-## How to use
-
-Decompress the tar.gz file:
-
-$ tar -xvzf FileName.tar.gz
-
-Use with the RDP classifier:
-
-java -Xmx8g -jar /path/to/rdp_classifier_2.12/dist/classifier.jar classify -t /path/to/mydata_trained/rRNAClassifier.properties -o ClassifiedQueryFilename QueryFilename
+## Quick Start
+```linux
+############ Install the RDP classifier if you need it
+# The easiest way to install the RDP classifier v2.13 is using conda
+conda install -c bioconda rdp_classifier
+# Alternatively, you can install from SourceForge and run with java if you don't use conda
+wget https://sourceforge.net/projects/rdp-classifier/files/rdp-classifier/rdp_classifier_2.13.zip
+# decompress it
+unzip rdp_classifier_2.13
+# record path to classifier.jar ex. /path/to/rdp_classifier_2.13/dist/classifier.jar
+
+############ Get the latest 18S training set
+wget https://github.com/terrimporter/18SClassifier/releases/download/v4.1/18Sv4.1_mydata_trained.zip
+
+# decompress it
+unzip 18Sv4.1_mydata_trained.zip
+
+# record the path to the rRNAClassifier.properties file ex. /path/to/mydata_trained/rRNAClassifier.properties
+
+############ Run the RDP Classifier 
+# If it was installed using conda, run it like this:
+rdp_classifier -Xmx8g classify -t /path/to/mydata_trained/rRNAClassifier.properties -o rdp.output query.fasta
+# Otherwise run it using java like this:
+java -Xmx8g -jar /path/to/rdp_classifier_2.13/classifier.jar -t /path/to/mydata_trained/rRNAClassifier.properties -o rdp.output query.fasta
