+applied progressively to narrow down the possible options. Each _strategy_ varies on the type
 of input data that it needs to make a decision: file name, extension, the first line of the file, the full content of the file, etc.
 
 Depending on available input data, enry API can be roughly divided into the next categories or use cases.
 
 ### By filename
+
 Next functions require only a name of the file to make a guess:
- - `GetLanguageByExtension` uses only file extension (wich may be ambiguous)
- - `GetLanguageByFilename` useful for cases like `.gitignore`, `.bashrc`, etc
- - all [filtering helpers](#filtering)
 
- Please note that such guesses are expected not to be very accurate.

+- all [filtering helpers](#filtering)
+
+Please note that such guesses are expected not to be very accurate.
 
 ### By text
+
 To make a guess only based on the content of the file or a text snippet, use
- - `GetLanguageByShebang` reads only the first line of text to identify the [shebang](https://en.wikipedia.org/wiki/Shebang_(Unix)).
- - `GetLanguageByModeline` for cases when Vim/Emacs modeline e.g. `/* vim: set ft=cpp: */` may be present at a head or a tail of the text.
- - `GetLanguageByClassifier` uses a Bayesian classifier trained on all the `./samples/` from Linguist.
 
-   It usually is a last-resort strategy that is used to disambiguate the guess of the previous strategies, and thus it requires a list of "candidate" guesses. One can provide a list of all known languages - keys from the `data.LanguagesLogProbabilities` as possible candidates if more intelligent hypotheses are not available, at the price of possibly suboptimal accuracy.

 ### By file
+
 The most accurate guess would be one when both, the file name and the content are available:
- - `GetLanguagesByContent` only uses file extension and a set of regexp-based content heuristics.
- - `GetLanguages` uses the full set of matching strategies and is expected to be most accurate.

-
-Simple and composable alternative to [regexp](http://golang.org/pkg/regexp/) package for fast substring searches.
-
-## Installation
-
-The recommended way to install substring
-
-```
-go get -t gopkg.in/toqueteos/substring.v1
-```
-
-The `-t` flag is for fetching [gocheck](https://gopkg.in/check.v1), required for tests and benchmarks.
-
-## Examples
-
-A basic example with two matchers:
-
-```go
-package main
-
-import (
-    "fmt"
-    "regexp"
-
-    "gopkg.in/toqueteos/substring.v1"
-)
-
-func main() {
-    m1 := substring.After("assets/", substring.Or(
-        substring.Has("jquery"),
-        substring.Has("angular"),
-        substring.Suffixes(".js", ".css", ".html"),
-    ))
-    fmt.Println(m1.Match("assets/angular/foo/bar")) //Prints: true
-    fmt.Println(m1.Match("assets/js/file.js"))      //Prints: true
-    fmt.Println(m1.Match("assets/style/bar.css"))   //Prints: true
-    fmt.Println(m1.Match("assets/foo/bar.html"))    //Prints: false
-    fmt.Println(m1.Match("assets/js/qux.json"))     //Prints: false
-    fmt.Println(m1.Match("core/file.html"))         //Prints: false
-    fmt.Println(m1.Match("foobar/that.jsx"))        //Prints: false
-
-    m2 := substring.After("vendor/", substring.Suffixes(".css", ".js", ".less"))
-
-    fmt.Println(m2.Match("foo/vendor/bar/qux.css")) //Prints: true
-    fmt.Println(m2.Match("foo/var/qux.less"))       //Prints: false
-
-    re := regexp.MustCompile(`vendor\/.*\.(css|js|less)$`)
-    fmt.Println(re.MatchString("foo/vendor/bar/qux.css")) //Prints: true
-    fmt.Println(re.MatchString("foo/var/qux.less"))       //Prints: false
-}
-```
-
-## How fast?
-
-It may vary depending on your use case but 1~2 orders of magnitude faster than `regexp` is pretty common.
-
-Test it out for yourself by running `go test -check.b`!
-
-```
