+Define slice
+++++++++++++
+
+
+.. code-block:: go
+
+    package main
+
+    import "fmt"
+
+    func main() {
+
+        var slice_1 []int
+        slice_2 := []int {}
+        slice_3 := make([]int, 0)
+
+        var slice_4 = []int  {1, 2, 3, 4}
+        slice_5 := []int {1, 2, 3, 4}
+
+        slice_6 := make([]int, 0)

+    // [] [] [] [1 2 3 4] [1 2 3 4] [1 2 3 4] [1 2 3 4] [1 2 3 4] [1 2 3 4]
+
+Notes:
+
+*   The first argument of ``make``, ``append`` and ``copy`` functions must be slice.
+
+*   The second argument of ``copy`` function also must be slice. (As a special case, it also will copy bytes from a string to a slice of bytes.)
+
+*   The ``copy`` function returns the number of elements copied, which will be the minimum of len(src) and len(dst).

+Public IPFS Gateways
+--------------------

+Docker usage
+------------
+
+
+
+.. code-block:: bash
+
+    $ export ipfs_staging=</absolute/path/to/somewhere/>
+    $ export ipfs_data=</absolute/path/to/somewhere_else/>

+
+Watch log and Wait for ipfs to start:
+
+.. code-block:: bash
+
+    $ docker logs -f ipfs_host
+
+
+The ipfs is running when you see this on the log:

+Connect to peers:
+
+.. code-block:: bash
+
+    $ docker exec ipfs_host ipfs swarm peers
+
+
+Add files:
+
+.. code-block:: bash
