+## Cloning repo for the code development
+
+The easiest way to obtain and contribute to GAMBLR.viz is to do this via cloning the repository
+
+```
+cd
+git clone [email protected]:morinlab/GAMBLR.viz.git
+```
+
+In your R editor of choice, set your working directory to the place you just cloned the repo.
+
+```
+setwd("~/GAMBLR.viz")
+```
+
+Install the package in R by running the following command (requires the devtools package)
+
+```
+devtools::install()
+```
+
+As GAMBL users (GAMBLRs, so to speak) rely on the functionality of this package, the Master branch is protected. All commits must be submitted via pull request on a branch. Please refer to the [GAMBL](https://github.com/morinlab/gambl#contribution-guidelines) documentation for details on how to do this.
+
+## Function conflicts
+
+This package relies on the use of some functions (e.g. `get_gambl_metadata()`, `get_coding_ssm()` etc) that exist in 2 different versions: [GAMBLR.data](https://github.com/morinlab/GAMBLR.data) for the users who do not have access to GSC and [GAMBLR.results](https://github.com/morinlab/GAMBLR.results) for the Morin Lab users with access to GSC. If your contribution relies on the use of such functions, please follow these 2 steps:
+
+* *DO NOT* prepend the function use with `<package>::` (for example, `<package>::function()`), and
+* *DO NOT* add the corresponding package to the `@import` section of the function
+
+Following these steps will ensure correct usage of the proper function depending on which package is loaded in the session and will avoid functionality conflicts.
