+=========
+
+Package `treeprint` provides a simple ASCII tree composing tool.

+If you are familiar with the [tree](http://mama.indstate.edu/users/ice/tree/) utility that is a recursive directory listing command that produces a depth indented listing of files, then you have the idea of what it would look like.
+
+On my system the command yields the following
+
+```
+ $ tree
+.
+├── LICENSE
+├── README.md
+├── treeprint.go
+└── treeprint_test.go
+
+0 directories, 4 files
+```
+
+and I'd like to have the same format for my Go data structures when I print them.
+
+## Installation
+
+```
+$ go get github.com/xlab/treeprint
+```
+
+## Concept of work
+
+The general idea is that you initialise a new tree with `treeprint.New()` and then add nodes and
+branches into it. Use `AddNode()` when you want add a node on the same level as the target or
+use `AddBranch()` when you want to go a level deeper. So `tree.AddBranch().AddNode().AddNode()` would
+create a new level with two distinct nodes on it. So `tree.AddNode().AddNode()` is a flat thing and
+`tree.AddBranch().AddBranch().AddBranch()` is a high thing. Use `String()` or `Bytes()` on a branch
+to render a subtree, or use it on the root to print the whole tree.
+
+The utility will yield Unicode-friendly trees. The output is predictable and there is no platform-dependent exceptions, so if you have issues with displaying the tree in the console, all platform-related transformations can be done after the tree has been rendered: [an example](https://github.com/xlab/treeprint/issues/2#issuecomment-324944141) for Asian locales.
+
+## Use cases
+
+### When you want to render a complex data structure:
+
+```go
+func main() {
+    // to add a custom root name use `treeprint.NewWithRoot()` instead
+    tree := treeprint.New()
+
+    // create a new branch in the root
+    one := tree.AddBranch("one")
+
+    // add some nodes
+    one.AddNode("subnode1").AddNode("subnode2")
+
+    // create a new sub-branch
+    one.AddBranch("two").
+        AddNode("subnode1").AddNode("subnode2"). // add some nodes
+        AddBranch("three"). // add a new sub-branch
+        AddNode("subnode1").AddNode("subnode2") // add some nodes too
+
+    // add one more node that should surround the inner branch
+    one.AddNode("subnode3")
+
+    // add a new node to the root
+    tree.AddNode("outernode")
+
+    fmt.Println(tree.String())
+}
+```
+
+Will give you:
+
+```
+.
+├── one
+│   ├── subnode1
+│   ├── subnode2
+│   ├── two
+│   │   ├── subnode1
+│   │   ├── subnode2
+│   │   └── three
+│   │       ├── subnode1
+│   │       └── subnode2
+│   └── subnode3
+└── outernode
+```
+
+### Another case, when you have to make a tree where any leaf may have some meta-data (as `tree` is capable of it):
+
+```go
+func main {
+    // to add a custom root name use `treeprint.NewWithRoot()` instead
+    tree := treeprint.New()
+
+    tree.AddNode("Dockerfile")
+    tree.AddNode("Makefile")
+    tree.AddNode("aws.sh")
+    tree.AddMetaBranch(" 204", "bin").
+        AddNode("dbmaker").AddNode("someserver").AddNode("testtool")
+    tree.AddMetaBranch(" 374", "deploy").
+        AddNode("Makefile").AddNode("bootstrap.sh")
+    tree.AddMetaNode("122K", "testtool.a")
+
+    fmt.Println(tree.String())
+}
+```
+
+Output:
+
+```
+.
+├── Dockerfile
+├── Makefile
+├── aws.sh
+├── [ 204]  bin
+│   ├── dbmaker
+│   ├── someserver
+│   └── testtool
+├── [ 374]  deploy
+│   ├── Makefile
+│   └── bootstrap.sh
+└── [122K]  testtool.a
+```
+
+### Iterating over the tree nodes
+
+```go
+tree := New()
+
+one := tree.AddBranch("one")
+one.AddNode("one-subnode1").AddNode("one-subnode2")
+one.AddBranch("two").AddNode("two-subnode1").AddNode("two-subnode2").
+    AddBranch("three").AddNode("three-subnode1").AddNode("three-subnode2")
+tree.AddNode("outernode")
+
+// if you need to iterate over the whole tree
+// call `VisitAll` from your top root node.
+tree.VisitAll(func(item *node) {
+    if len(item.Nodes) > 0 {
+        // branch nodes
+        fmt.Println(item.Value) // will output one, two, three
+    } else {
+        // leaf nodes
+        fmt.Println(item.Value) // will output one-*, two-*, three-* and outernode
+    }
+})
+
+```
+Yay! So it works.
