+# Building Grafana from source
 
 
-If you have any idea for an improvement or found a bug do not hesitate to open an issue.
-And if you have time clone [the grafana repository](https://github.com/grafana/grafana) and submit a pull request and help me make Grafana
-the kickass metrics & devops dashboard we all dream about!
+Guide for creating packages from source, and for getting grafana up and running in
+dev environment.
 
 
-Grafana uses nodejs and grunt as a build system for javascript, less compilation, and unit tests.
+## Dependencies
 
 
-## Get started
+- Go 1.4
+- NodeJS
 
 
- - Install nodejs.
- - npm install -g grunt-cli
- - npm install (in grafana repository root)
 
 
-### run development server
+## Get Code
 
 
- - grunt server
+```
+go get github.com/grafana/grafana
+```
 
 
-### run less & jshint checks
- - grunt
+The above will give an error saying there is no go code. That is because the new backend parts are in the develop branch.
 
 
-### run unit tests
- - grunt test
+## Building the backend
+```
+cd $GOPATH/src/github.com/grafana/grafana
+git checkout -t origin/develop
+go run build.go setup            (only needed once to install godep)
+godep restore                    (will pull down all golang lib dependecies in your current GOPATH)
+go build .
+```
 
 
-### create optimized, minified build
- - grunt build   (or grunt release to get zip/tar files)
+## Building frontend assets
 
 
+To build less to css for the frontend you will need a recent version of of node (v0.12.0),
+npm (v2.5.0) and grunt (v0.4.5). Run the following:
+
+```
+npm install
+npm install -g grunt-cli
+grunt
+```
+
+## Recompile backend on source change
+To rebuild on source change (requires that you executed godep restore)
+```
+go get github.com/Unknwon/bra
+bra run
+```
+
+## Running
+```
+./bin/grafana web
+```
+
+Open grafana in your browser (default http://localhost:3000) and login with admin user (default user/pass = admin/admin).
+
+## Dev config
+
+Create a custom.ini in the conf directory to override default configuration options.
+You only need to add the options you want to override. Config files are applied in the order of:
+
+1. grafana.ini
+2. dev.ini (if found)
+3. custom.ini
