+Grafana allows you to query, visualize, alert on and understand your metrics no matter where they are stored. Create, explore, and share dashboards with your team and foster a data driven culture:
 
-## Installation
+- **Visualize:** Fast and flexible client side graphs with a multitude of options. Panel plugins for many different way to visualize metrics and logs.
+- **Dynamic Dashboards:** Create dynamic & reusable dashboards with template variables that appear as dropdowns at the top of the dashboard.
+- **Explore Metrics:** Explore your data through ad-hoc queries and dynamic drilldown. Split view and compare different time ranges, queries and data sources side by side.
+- **Explore Logs:** Experience the magic of switching from metrics to logs with preserved label filters. Quickly search through all your logs or streaming them live.
+- **Alerting:** Visually define alert rules for your most important metrics. Grafana will continuously evaluate and send notifications to systems like Slack, PagerDuty, VictorOps, OpsGenie.
+- **Mixed Data Sources:** Mix different data sources in the same graph! You can specify a data source on a per-query basis. This works for even custom datasources.

-**The project located in the go-path will be your working directory.**
+## Get involved
 
-```bash
-go get github.com/grafana/grafana
-cd $GOPATH/src/github.com/grafana/grafana
-```
-
-### Run and rebuild on source change
-
-#### Backend
-
-To run the backend and rebuild on source change:
-
-```bash
-make run
-```
-
-#### Frontend
-Install front-end dependencies first:
-
-```bash
-yarn install --pure-lockfile
-```
-
-Rebuild on file change, and serve them by Grafana's webserver (http://localhost:3000):
-
-```bash
-yarn start
-```
-
-Build the assets, rebuild on file change with Hot Module Replacement (HMR), and serve them by webpack-dev-server (http://localhost:3333):
-
-```bash
-yarn start:hot
-# OR set a theme
-env GRAFANA_THEME=light yarn start:hot
-```
-
-_Note: HMR for Angular is not supported. If you edit files in the Angular part of the app, the whole page will reload._
-
-Run tests and rebuild on source change:
-
-```bash
-yarn jest
-```
-
-**Open grafana in your browser (default: e.g. `http://localhost:3000`) and login with admin user (default: `user/pass = admin/admin`).**
-
-### Building
-
-#### The backend
-
-```bash
-go run build.go setup
-go run build.go build
-```
-
-#### Frontend assets
-
-_For this you need Node.js (LTS version)._
-
-```bash
-yarn install --pure-lockfile
-```
-
-### Building a Docker image
-
-There are two different ways to build a Grafana docker image. If your machine is setup for Grafana development and you run linux/amd64 you can build just the image. Otherwise, there is the option to build Grafana completely within Docker.
-
-Run the image you have built using: `docker run --rm -p 3000:3000 grafana/grafana:dev`
-
-#### Building on linux/amd64 (fast)
-
-1. Build the frontend `go run build.go build-frontend`.
-2. Build the docker image `make build-docker-dev`.
-
-The resulting image will be tagged as `grafana/grafana:dev`.
-
-#### Building anywhere (slower)
-
-Choose this option to build on platforms other than linux/amd64 and/or not have to setup the Grafana development environment.
-
-1. `make build-docker-full` or `docker build -t grafana/grafana:dev`.
-
-The resulting image will be tagged as `grafana/grafana:dev`.
-
-Notice: If you are using Docker for MacOS, be sure to set the memory limit to be larger than 2 GiB (at docker -> Preferences -> Advanced), otherwise `grunt build` may fail.
-
-## Development
-
-### 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
-1. custom.ini
-
-In your custom.ini uncomment (remove the leading `;`) sign. And set `app_mode = development`.
-
-### Running tests
-
-#### Frontend
-
-Execute all frontend tests:
-
-```bash
-yarn test
-```
-
-Write and watch frontend tests:
-
-- Start watcher: `yarn jest`.
-- Jest runs all test files that end with the name ".test.ts".
-
-#### Backend
-
-```bash
-# Run Golang tests using sqlite3 as database (default)
-go test ./pkg/...
-```
-
-##### Running the MySQL or Postgres backend tests:
-
-Run these by setting `GRAFANA_TEST_DB` in your environment.
-
-- `GRAFANA_TEST_DB=mysql` to test MySQL
-- `GRAFANA_TEST_DB=postgres` to test Postgres
-
-Follow the instructions in `./devenv` to spin up test containers running the appropriate databases with `docker-compose`
-- Use `docker/blocks/mysql_tests` or `docker/blocks/postgres_tests` as appropriate.
-
-```bash
-# MySQL
-# Tests can only be ran in one Go package at a time due to clashing db queries. To run MySQL tests for the "pkg/services/sqlstore" package, run:
-GRAFANA_TEST_DB=mysql go test ./pkg/services/sqlstore/...
-
-# Or run all the packages using the circle CI scripts. This method will be slower as the scripts will run all the tests, including the integration tests.
-./scripts/circle-test-mysql.sh
-```
-
-```bash
-# Postgres
-# Tests can only be ran in one Go package at a time due to clashing db queries. To run Postgres tests for the "pkg/services/sqlstore" package, run:
-GRAFANA_TEST_DB=postgres go test ./pkg/services/sqlstore/...
-
-# Or run all the packages using the circle CI scripts. This method will be slower as the scripts will run all the tests, including the integration tests.
-./scripts/circle-test-postgres.sh
-```
-
-#### End-to-end
-
-Execute all end-to-end tests:
-
-```bash
-yarn e2e-tests
-```
-
-Execute all end-to-end tests using using a specific url:
-
-```bash
-ENV BASE_URL=http://localhost:3333 yarn e2e-tests
-```
-
-Debugging all end-to-end tests (BROWSER=1 starts the browser and SLOWMO=1 delays each puppeteer operation by 100ms):
-
-```bash
-ENV BROWSER=1 SLOWMO=1 yarn e2e-tests
-```
-
-### Data source and dashboard provisioning
-
-[Here](https://github.com/grafana/grafana/tree/master/devenv) you can find helpful scripts and docker-compose setup
-that will populate your dev environment for quicker testing and experimenting.
