 This library supports the parsing and verification as well as the generation and signing of JWTs.  Current supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own.
 
+## Installation Guidelines
+
+1. To install the jwt package, you first need to have [Go](https://go.dev/doc/install) installed, then you can use the command below to add `jwt-go` as a dependency in your Go program.
+
+```sh
+go get -u github.com/golang-jwt/jwt/v4
+```
+
+2. Import it in your code:
+
+```go
+import "github.com/golang-jwt/jwt/v4"
+```
