 ## Installation
 
-The script has the following dependencies:
+The script uses the following packages:
+
 - latest version of the [Nontarget R Package](https://github.com/blosloos/nontarget) 
-(This should be installed
-through the devtools package)
-- [purrr](https://www.rdocumentation.org/packages/purrr/versions/0.2.5)
+(It is recommended to install this package through the devtools package)
 - [enviPat](https://rdocumentation.org/packages/enviPat/versions/2.2)
 - [stringr](https://www.rdocumentation.org/packages/stringr/versions/1.4.0)
 - [parallel](https://www.rdocumentation.org/packages/parallel/versions/3.6.2)
 
 Before running/configuring the script, call `make` while in the `/src`
-directory or copy `script.def.R` to `script.R`.
+directory or simply copy `/src/script.def.R` to `/src/script.R`.
+
+## Configuration
+
+All configuration variables are located at the top of the script.
+
+## Output
 
-## Additional Notes
+The script should print a list with data for all clusters that contain the
+isotopes to be searched for.
 
-In order to make the search run in linear time, as of right now, the entire
-data table will be sorted before searching.
+If `verbose.enable` is set to `TRUE`, files of the form `(fragment number).txt`
+containing the `pattern.search` output will be printed to the directory
+specified in `verbose.outputdir`, assuming the directory already exists.
