+## How to report issues
+
+Obs. it's important to check the current open issues for similar reports
+in order to avoid duplicates.
+
+Some general guidelines:
+
+-   Include a [minimal reproducible example](https://stackoverflow.com/help/minimal-reproducible-example) when possible.
+-   Describe the expected behaviour and what actually happened
+    including a full trace-back in case of exceptions.
+-   Make sure to list details about your environment
+
+## Setting up your environment
+
+If you intend to contribute to gomatrix you'll first need Go installed on your machine (version 1.12+ is required). Also, make sure to have golangci-lint properly set up since we use it for pre-commit hooks (for instructions on how to install it, check the [official docs](https://golangci-lint.run/usage/install/#local-installation)).
+
+-   Fork gomatrix to your GitHub account by clicking the [Fork](https://github.com/matrix-org/gomatrix/fork) button.
+-   [Clone](https://help.github.com/en/articles/fork-a-repo#step-2-create-a-local-clone-of-your-fork) the main repository (not your fork) to your local machine.
+
+        ```
+        $ git clone https://github.com/matrix-org/gomatrix
+        $ cd gomatrix
+        ```
+
+-   Add your fork as a remote to push your contributions.Replace
+    ``{username}`` with your username.
+
+        `git remote add fork https://github.com/{username}/gomatrix`
+
+-   Create a new branch to identify what feature you are working on.
+
+        ```
+        $ git fetch origin
+        $ git checkout -b your-branch-name origin/master
+        ```
+
+-   Make your changes, including tests that cover any code changes you make, and run them as described below.
+
+-   Execute pre-commit hooks by running 
+
+        `<gomatrix dir>/hooks/pre-commit`
+
+-   Push your changes to your fork and [create a pull request](https://help.github.com/en/articles/creating-a-pull-request) describing your changes.
+
+        `$ git push --set-upstream fork your-branch-name`
+
+-   Finally, create a [pull request](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/about-pull-requests)
+
+## How to run tests
+
+You can run the test suite and example code with
+
+        `$ go test -v`
+
+# Running Coverage
+
+To run coverage, first generate the coverage report using `go test`
+
+    `go test -v -cover -coverprofile=coverage.out`
+
+You can now show the generated report as a html page with `go tool`
+
+    `go tool cover -html=coverage.out`
+
