+# SECOND PART

+# doc: https://crosstool-ng.github.io/docs/
+# apt-get should be all dep to build toolchain
+# sed and 1st echo are for convenience to get the toolchain in /tmp/x86_64-centos6-linux-gnu
+# other echo are to enable build by root (crosstool-NG refuse to do that by default)
+# the last 2 rm are just to save some time and space writing docker layers
+#
+# THIRD PART
+# build fpm and creates a set of deb from gem
+# ruby2.0 depends on ruby1.9.3 which is install as default ruby
+# rm/ln are here to change that
+# created deb depends on rubygem-json but json gem is not build
+# so do by hand
+
+
+# might wanna make sure osx cross and the other tarball as well as the packages ends up somewhere other than tmp
+# might also wanna put them as their own layer to not have to unpack them every time?

+# grafana-build-container
+Grafana build container
+
+## Description
+
+This is a container for cross-platform builds of Grafana. You can run it locally using the Makefile.
+
+## Makefile targets
+
+* `make run-with-local-source-copy`
+  - Starts the container locally and copies your local sources into the container
+* `make run-with-local-source-live`
+  - Starts the container (as your user) locally and maps your Grafana project dir into the container
+* `make update-source`
+  - Updates the sources in the container from your local sources
+* `make stop`
+  - Kills the container
+* `make attach`
+  - Opens bash within the running container
