+When you cannot decide how many data sources to load at the beginning, you will still be able to **Append()** them later.
 
 ```go
 err := cfg.Append("other file", []byte("other raw data"))
 ```
 
+If you have a list of files with possibilities that some of them may not available at the time, and you don't know exactly which ones, you can use `LooseLoad` to ignore nonexistent files without returning error.
+
+```go
+cfg, err := ini.LooseLoad("filename", "filename_404")
+```
+
+The cool thing is, whenever the file is available to load while you're calling `Reload` method, it will be counted as usual.
+
+#### Ignore cases of key name
+
+When you do not care about cases of section and key names, you can use `InsensitiveLoad` to force all names to be lowercased while parsing.
+
+```go
+cfg, err := ini.InsensitiveLoad("filename")
+//...
+
+// sec1 and sec2 are the exactly same section object
+sec1, err := cfg.GetSection("Section")
+sec2, err := cfg.GetSection("SecTIOn")
+
+// key1 and key2 are the exactly same key object
+key1, err := sec1.GetKey("Key")
+key2, err := sec2.GetKey("KeY")
+```
+
+#### MySQL-like boolean key 
+
+MySQL's configuration allows a key without value as follows:
+
+```ini
+[mysqld]
+...
+skip-host-cache
+skip-name-resolve
+```
+
+By default, this is considered as missing value. But if you know you're going to deal with those cases, you can assign advanced load options:
+
+```go
+cfg, err := ini.LoadSources(ini.LoadOptions{AllowBooleanKeys: true}, "my.cnf"))
+```
+
+The value of those keys are always `true`, and when you save to a file, it will keep in the same foramt as you read.
+
+To generate such keys in your program, you could use `NewBooleanKey`:
+
+```go
+key, err := sec.NewBooleanKey("skip-host-cache")
+```
+
+#### Comment
+
+Take care that following format will be treated as comment:
+
+1. Line begins with `#` or `;`
+2. Words after `#` or `;`
+3. Words after section name (i.e words after `[some section name]`)
+
+If you want to save a value with `#` or `;`, please quote them with ``` ` ``` or ``` """ ```.
+
+Alternatively, you can use following `LoadOptions` to completely ignore inline comments:
+
+```go
+cfg, err := ini.LoadSources(ini.LoadOptions{IgnoreInlineComment: true}, "app.ini"))
+```

 在获取所有键值的过程中，特殊语法 `%(<name>)s` 会被应用，其中 `<name>` 可以是相同分区或者默认分区下的键名。字符串 `%(<name>)s` 会被相应的键值所替代，如果指定的键不存在，则会用空字符串替代。您可以最多使用 99 层的递归嵌套。

+### Combining short Bool options
+
+Traditional use of boolean options using their shortnames look like this:
+```
+# cmd foobar -s -o
+```
+
+Suppose you want users to be able to combine your bool options with their shortname.  This
+can be done using the **UseShortOptionHandling** bool in your commands.  Suppose your program
+has a two bool flags such as *serve* and *option* with the short options of *-o* and
+*-s* respectively. With **UseShortOptionHandling** set to *true*, a user can use a syntax
+like:
+```
+# cmd foobar -so
+```
+
+If you enable the **UseShortOptionHandling*, then you must not use any flags that have a single
+leading *-* or this will result in failures.  For example, **-option** can no longer be used.  Flags
+with two leading dashes (such as **--options**) are still valid.
