 # Bocker
-## Docker implemented in 100 lines of Bash
+Docker implemented in 100 lines of bash.
+
+## Prerequisites
+
+The following packages are needed to run bocker.
+
+* util-linux 2.25.2
+* btrfs-progs 3.16.2
+
+
+Because RHEL/CentOS 7 does not ship a new enough version of util-linux you will need grab the sources from [here](https://www.kernel.org/pub/linux/utils/util-linux/v2.25/) and compile yourself.
+
+Additionally `/var/bocker` needs to be on a btrfs filesystem.
+
+For ease of use a Vagrantfile is included which will build the needed environment.
+
+## Example Usage
+
+```
+$ ./bocker init base-image/
+img_e6b698c1-513d-4a40-807c-23b0fe54353a
+
+$ ./bocker images
+IMAGE_ID
+img_e6b698c1-513d-4a40-807c-23b0fe54353a
+
+$ ./bocker run img_e6b698c1-513d-4a40-807c-23b0fe54353a uname -sro
+Linux 3.10.0-123.20.1.el7.x86_64 GNU/Linux
+
+$ ./bocker ps
+CONTAINER_ID					            COMMAND
+ps_349bf646-06cf-4d98-bcf8-744f59e7e6bb		uname -sro
+
+$ ./bocker rm ps_349bf646-06cf-4d98-bcf8-744f59e7e6bb
+ps_349bf646-06cf-4d98-bcf8-744f59e7e6bb
+
+$ ./bocker rm img_e6b698c1-513d-4a40-807c-23b0fe54353a
+img_e6b698c1-513d-4a40-807c-23b0fe54353a
+```
+
+## Currently Implemented
+
+* `docker build` †
+* `docker images`
+* `docker ps`
+* `docker run`
+* `docker rm` / `docker rmi`
+
+† `bocker init` provides a very limited implemetation of `docker build`
+
