 ## Install
 
-```
-▶ go get -u github.com/tomnomnom/httprobe
+```sh
+ go get -u github.com/tomnomnom/httprobe
 ```
 
 ## Basic Usage
 
 httprobe accepts line-delimited domains on `stdin`:
 
-```
-▶ cat recon/example/domains.txt
+```sh
+ cat recon/example/domains.txt
 example.com
 example.edu
 example.net
-▶ cat recon/example/domains.txt | httprobe
+ cat recon/example/domains.txt | httprobe
 http://example.com
 http://example.net
 http://example.edu

 By default httprobe checks for HTTP on port 80 and HTTPS on port 443. You can add additional
 probes with the `-p` flag by specifying a protocol and port pair:
 
-```
-▶ cat domains.txt | httprobe -p http:81 -p https:8443
+```sh
+ cat domains.txt | httprobe -p http:81 -p https:8443
 ```
 
 ## Concurrency
 
 You can set the concurrency level with the `-c` flag:
 
-```
-▶ cat domains.txt | httprobe -c 50
+```sh
+ cat domains.txt | httprobe -c 50
 ```
 
 ## Timeout
 
 You can change the timeout by using the `-t` flag and specifying a timeout in milliseconds:
 
-```
-▶ cat domains.txt | httprobe -t 20000
+```sh
+ cat domains.txt | httprobe -t 20000
 ```

 If you don't want to probe for HTTP on port 80 or HTTPS on port 443, you can use the
 `-s` flag. You'll need to specify the probes you do want using the `-p` flag:
 
-```
-▶ cat domains.txt | httprobe -s -p https:8443
+```sh
+ cat domains.txt | httprobe -s -p https:8443
 ```
 
 ## Prefer HTTPS
 
 Sometimes you don't care about checking HTTP if HTTPS is working. You can do that with the `--prefer-https` flag:
 
-```
-▶ cat domains.txt | httprobe --prefer-https
+```sh
+ cat domains.txt | httprobe --prefer-https
 ```
 
 ## Docker
 
 Build the docker container:
 
-```
-▶ docker build -t httprobe .
+```sh
+ docker build -t httprobe .
 ```
 
 Run the container, passing the contents of a file into stdin of the process inside the container. `-i` is required to correctly map `stdin` into the container and to the `httprobe` binary.
 
-```
-▶ cat domains.txt | docker run -i httprobe <args>
+```sh
+ cat domains.txt | docker run -i httprobe <args>
 ```
