 SpaceVim loads custom global configuration from `~/.SpaceVim.d/init.toml`. It also supports project specific configuration.

+### Why the option in toml file does not applied?
+
+Many people have encountered the same problem. the option has been added in init.toml. but SpaceVim do not use it.
+One possibility is that there is a syntax error in tomL. For example:
+
+```
+[options]
+    enable_statusline_mode = true
+    enable_tabline_filetype_icon = true
+    enable_os_fileformat_icon = true
+    statusline_unicode_symbols = true
+    line_on_the_fly = false
+[[layers]]
+    name = 'core'
+    enable_filetree_gitstatus = true
+    enable_filetree_filetypeicon = true
+
+[options]
+    bootstrap_before = 'myspacevim#before'
+```
+
+In this example, only `bootstrap_before` option will be used. So there should only one `[options]` section in toml file.
