-To build this package, do the following steps:
+### Compile ipmid with default options:
+```ascii
+meson builddir
+ninja -C builddir
+```
+### Compile ipmid with yocto defaults:
+```ascii
+meson builddir -Dbuildtype=minsize -Db_lto=true -Dtests=disabled
+ninja -C builddir
+```
+If any of the dependencies are not found on the host system during
+configuration, meson automatically gets them via its wrap dependencies
+mentioned in `ipmid/subprojects`.
- 1. ./bootstrap.sh
- 2. ./configure ${CONFIGURE_FLAGS}
- 3. make
-
-To clean the repository run `./bootstrap.sh clean`.
+### Enable/Disable meson wrap feature
+```ascii
+meson builddir -Dwrap_mode=nofallback
+ninja -C builddir
+```
+### Enable debug traces
+```ascii
+meson builddir -Dbuildtype=debug
+ninja -C builddir
+```
+### Generate test coverage report:
+```ascii
+meson builddir -Db_coverage=true -Dtests=enabled
+ninja -C builddir test
+ninja -C builddir coverage
+```
