
+- Run CI tests defined in `.github/workflows/test.yml` file.
 - Add or update tests for the code you change, even if nobody asked.
