+ "1. Create a new file named `nextflow.config` in the project directory.\n"
+ "2. Declare the configuration options by using the `params` keyword followed by variable names and their default values. For example:\n\n"
+ "```\n"
+ "params {\n"
+ " inputDir = './input'\n"
+ " outputDir = './output'\n"
+ " numThreads = 4\n"
+ "}\n"
+ "```\n\n"
+ "3. You can also override the default values in the configuration file by specifying new values when running the pipeline. For example:\n\n"
+ "```\n"
+ "nextflow run my_pipeline.nf --inputDir /path/to/input --outputDir /path/to/output --numThreads 8\n"
+ "```\n\n"
+ "4. Save the file and use it in your pipeline by calling the parameter name with the `$` symbol. For example:\n\n"
+ "```\n"
+ "process myProcess {\n"
+ " input:\n"
+ " file fastq from \"$inputDir/*_R{1,2}.fastq.gz\"\n"
+ " output:\n"
+ " file(\"${outputDir}/${sampleName}_mapped.bam\")\n"
+ " script:\n"
+ " \"\"\"\n"
+ " my_command --input $fastq --threads $numThreads --output ${outputDir}/${sampleName}_mapped.bam\n"
+ " \"\"\"\n"
+ "}\n"
+ "```\n\n"
+ "Next request.";
