+## How to build ##
+There are two way to build telemetry service:
+- using bitbake in yocto environment
+- using meson as native build
+
+To build it using bitbake follow the guide from OpenBMC docs`[5]`.
+To build it using meson follow the quick guide to install meson`[6]` and then
+run below commands
+```
+meson build
+cd build
+ninja
+```
+After successful build you should be able to run telemetry binary or start unit
+tests
+```
+./tests/telemetry-ut
+./telemetry
+```
+In case if system is missing boost dependency, it is possible to build it
+locally and set BOOST_ROOT environment variable to location of built files for
+meson. After this change meson should be able to detect boost dependency. See
+`[7]` for more details.
+
+## Notes ##
+More information can be found in OpenBMC docs repository `[8]`.
