 # Agent Instructions

-- A bug in some LLM coding environments makes Bazel difficult to use, so agents should rely on CMake.
+- Use the Bazel build system when interacting with this repository.
+- The CMake build system is available to help users who need it.
 - Keep both the CMake and Bazel builds working at all times.
 
+## Building with Bazel
+
+To build all code with bazel:
+```bash
+bazel build src:all
+```
+To build the Tesseract and Simplex main binaries:
+```bash
+bazel build src:tesseract src:simplex
+```
+
+## Running Tests with Bazel
+
+```bash
+bazel test src:all
