+# Examples
+This folder contains code examples for the C and C++ APIs.
+
+## Build with cmake
+To build the examples with cmake, run the following commands from the root of the repository:
+
+```
+cd examples/c
+mkdir cmake_build
+cd cmake_build
+cmake ..
+cmake --build .
+```
+
+To build the C++ examples, run the same commands from examples/cpp:
+
+```
+cd examples/cpp
+mkdir cmake_build
+cd cmake_build
+cmake ..
+cmake --build .
+```
+
+This will produce two binaries for each example: one that links with a shared Flecs library, and one that is linked with static Flecs library. The binaries linked with the static library have the postfix _static.
+
+To run a single example, execute it from the `cmake_build` directory:
+
+```
+./entities_basics_static
+```
+
+## Build with bake
+To build the examples with bake, run bake once in the root of the repository, so it knows where to find Flecs:
+
+```
+bake
+```
+
+To run a single example, use the following command:
+
+```
+bake run examples/c/entities/basics
+```
+
+To run a single example with optimizations enabled, use the following command:
+
+```
+bake run examples/c/entities/basics --cfg release
+```
+
+To build all examples, run the following command:
+
+```
+bake examples
+```
+
+See the [bake repository](https://github.com/SanderMertens/bake) for instructions on how to install bake.
