+# Install Julia
+RMS is written in Juila language. So before stepping any further, Julia needs to be installed. The download links can be found at [download Julia](https://julialang.org/downloads/). More instructions can be found from the [instruction page](https://julialang.org/downloads/platform/).
+
+## Standard Installation
+With julia RMS can be installed with:  
+
+```
+using Pkg
+Pkg.add("ReactionMechanismSimulator")
+Pkg.build("ReactionMechanismSimulator")
+```
+
+## Developer Installation
+Clone RMS to your machine in an appropriate location we will refer to as `RMS_PATH``:  
+```
+git clone https://github.com/ReactionMechanismGenerator/ReactionMechanismSimulator.jl.git
+```
+then you can install with 
+```
+import Pkg
+Pkg.develop(Pkg.PackageSpec(path=RMS_PATH)) 
+Pkg.build("ReactionMechanismSimulator")
+```
+
+## Testing RMS
+Unit and functional tests for RMS can be run with: 
+```
+import Pkg
+Pkg.test("ReactionMechanismSimulator")
+```
+
+## pyrms
+We also provide a python wrapper for RMS, [pyrms](https://github.com/ReactionMechanismGenerator/pyrms). Installation instructions are available on its github page. 
+
+## Julia-Python Linking
+The above instructions will automatically handle Julia-Python linking. However, in some cases it can be useful to use python from a specific conda environment. For these cases we provide instructions to relink Julia to a different Anaconda Python environment where `PATH_TO_YOUR_ENV` is the path to the Anaconda environment and `PATH_TO_PYTHON` is the path to the associated Python executable: 
+
+```
+import Pkg
+Pkg.add("PyCall")                              
+ENV["CONDA_JL_HOME"] = PATH_TO_YOUR_ENV        
+Pkg.build("Conda")                             
+ENV["PYTHON"] = PATH_TO_PYTHON                 
+Pkg.build("PyCall")                            
+```
