Solid entry, nice work! The only thing I'd change is "containing bson data dump" --> "containing a bson data dump".

The language can be improved a bit. Its not very clear that the data is being imported "to" the database. I would love a "from" -> "to" sentence. How about "Import a bson data dump from a folder to a given database" ?

A couple of points -

1. We try to use the spelled out version of the flags of a command. https://github.com/tldr-pages/tldr/blob/master/CONTRIBUTING.md#guidelines. Lets keep it consistent with mongo and mongodump and use --host, --db etc.

2. The same options are repeated again for the last example. The way we write these pages are introduce different options in different examples and let the user slowly build up the full command.
   So, I would suggest for the first example to drop the -h as that's used in all the following examples. Then introduce --host, --port in the 2nd one. After that, just --username in the 3rd one. Now we can have an example for a different use case, combining all the previous options. I would recommend also adding the --collection flag since we have space for some more examples.

   This is how I would build up the flags:

   1. --db
   2. --host, --port, --db
   3. --username, --db
   4. --host, --username, --port, --db (import from file)
   5. --collection, --db (import from folder, only to a particular collection)

Agree with most of the points. I feel --collection option for mongorestore need not be included here as it is rarely used ( such as collection name conflicts that will arise only if an exisiting database is merged with dump from another database).

[agnivade]

I feel --host and --port can be dropped here since they are anyways used in the next examples. Lets lay it slowly on the user 😄

LGTM from my side. Over to @waldyrious for any final comments.

This is a bit of a mouthful. We should harness punctuation to better guide reading flow, e.g.

- Import a bson data dump from a folder to a given mongodb database host, running at a given port, with user authentication (user will be prompted for password):

[waldyrious]

I've left some (mostly minor) inline comments. Additionally, I would suggest the "MongoDB" capitalization to be used in all descriptions, for correctness and to match the form used in the command summary.

I'm happy with how the page turned out. Thanks again for a great contribution!
