+# Dockerfile for building libzip for android
+# https://github.com/dec1/libzip.git
+# creates docker container with all tools, libraries and sources required to build libzip for android.
+
+# Author: Declan Moran
+# www.silverglint.com
+
+
+# Usage: 
+#---------
+# download the libzip repository
+# > git clone https://github.com/dec1/libzip.git
+# > cd libzip
+#
+# build docker image "my_img_zip" from the dockerfile in "docker" dir
+# > docker build -t my_img_zip ./android/docker
+#
+# run docker container "my_ctr_zip" from this image, mounting the current dir. (Need to pass absolute host paths to mount volume- hence "pwd")
+# > docker run  -v $(pwd):/home/docker-share/libzip -it --entrypoint=/bin/bash --name my_ctr_zip my_img_zip
+#
+# Now inside docker container
+# $ cd /home/docker-share/libzip/android
+#
+# Modify ./do.sh (on host), to match the boost and android ndk versions/paths in the "Configure here" section below
+# Build from running docker container. 
+# $./do.sh
+#
+# "./build" dir contains required build, but owned by root. chown to your username/group
+# > sudo chown -R <userid>:<groupid> ./build
+# > sudo chown -R <userid>:<groupid> ./install
+#
+# Exit container, when build is finsihed.
+# $ exit
+#

+Cross compile libzip for android.
+--------------------------------
+Modify "do.sh" as appropriate if you need to specify a different ndk dir or wish to specify different build parameters
+
+Prerequisites for the development machine - see docker/Dockerfile
+
+You can either set you host machine up with these prerequisites or simply use docker (in which case you need not install anything on your host machine except docker itself).
+
+See "Usage" in docker/Dockerfile for detailed instructions.
