 # Basic usage
+
 Search for packages with exact name matching "abbrev".
+
 ```sh
 sbomgr packages -N 'abbrev' <sbom file or dir>
 ```
 
 Search for packages with regexp name matching "log4"
+
 ```sh
 sbomgr packages -EN 'log4' <sbom file or dir>
 ```
 
 Search for packages in air gapped environment for name matching "log4"
+
 ```sh
 export INTERLYNK_DISABLE_VERSION_CHECK=true sbomgr packages -EN 'log4' <sbom file or dir>
 ```
+
 # Features
+
 - SBOM format agnostic and currently supports searching through SPDX and CycloneDX.
 - Blazing Fast :rocket:
 - Output search results as [jsonl](https://jsonlines.org/).
 - Supports RE2 [regular expressions](https://github.com/google/re2/wiki/Syntax)

 # Search flags
 
 ## Packages

 This section explains the flags relevant to the packages search feature.
 The packages search takes only a single argument, either a file or a directory. There are man flags which can be specified to control its behaviour.

 - `-N` or `--name` used for package/component name search.
 - `-C` or `--cpe` used for package/component cpe search.
 - `-P` or `--purl` used for pacakge/component purl search.
 - `-H` or `--checksum` used for package/component checksum value search.
