 To convert an RDF file (e.g., Turtle) to Jelly, simply run:
 
 ```shell
-$ jelly-cli rdf to-jelly input.ttl > output.jelly
+jelly-cli rdf to-jelly input.ttl > output.jelly
 ```
 
 ### Convert Jelly to RDF
 
 To convert from Jelly to RDF run:
 
 ```shell
-$ jelly-cli rdf from-jelly input.jelly > output.nq
+jelly-cli rdf from-jelly input.jelly > output.nq
 ```
 
 By default, `jelly-cli` will translate files to NQuads. 
 But you can also specify the output format with `--out-format`, for example:
 
 ```shell
-$ jelly-cli rdf from-jelly input.jelly --out-format=ttl > output.ttl
+jelly-cli rdf from-jelly input.jelly --out-format=ttl > output.ttl
 ```
 
 You can specify most well-known formats supported by Apache Jena, but also a custom Jelly-Text format.

 The `rdf transcode` command turns one or more input Jelly streams into a single output stream. It's extremely fast, using a dedicated transcoding algorithm. However, the numerical values for each of the options in the output stream must be greater than or equal to those in the input stream(s).
 
 ```shell
-$ jelly-cli rdf transcode input.jelly > output.jelly
+jelly-cli rdf transcode input.jelly > output.jelly
 ```
 
 ### Inspect Jelly files
 
 To inspect a Jelly file and get basic information describing its contents, such as stream options or number of triples in the file, run
 
 ```shell
-$ jelly-cli rdf inspect input.jelly
+jelly-cli rdf inspect input.jelly
 ```
 
 You can also compute the statistics separately for each stream frame with the `--per-frame` option:
 
 ```shell
-$ jelly-cli rdf inspect input.jelly --per-frame
+jelly-cli rdf inspect input.jelly --per-frame
 ```
 
 In both cases, you will get the output as a valid YAML.
