+# NAME
+
+labwc - environment
+
+# DESCRIPTION
+
+The environment file is parsed as <variable>=<value> and sets environment
+variables accordingly.
+
+Note that the environment file is treated differently by openbox where
+it is simply sourced prior to running openbox.
+
+# CONFIGURATION
+
+It is recommended to specify keyboard settings here. See
+xkeyboard-config(7) for details.
+
+For example, this sets keyboard layout to Swedish:
+
+```
+XKB_DEFAULT_LAYOUT=se
+```
+
+The following environment variables are supported by labwc:
+
+*LABWC_ADAPTIVE_SYNC*
+	Set to 1 enable adaptive sync
+
