+=== OpenEmbedded and Yocto
+
+LTTng{nbsp}{revision} recipes are available in the

+layer for Yocto Project{nbsp}2.3 _Pyro_ under the following names:
+
+* `lttng-tools`
+* `lttng-modules`
+* `lttng-ust`
+
+With BitBake, the simplest way to include LTTng recipes in your target
+image is to add them to `IMAGE_INSTALL_append` in path:{conf/local.conf}:
+
+----
+IMAGE_INSTALL_append = " lttng-tools lttng-modules lttng-ust"
+----
+
+If you use Hob:
+
+. Select a machine and an image recipe.
+. Click **Edit image recipe**.
+. Under the **All recipes** tab, search for **lttng**.
+. Check the desired LTTng recipes.
