Clone : Remote repository  -=---->  Local repository (copying repo) 1. Clone your remote repo to your local system where to create local repo> git clone remoteURL 2. Add files to local repo & put it on remote repo > git status : how your project is progressing in comparison to you remote repo (file untracked ) > git add file.txt ---->  to track a file (move changes from the working directory to the Git staging area. The staging area is where you prepare a snapshot of a set of changes before committing them to the official history >git status > git commit -m  "message" : git commit takes the staged snapshot and commits it to the project history. --------------------------------------------------------------------------------------------------- on local system > git push origin master : specifies that you are pushing to the master branch on origin(server).

It is assumed that - errors in WebSecurity.java occured due to typo or incorrect package import. - failure of sending Http post request through Postman is caused as previous request created after endpoint change could not aceept the change for some reason. # What I did for fix - removed Spring security dependency to turn it back to previous state which has no authorization process. - tested request by creating new request in Postman * It is found that additional configuration (spring.datasource.url=jdbc:mysql://localhost:3306/test ?autoReconnect=true&useSSL=false ) does not affect server operation for now. --------------------------------------------------------------------------------------------------------------------- prerequisite : password field should be removed from UserEntity.java <!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-security --> <dependency> <groupId>org.springframework.boot</gro
