+
+## Install
+
+```shell
+    go get github.com/gobwas/glob
+```
+
+## Example
+
+```go
+
+package main
+
+import "github.com/gobwas/glob"
+
+func main() {
+    var g glob.Glob
+    
+    // create simple glob
+    g = glob.MustCompile("*.github.com")
+    g.Match("api.github.com") // true
+    
+    // quote meta characters and then create simple glob 
+    g = glob.MustCompile(glob.QuoteMeta("*.github.com"))
+    g.Match("*.github.com") // true
+    
+    // create new glob with set of delimiters as ["."]
+    g = glob.MustCompile("api.*.com", '.')
+    g.Match("api.github.com") // true
+    g.Match("api.gi.hub.com") // false
+

+    // create glob with single symbol wildcard
+    g = glob.MustCompile("?at")
+    g.Match("cat") // true
+    g.Match("fat") // true
+    g.Match("at") // false
+    
+    // create glob with single symbol wildcard and delimiters ['f']
+    g = glob.MustCompile("?at", 'f')

+
+## Performance
+
+This library is created for compile-once patterns. This means, that compilation could take time, but 
+strings matching is done faster, than in case when always parsing template.
+
+If you will not use compiled `glob.Glob` object, and do `g := glob.MustCompile(pattern); g.Match(...)` every time, then your code will be much more slower.
+
+Run `go test -bench=.` from source root to see the benchmarks:
+
+Pattern | Fixture | Match | Speed (ns/op)
+--------|---------|-------|--------------
+`[a-z][!a-x]*cat*[h][!b]*eyes*` | `my cat has very bright eyes` | `true` | 432
