+modifications are behaving the way you expect.
+
+Caveat regarding how rate rules are used by RMG and the rate parameters you input: because tunneling is
+important for many chemical reactions, the rate of a reaction may not be easily represented by
+a bi-Arrhenius fit. 3-parameter fits are more common. However, the resulting fit may report an
+'activation energy' that is much different (possibly by 10+ kcals) than the the true barrier height. 
+When RMG is assembling pressure-dependent networks, it will use barrier heights from rate rules. This can 
+lead to very inaccurate rate calculations. To avoid this issue, try to ensure that your fitted arrhenius 
+activation energy truly does reflect the reaction barrier height.

 **************************
 Analyzing the Output Files
 **************************
- 
\ No newline at end of file
+
+You will see that RMG has created multiple output files and folders: ::
+	:file:'/chemkin  input.py output.html  /pdep  /plot  restart.pkl  RMG.log  /solver  /species'
+ 
+The :file:'/chemkin' folder will likely have a large number of chemkin formatted files. In general, these can be disregarded, as you will be mainly interested in :file:'chem.inp', the chemkin formatted input file with a species list, thermochemical database, and a kinetic mechanism. The file :file:'chem_annotated.inp' is provided as a means to help make sense of species syntax and information sources. In addition, a species dictionary,:file:'species_dictionary.txt', is generated. Either chemkin file, in addition to the dictionary, may be used as inputs in the tools section of this website to better visualize the species and reactions: http://rmg.mit.edu/simulate/chemkin  
+(alternatively, you can open :file:'output.html')
+
+The :file:'/pdep' folder will contain files associated with the pressure-dependent reactions that RMG has generated. These files are formatted as input files for CanTherm. 
+
+RMG currently includes a solver for isothermal batch reactors. This is in fact a critical part of the model enlargement algorithm. If you have included simulations in your input file, the solutions will be located in :file:'/solver'. You will probably only be interested in the files with the largest number tags.

 Running a Job

+ Submitting a job is easy ::

+
+We recommend you make a job-specific directory for each RMG simulation. Some jobs can take quite a while to complete, so we also recommend using a job scheduler (if working in an linux environment).
