+# Microbenchmarks
+
+A collection of microbenchmarks for C++ code. 
+
+
+## Building
+The project relies on CMake to build the code.
+```
+# clone the current project then create a build configuration by running
+cmake -B build [path_to_repository]
+make -C build
+```
+you can specify another build program by providing the option `-G`,
+ for example to use Ninja `-G Ninja`.
+ The commands executes will then be
+ ```
+cmake -B build [path_to_repository]
+ninja -C build
+ ```
+To execute the code you can just run
+```
+build/microbenchmarks
+```
+
+## Add another benchmark
+If you want to add another benchmark you can
+add a c++ into benchmarks and then add it to the `CMakeLists.txt` file in the target sections.
